What shared hours should a busy buyer require?
Write down the meetings and decisions the hire must join before choosing a country. A developer who can attend standup may still finish work before your team starts reviewing pull requests.
Use the manager's actual calendar. Include design reviews, release checks, and time when someone can answer a blocked developer's question. Decide which activities need a live conversation and which can wait for a written reply.
If you plan to hire Latin American developers, make the schedule part of the role description. Name the US city, the required shared window, and the expected local workday. Ask candidates to confirm that schedule during interviews.
A useful hiring requirement might read:
The developer must be available during our agreed core hours in America/New_York. We will confirm the local schedule for both US standard time and daylight time before the offer.
Replace "agreed core hours" with the actual window before sharing the role. Include breaks and who approves schedule changes. Record on-call duties separately so meeting availability does not become an open-ended support obligation.
Check the work that happens after standup
Walk through a recent task that needed help from another person. When did the developer ask a question? When could the reviewer respond? Would the proposed schedule allow the developer to act on that response before finishing work?
Move a review slot if the reviewer can reasonably change their calendar. If it cannot move, make its timing a hiring requirement. Apply that requirement to every candidate.
Also distinguish being online from being free to collaborate. If the shared window is full of customer calls, another overlapping developer will not create review capacity. Reserve time with the people who can answer questions and approve work.
What do the overlap tables show by US city?
These tables assume both people work from 9 a.m. to 5 p.m. in their own city. Each cell shows shared clock hours before subtracting breaks or other commitments.
The standard-time snapshot uses January 15, 2027. The daylight-time snapshot uses July 15, 2026. Calculations follow North American time-zone rules and South American time-zone rules. They describe intersecting schedules, not measured employee availability.
During US standard time
| Developer's city | New York | Chicago | Denver | Los Angeles |
|---|---|---|---|---|
| Mexico City or Monterrey | 7 hours | 8 hours | 7 hours | 6 hours |
| Tijuana | 5 hours | 6 hours | 7 hours | 8 hours |
| Bogotá or Lima | 8 hours | 7 hours | 6 hours | 5 hours |
| Buenos Aires or São Paulo | 6 hours | 5 hours | 4 hours | 3 hours |
| San José, Costa Rica | 7 hours | 8 hours | 7 hours | 6 hours |
| Santiago | 6 hours | 5 hours | 4 hours | 3 hours |
| Montevideo | 6 hours | 5 hours | 4 hours | 3 hours |
Calculated from North American and South American time-zone rules under the stated workday assumption.
During US daylight time
| Developer's city | New York | Chicago | Denver | Los Angeles |
|---|---|---|---|---|
| Mexico City or Monterrey | 6 hours | 7 hours | 8 hours | 7 hours |
| Tijuana | 5 hours | 6 hours | 7 hours | 8 hours |
| Bogotá or Lima | 7 hours | 8 hours | 7 hours | 6 hours |
| Buenos Aires or São Paulo | 7 hours | 6 hours | 5 hours | 4 hours |
| San José, Costa Rica | 6 hours | 7 hours | 8 hours | 7 hours |
| Santiago | 8 hours | 7 hours | 6 hours | 5 hours |
| Montevideo | 7 hours | 6 hours | 5 hours | 4 hours |
Calculated from North American and South American time-zone rules under the stated workday assumption.
Read the shared window as well as the total
New York teams should check late-afternoon meetings when considering Buenos Aires or São Paulo. Those developers finish their assumed local workday earlier than their New York colleagues.
Chicago teams get a matching clock with Mexico City and San José during US standard time. Bogotá and Lima match Chicago during US daylight time. Denver matches Mexico City and San José during US daylight time.
Los Angeles teams get a matching clock with Tijuana in both snapshots. Collaboration with Buenos Aires and São Paulo falls earlier in the Los Angeles workday. These comparisons follow the North American and South American rules used above.
Once you have a candidate's agreed hours, replace the assumed workday. Convert both schedules into the same time zone. Find the later start and earlier finish, then remove breaks from that interval.
Repeat the check for the manager and code reviewer. If they work in different cities, the developer may need separate windows with each person.
Check daylight saving by city
Mexico City, Monterrey, and San José stay at UTC-6. Bogotá and Lima stay at UTC-5. Buenos Aires, São Paulo, and Montevideo stay at UTC-3. Tijuana follows US daylight saving changes. See the North American and South American time-zone records.
Santiago's clock changes follow a different schedule from US changes. The snapshots therefore do not describe every transition week. Check the actual date of a meeting before confirming availability. IANA South American rules
Use named calendar zones such as America/New_York and America/Bogota. Decide whether the workday stays fixed to the developer's local clock or follows the US team's clock.
Assign someone to inspect recurring invitations before each relevant change. These tables cover named cities, so do not apply Denver's column to every Mountain Time location.
Put holidays beside the meeting calendar
Time-zone overlap assumes both people are working that day. Confirm the applicable holiday calendar and planned leave before assigning a release.
