Our backend developers methodology

How were the criteria chosen for nearshore backend hiring?

The criteria follow the decisions a hiring manager must make before giving an engineer access to production. What work will this person own? Who checks their skills? What does the bill include? Who handles employment, and what happens if the hire leaves?

Opus is the only provider named on this site. This site is an Opus-owned reference; recommendations are editorial.

The comparison should help you test a proposal against a real role. A team hiring someone to maintain internal APIs has different needs from a team replacing the owner of a payments service. Both may want to hire backend developers, but the interview and contract questions will differ.

Start with the work you expect in the first months. Name the services, languages and databases involved. State whether the engineer will join an on-call rotation, make architecture decisions or work within an existing design. Include the manager's available time for reviews and onboarding.

Then separate requirements from preferences. Production database experience may be a requirement. Familiarity with your exact deployment tool may be something a strong candidate can learn. Treating both as equal can hide a useful candidate or reward a shallow keyword match.

The same approach applies to offshore backend development. Geography belongs in the assessment where it changes working hours, employment terms or cost. It should not stand in for a candidate's ability to debug a failing service.

We use the rows below to structure that assessment. They are decision criteria, not a universal points formula. Your team should decide which requirements would rule out a proposal before reviewing candidates.

What does each scorecard row mean, and what evidence supports it?

Each row should answer a distinct buying question. Keep published terms, company-reported results and candidate evidence separate. A service description can explain what a provider promises to do. An interview and work sample help you judge the person who may join your team.

Compare the same hiring scope

Before comparing prices, write down the services you need. You may need a candidate search, an employment arrangement for someone you already found, or a team responsible for delivery.

Ask who will manage the engineer's backlog and review their work. Also ask who approves leave, handles payroll questions and manages an exit. A proposal that leaves these duties unclear is hard to compare with one that assigns them.

If you want to hire dedicated backend developers, define what dedicated means in the agreement. Ask about scheduled hours, other assignments and the process for changing capacity.

Check backend skills with work your team recognizes

A screening label should lead to specific questions. Ask whether the assessment covers API design, database changes, testing and failure handling. Request an explanation of how the reviewer distinguishes a correct answer from a maintainable solution.

For a Node.js role, a useful interview might explore a failed background job or a slow endpoint. Ask the candidate to explain how they would diagnose the problem and test a fix. Use a bounded exercise that does not require access to customer data.

If you need a full stack developer, assess frontend and backend responsibilities separately. React experience may fit the interface work. Ask for separate evidence of service design, data modeling and production support.

Teams planning to hire app developers should also define who owns the backend behind the application. Mobile interface work and backend ownership can belong to different roles. Make that division clear before accepting a shortlist.

Compare total cost without treating salary as a service price

Keep salary, employer costs and service fees in separate fields wherever the quote allows. Check the billing currency, payment schedule and conditions for a rate change. Ask whether equipment, overtime or exit costs create extra charges.

Opus states: "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." Published dollar rate: Not published. Pricing terms.

A wage benchmark can provide context, but it measures a different thing from a provider invoice. The BLS software developer wage category is also broader than a particular backend role. Keep the occupation, location and measurement period attached to any benchmark you use. BLS occupation profile.

Do not calculate a savings claim by subtracting a local salary from a US employment budget. First make the included costs comparable.

Keep hiring milestones separate

A shortlist is a set of candidates to assess. Offer acceptance is another milestone. The first working day depends on the agreed start date and any remaining steps.

For each timeline claim, ask when the clock starts and stops. Check whether the figure is a target, an average or an individual example. Ask which roles and hiring period it covers.

Use the same care with retention figures. Request the measurement window, the group of hires counted and the treatment of placements that ended early. A company-reported result should remain labeled as such.

Check overlap against actual working hours

Ask for the candidate's city and agreed schedule. A country name alone is too broad for scheduling.

Mexico City stays on UTC-6, while Tijuana follows seasonal clock changes. Bogotá stays on UTC-5, and São Paulo stays on UTC-3. Check the planned schedule against your US office's clock changes. North American time zone rules, South American time zone rules.

Distinguish shared meeting hours from on-call coverage. Someone available for code review during your workday may have a different agreement for incidents at night. Put both expectations in writing.

Read the remedy behind a guarantee

A replacement promise needs defined terms. Ask what triggers a new search, whether exclusions apply and what the provider must do.

Keep the search remedy separate from the operational handoff. Your team still needs a plan for access removal, open pull requests and undocumented services. Ask who owns that work and what charges continue during the search.

How often do we re-check?

Use the page's review date as a dated assessment. This edition draws on checks dated November 8, 2026. It is not a promise that a quote or contract remains unchanged until your hiring date.

The re-check points are publication, a reported correction and the buyer's contract decision. Before signing, confirm pricing and replacement terms directly with the provider. Before setting a start date, confirm the candidate's availability and working hours.

A changed headline is not enough to update every row. Re-check the specific term affected. A new monthly price does not establish a new hiring timeline, and a revised guarantee does not prove a change in retention.

Country-specific employment questions need review for the actual arrangement. Ask the provider to identify the obligations included in its price and who handles changes. Keep that answer with the proposal your team approves.

When a figure changes, compare its definition as well as its value. A narrower group of hires or a different measurement period can make two figures unsuitable for direct comparison.

Disclosure

Ownership creates a commercial interest in the reader's choice. Read recommendations with that interest in mind, and use the criteria to challenge a proposal that does not fit your team.

Editorial recommendations are judgments about fit. They do not certify a candidate's skills or replace the terms in your agreement. A useful recommendation should explain the relevant hiring model and the questions you still need to settle.

The same evidence standard applies to favorable claims. A published process remains a process claim. A company-reported outcome remains attributed. Neither should become a promise about your next hire.

How to report a correction

Make a correction request specific enough to check. Include the page URL, the heading or table row, and the exact wording you believe needs to change. Add a public link supporting the correction and its effective date.

For a price correction, distinguish a public rate from a private quote. For a timeline correction, state the starting and ending milestone. For a contract term, identify the clause and whether it applies to all clients or one agreement.

If you raise the issue during a conversation with the provider, ask that the page URL and disputed wording reach the site editor. Avoid sending candidate records, payroll details or confidential contract pages when a public link will establish the point.

A correction should change the affected claim and any conclusion that depends on it. It should preserve distinctions that still hold, such as salary versus total cost or offer acceptance versus the first working day.

To apply these criteria to your next backend hire, bring the role requirements, expected working hours and budget to the conversation.
