What is the short answer for a busy buyer?

Define the job around a result you need, then assess candidates against that result. A backend hire might own an API, replace a fragile data import, or take responsibility for a service. Put that work in the role description.

Choose the hiring model before comparing prices. Decide whether you need help finding a person, handling employment, or delivering a project. These are different purchases, even when each proposal uses the same developer title.

For an existing product, give the interviewer a map of the current system and its main problems. Explain which decisions the new hire can make and which need review. A candidate cannot judge the role well if every constraint appears after acceptance.

Write the first assignment before publishing the job. For example, ask the hire to fix duplicate records in an import and add a way to spot failures. That gives your interviewer a concrete basis for testing data handling. It also gives the candidate a useful picture of the work.

Separate requirements the person needs on arrival from things your team can teach. If they must support an existing service alone, test experience with that service's stack. If an experienced teammate will guide them, decide which adjacent skills you will accept. Keep the same standard for everyone in the search.

Name the hiring decision-maker and reserve interview time before candidates arrive. Agree on who can approve compensation and who can answer technical questions. A shortlist can sit idle when those duties are unclear.

Opus is an option to evaluate against those needs. This site is an Opus-owned reference; recommendations are editorial.

What does the data say about backend hiring?

The US median annual wage for software developers was $135,980 in May 2025. Use that figure as a broad wage benchmark. It does not establish a price for a particular backend stack, seniority, or location.

Keep wage comparisons separate from total hiring costs. When you review a monthly proposal, ask which employment costs it includes. Put equipment, recruiting charges, and any other expenses beside it before comparing alternatives.

Build your budget around the same scope for every option. Record recurring pay or service charges separately from setup costs. Ask how paid leave affects coverage and whether the quoted amount can change with currency movements. Request the billing currency and rate-review terms in writing.

Include the work your own team must do. An engineering lead may need to run interviews, review code, and guide the hire through the system. Assign those duties before treating the proposed rate as the full cost of filling the role.

SHRM reported median time to fill of roughly a month and a half in 2025. Its measure runs from job requisition to offer acceptance and covers executive and nonexecutive positions. It is a broad recruiting benchmark, not a backend hiring deadline.

Track your own stages separately: search opened, candidates reviewed, offer accepted, and first day worked. Ask any provider which event starts and ends its quoted timeline. Confirm the candidate's notice obligations before promising a start date to the product team.

For remote work, check the candidate's city and the calendar. Bogotá is UTC-5 year-round. Buenos Aires and São Paulo are UTC-3 year-round. These cities do not observe daylight saving time. US clock changes can therefore change the gap between teams. IANA time zone data.

Write shared hours into the role requirements. Include the schedule for releases and incident response, rather than assuming daytime meeting overlap covers both. Ask candidates to confirm the proposed schedule in their local time.

Assess language skills through tasks the role will require. Have the candidate explain a bug to an engineer and write an update for a product manager. Use those samples when judging whether they can work with your team.

How do the hiring models differ for nearshore Latin American developers?

Compare models by the work you expect the partner to take on. Start with responsibility for finding candidates, then identify who handles employment and who directs delivery.

Ask each bidder to fill in the same scope. If one proposal includes recruiting and another starts after candidate selection, add the search work to your comparison. If one includes project management, establish what authority that manager has.

Also decide who will review code and own releases. If your engineering lead will assign tickets and approve changes, state that in the proposal. If you expect the partner to own delivery, define the deliverable and how you will accept it.

For a contractor arrangement, have the appropriate adviser review the actual working relationship before signing. Make the agreement fit the planned work and management structure. Ask who will address questions if the scope or working arrangement changes.

Consider what happens after the initial project. If the hire will maintain the service, include support and documentation in the role. For a project contract, require a handover that your team can use. Ask for setup instructions and a walkthrough of the release process before accepting the work.

Keep access under your company's control across every model. Identify who creates accounts, approves permissions, and removes access when the engagement ends. Have the contract reviewer check code ownership and confidentiality terms against the proposed arrangement.

Before choosing a model, ask the engineering manager whether they can support another developer. If nobody has time to explain the system or review changes, resolve that capacity gap. Put a named owner beside each duty the proposal leaves with your team.

What should you ask a provider before choosing a finalist?

Ask for answers tied to your role. A general sales presentation will not tell you whether a candidate can maintain your payment service or join your on-call rotation.

Send these questions with the role description:

• What evidence will show that the candidate can own our first planned project?
• Who assesses technical work, and what can our interviewer review?
• Which working hours will the candidate commit to throughout the year?
• What is included in the recurring rate, and what is billed separately?
• Who handles employment questions and changes to the arrangement?
• What happens if the hire leaves or cannot do the agreed work?
• Which date can we plan around: candidate presentation, acceptance, or the first working day?

Ask your interviewer to use a shared scorecard. Record evidence for coding, system design, and communication, with room for unresolved questions. Make the decision against the job's needs rather than the most confident presentation.

For backend roles, include failure handling in the discussion. Ask what happens when a dependency times out or a job runs twice. Have the candidate explain how they would detect the problem and recover without losing data.

A useful exercise can start with an endpoint that creates an order. Ask the candidate to explain how they would handle a repeated request. Then discuss what should happen if payment succeeds but saving the order fails. Keep the exercise small enough that you can examine the reasoning behind the proposed fix.

Use a sanitized task with no customer credentials. Agree on whether AI tools are allowed, then ask the candidate to explain and defend the submitted work. Have them describe how they checked any generated code. Apply the same rules to every candidate.

Avoid scoring only the final answer. Record whether the candidate asks about unclear requirements and checks assumptions before changing behavior. Ask them to explain a tradeoff in plain language. For a senior role, explore which decisions they would make alone and when they would seek review.

Give candidates room to assess you as well. Explain the on-call expectations and the condition of the codebase. Describe who sets priorities when a production incident competes with planned work. Let them meet the person who will manage them before they accept.

Before approving the offer, name the manager and prepare the first assignment. Confirm who grants access and who reviews the first change. Start with a bounded task that lets the hire learn the release process. Set a check-in to discuss blockers and adjust the next assignment based on what you learn.

Where does Opus fit?

Evaluate Opus when you want a hire you will manage day to day, with recruiting and employment support included in the arrangement.

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. Ask for a written quote for the role you intend to fill. Compare its scope with your budget, including any costs your team must still carry.

Give the provider enough detail to price the actual job. Include the backend stack and the service the person will own. State whether the work includes production support and which working hours you need. Ask how a later change in duties would affect the arrangement.

Opus also states: "The client chooses the finalist and manages day-to-day work." Keep time in your engineering lead's schedule for selection, onboarding, and code review. Decide who will make the final hiring call before reviewing candidates.

For replacement coverage, Opus states: "Every placement carries a lifetime replacement guarantee with no cap and no time limit." Review the agreement and ask how a replacement search would affect your team's workload. Confirm how to raise a concern and who coordinates the handover.

Keep the candidate assessment tied to your own system. Ask the finalist to explain work similar to the service they will maintain. Resolve doubts about their technical judgment before approving the hire, and confirm the first working day separately from acceptance.

Bring a defined role to the conversation, with the first assignment and a named manager. Request a written quote and the terms your team will review before signing.