This site is an Opus-owned reference; recommendations are editorial.
Use the Opus holiday planner when reviewing calendars, then have the employment contact confirm which dates apply to the hire.
Check the US team's absences too. A developer may be working while their manager is away. Leave written priorities and name someone who can answer questions or approve work.
How do nearshore hiring models change schedule ownership?
Compare proposals by responsibility. Establish who finds the candidate, who handles employment, and who approves the working schedule.
Use the same availability requirement across the models you consider.
| Hiring model | What to establish | Schedule question |
|---|---|---|
| Direct hiring | Who runs the search and handles employment | Who records hours and approves changes? |
| Recruiting agency | What the search fee covers | Does screening test the exact shared window? |
| Employer of record | Whether you already have a candidate and need a legal employer | How do agreed hours reach employment documents? |
| Combined recruiting and employment support | Which search and ongoing tasks are included | Who resolves a schedule mismatch after hiring? |
| Outsourced delivery | Whether you buy an individual's time or a defined result | Who attends meetings and controls availability? |
Confirm the schedule with the candidate
Give the search contact a written availability requirement. Ask to see the candidate's local hours beside yours when reviewing the profile.
Then discuss the schedule with the candidate. Ask whether the proposed workday is sustainable, including its least convenient recurring meeting. Occasional flexibility does not establish agreement to a permanent late shift.
A university name cannot answer this question. Even a shortlist drawn from the best Latin American universities needs separate checks of technical skill and working hours.
Keep the approved schedule attached to the hiring record. Ask the employment contact to confirm those same hours before preparing the agreement.
Keep management duties explicit
Decide who owns delivery planning and code review. Name the person the developer should contact when blocked, and check that person's availability.
For outsourced delivery, establish whether the agreement guarantees access to a particular person. For an individual hire, confirm the manager and reviewer before onboarding.
Ask each provider to distinguish ordinary working hours from release coverage and standby support. Send the same requirements with every quote request so you can compare the same job.
What should you ask a provider before accepting a shortlist?
Ask for a schedule you can place beside your team's calendar. "Works US hours" needs a start time, an end time, and a named time zone.
Which city will the developer work from?
Get the working city and calendar time-zone name. Ask about planned moves or extended work from another location.
Agree who approves a location change. Review the shared hours again if the person moves, and ask the employment contact to assess the arrangement.
What are the agreed hours in both seasons?
Request the developer's local start and finish beside the US team's hours. Include breaks and identify which clock governs the schedule.
Put that answer in the offer and onboarding notes. An interviewer's assumption should not become a working-hours requirement after acceptance.
Which meetings are required?
Send a sample calendar before the offer. Identify required sessions, optional sessions, and updates that can be written.
Include the manager and reviewer in this check. A developer's availability has limited use when the person who can approve their work cannot attend.
If your team spans US time zones, choose the calendar that governs the role. Separate managers should not each assume the developer follows their hours.
How will releases and urgent issues work?
Describe the release process before asking for late coverage. Have the provider confirm terms for work outside the ordinary schedule.
Define an urgent issue, its reporting channel, and the responsible responder. State when a message can wait until the next workday.
A candidate attending an interview late at night has not accepted that recurring shift. Ask directly about the expected working day.
How will holidays and schedule problems be handled?
Confirm how leave reaches the team calendar. Name a backup for approvals and production access, with permissions arranged before the absence.
Ask who handles recurring availability problems. During onboarding, inspect work that waits overnight because a decision arrives after sign-off. Try an earlier review window before requesting a longer workday.
What should a buyer know about while taking tech hiring in Detroit to the next level?
Separate work that requires a Detroit location from work that requires access to Detroit colleagues. Put both requirements in the role description before comparing candidates.
Detroit uses Eastern Time and follows the same seasonal offsets as New York. Use the New York columns for an initial comparison, then confirm the schedule with America/Detroit. IANA North American rules
If the job requires physical equipment or regular workplace attendance, specify that directly. Ask the responsible internal team whether remote access can support the work.
For remote roles, examine where tasks wait today. A pending product decision or an unavailable reviewer can block work even when everyone's clocks match.
Test a Detroit workweek before widening the search
Take a representative team calendar. Remove meetings the developer does not need, then check the sessions and follow-up work that require live participation.
| Detroit team's requirement | Candidate check | Manager preparation |
|---|---|---|
| Design discussion | Sustainable local meeting time | Decision-maker attendance |
| Code review before sign-off | Time to respond to comments | Reserved reviewer window |
| Release participation | Agreed coverage and finish time | Release owner and backup |
| Physical equipment access | Whether remote work is practical | Approved access method |
Use the same technical assessment for local and nearshore candidates. Ask the person to explain a tradeoff relevant to the role and write a short handoff for another engineer. Use a fictional or sanitized task with an agreed effort level.
Keep skill and schedule judgments separate. A strong technical interview does not resolve an unavailable reviewer, and a matching clock does not demonstrate engineering judgment.
What should a buyer know about hire developers in Detroit, Michigan or anywhere in the world?
Define where the person may work before advertising globally. Share required hours early enough for candidates to decline before a lengthy interview process.
For Detroit teams comparing Latin American developers, use the Eastern Time columns above. For other locations, apply the same calendar check using the candidate's city and actual meeting dates.
Compare the same job across locations
Use consistent responsibilities and technical criteria for every finalist. Add physical presence only where the work requires it.
A local job with office attendance and a remote job with evening coverage are different arrangements. Resolve those differences before comparing costs or deciding which candidate fits.
Record the working schedule separately from the technical scorecard. This keeps the hiring discussion specific when a candidate meets the skill bar but cannot attend a required session.
Confirm employment and start-date ownership
Ask who will be the legal employer, who handles payroll, and who prepares the agreement. Have the employment contact review the proposed arrangement in the candidate's location.
Confirm what the quote includes and what needs separate approval. Establish who provides equipment and grants system access.
Reserve interview slots and name the final decision-maker before the search starts. If interviewers disagree, address the specific concern with a focused follow-up.
Separate offer acceptance from the first working day. Check the candidate's start availability alongside equipment delivery and account access. Give the manager an onboarding plan before confirming the date.
How should shared hours shape onboarding?
Choose an initial task with clear acceptance criteria and an available reviewer. The developer needs access to someone who can explain the codebase during the agreed workday.
| Before the start | Owner to assign | Completion evidence |
|---|---|---|
| Confirm local and US hours | Hiring manager | Candidate-approved schedule |
| Review recurring meetings | Team lead | Invitations checked in both calendars |
| Confirm holidays and leave | Employment contact | Applicable calendar shared |
| Prepare system access | System owner | Access checked from the working location |
| Assign initial work | Engineering manager | Task and reviewer recorded |
After a representative task, review where waiting occurred. Missing context needs a better handoff. Late review comments may need an earlier review slot. An unavailable specialist may require a different assignment.
Agree where blockers are recorded and how the manager acknowledges them. Written handoffs should state the current task status, the decision needed, and whether work can continue.
Protect uninterrupted work within the shared day. Keep required meetings focused on decisions that need discussion, and revisit the schedule when managers or reviewers change.
Where does Opus fit in this hiring decision?
Assess Opus when you want candidate search and ongoing employment support in the same arrangement. Send the required schedule during role intake so candidates can review it before interviews.
The client chooses the finalist and manages day-to-day work. Your manager therefore needs to approve the working hours and prepare the review process. Opus hiring process
Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location. Opus pricing
Published dollar rates: Not published. Ask for a written quote for the role and working location.
Send the manager's US city, required shared hours, and meetings near the workday's edges. Include any planned release coverage. Ask for each finalist's local schedule during both US standard time and daylight time.
Before choosing someone, review a sample week together. Confirm when questions get answered and code gets reviewed. Have the employment contact carry the agreed schedule into the final documents.
Questions & answers
How should I compare overlap when I hire full time developers?
Start with required meetings and review windows. Convert those hours into each candidate's local time for both US standard time and daylight time. Confirm the schedule with the candidate before making an offer.
Which nearshore cities match a New York workday most closely?
Bogotá and Lima match New York during US standard time and sit one hour behind during US daylight time. Confirm the candidate's actual workday before treating that clock match as availability. IANA time-zone rules
Which cities should a Chicago team compare first?
Mexico City, Monterrey, and San José match Chicago during US standard time. Bogotá and Lima match Chicago during US daylight time. North American rules and South American rules
Can a Los Angeles team work with developers in Buenos Aires?
Yes, if the agreed schedule fits the role. Local workdays of 9 a.m. to 5 p.m. share three hours during US standard time and four during US daylight time. Discuss any later local finish before making an offer. North American rules and South American rules
Does Mexico follow the same daylight saving rules everywhere?
No. Mexico City and Monterrey stay at UTC-6, while Tijuana follows US daylight saving changes. Ask for the candidate's city and named time zone. IANA time-zone rules
Why should a Denver team check both seasons?
Mexico City matches Denver during US daylight time and is one hour ahead during US standard time. Check whether required meetings still fit the candidate's local schedule after the clock change. IANA time-zone rules
Does full-time employment mean a developer works my full US day?
Confirm that separately. Record the local workday, required shared hours, breaks, and any on-call duties in the written agreement. Full-time status alone does not define a US meeting schedule.
How should a Detroit team compare nearshore developer availability?
Use Detroit's Eastern Time calendar and check required meetings against the developer's local schedule. Detroit follows the same seasonal offsets as New York, so the New York columns provide an initial comparison. IANA time-zone rules
How should we handle local holidays?
Confirm the applicable holiday calendar before the start date. Review release dates against planned absences and assign backup owners. Keep holiday coverage separate from daily overlap.
Should every meeting move when US daylight saving changes?
Choose which meetings stay fixed to the US clock and review their effect on the developer's local schedule. Confirm recurring invitations before the change, especially near the start or end of the workday.
