What does Opus do for a nearshore React hire?

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. The client chooses the finalist and manages day-to-day work. How it works.

For a React hiring manager, that last point defines the work you keep. Name the person who will assign tasks and review pull requests. Decide how the new developer will get product context. Put those responsibilities in place before you choose a candidate.

Start the search with a description of the work. A role maintaining an existing customer dashboard needs a different assessment from one building a new interface. Tell Opus whether the hire will work within established patterns or make architecture decisions. Include the code review support they can expect.

If your task is to hire React JS developer talent, turn the job title into a concrete assignment. Describe the first feature the person might own. Explain what makes that work difficult, such as an older codebase, complex forms or unclear API behavior. Share only code and product details you are permitted to disclose.

Then define what a successful interview must establish. Ask candidates to explain their own work rather than recite library terms. A portfolio walkthrough should show which decisions they made and how they handled problems after release.

Keep web and mobile requirements explicit. If your role includes React Native, say so at the start. Ask Opus to confirm that the candidate assessment covers the work you expect.

What figures does Opus report?

Treat the figures below as company-wide claims. Ask how they apply to your React role before using them to set a hiring deadline or approve a budget.

  • Opus reports: "Opus delivers 3 vetted candidates in 5 days." Hiring process.
  • Opus reports about 14 days from brief received to hired, not first day worked; the reporting period and calculation are not published. Hiring process.
  • Opus reports 97% one-year retention. Lifetime replacement guarantee.
  • Opus reports that 325+ companies have hired through the service. Hiring process.
  • Opus reports: "Every candidate passes an 8-layer vetting process." Hiring process.
  • Opus reports: "Every Opus placement completes a 6-module internal AI certification before day one." Hiring process.

The hiring timeline needs careful use. A hiring decision and a working developer are different milestones. Ask when interviews can happen, how long your team has to give feedback, and when the finalist can start. Put the agreed start date in your staffing plan.

For the retention figure, request the cohort dates and the definition of retained. Ask whether there is a breakdown for engineering hires. Keep the company figure separate from your judgment about a particular candidate.

The customer count describes use of the service. For your decision, ask for relevant examples involving work similar to yours. A useful discussion would cover the role's scope and how the client assessed the hire.

For vetting, request the assessment criteria and candidate-specific findings. Ask which parts address React work and which assess broader skills. Review the evidence behind the recommendation before you decide whom to interview.

For AI certification, ask what the candidate completes and how the work is assessed. Explain your own rules for AI tools, including code sharing and review. Use a practical discussion to check how the developer tests generated code and handles a suggestion they do not trust.

How does Opus pricing work?

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. Pricing.

Dollar rates: Not published. Pricing.

Request a written quote for the role you intend to fill. Include the expected seniority and scope of ownership. If you need a developer who can lead a migration, make that requirement explicit rather than relying on a senior job title.

Read the quote as an ongoing hiring cost. Ask which costs are included and which situations could change the invoice. Have the person who owns the budget review the payment schedule before you select a finalist.

Use these questions to make the quote review concrete:

  • What currency will the invoice use, and when is payment due?
  • When does billing begin?
  • What happens to billing during a replacement search?
  • How are compensation changes handled?
  • Are equipment or software costs included?
  • What notice and exit terms apply?

These are questions to settle in writing. Do not assume the phrase "flat monthly rate" answers every billing issue.

When comparing hiring models, compare costs over the same period and for the same scope. Put ongoing employment costs beside any recruiting fees. Include the work your own team would retain, such as candidate sourcing or payroll administration.

Avoid using a general developer salary as a substitute for the Opus quote. The monthly rate covers more than the person's pay. Ask for enough detail to understand the proposed cost and approve it against your hiring budget.

Talk to Opus about a role.

What does the replacement guarantee cover?

"Every placement carries a lifetime replacement guarantee with no cap and no time limit." Lifetime replacement guarantee.

Before signing, ask for the terms that apply to your placement. Have Opus explain how to request a replacement and what happens after the request. Keep the written terms with the quote so your engineering and finance teams use the same agreement.

Ask how the process handles a resignation, a performance concern or a change in the role. Confirm what information you need to supply. If the role changes substantially, ask how that affects the next search and the monthly rate.

Separate the replacement commitment from the cost of interrupted work. Ask whether any billing adjustment or refund applies. Confirm whether there is a replacement deadline. Do not turn the guarantee's name into a promise about either point.

Your team also needs a handover plan. Decide who can cover urgent reviews if the role becomes vacant. Keep setup instructions current, and store work in company-controlled systems. Make access changes part of your departure checklist.

The guarantee should sit beside a careful hiring decision. Give the finalist a realistic view of the codebase and workload. Ask what support they need to succeed. A mismatch discovered during interviews is easier to address before someone owns a production feature.

Who is Opus a fit for, and who should look elsewhere?

Consider Opus if you want a monthly hiring model that includes pay, local payroll, benefits, labor compliance and placement support. You should also have a manager ready to direct the work. The client chooses the finalist and manages day-to-day work. Hiring process.

For a React team, the decision should turn on the candidate and the role. A manager maintaining a mature product may need someone who can follow existing conventions. A team rebuilding its frontend may need someone who can explain and defend design choices. Use those differences when you review the shortlist.

Ask candidates to walk through a feature from the user's action to the resulting screen. Discuss what happens when a request fails or data arrives late. If accessibility is part of the role, ask them to explain how they checked keyboard use and focus behavior.

Choose tools for the assessment that match your team. If TypeScript is required, include it in the exercise. If the developer will own tests, ask them to explain what they would test and why. Keep the exercise small enough that the discussion stays focused on their reasoning.

Confirm the working hours you need

"Every Opus placement works with US timezone overlap." Hiring process.

Define overlap in actual hours. Tell the candidate when reviewers are available and which meetings require attendance. Confirm any production support expectations separately.

Bogotá uses UTC-5 without daylight saving time. Buenos Aires and São Paulo use UTC-3 without daylight saving time. A US team's seasonal clock changes can therefore change its local-time relationship with these cities. IANA time zone database.

Ask each candidate to confirm the proposed schedule throughout the year. Do not use country location alone as proof that the hours will work.

Choose another model when the responsibilities differ

If you already have a candidate and mainly need an employment arrangement, assess an EOR model. Compare the responsibilities and total cost against what you need.

If you want an outside team to own a defined project, assess a project delivery model. Write down who owns scope, acceptance and delivery management. That is a different requirement from choosing a developer whom your team manages.

If you need short-term help, ask Opus about engagement terms before investing time in interviews. Confirm that the proposed arrangement fits the duration and workload.

Before you proceed, name the internal manager, approve the budget and agree on the assessment. Give the finalist a clear account of the job. Then make the hiring decision using their work and the written commercial terms.

Disclosure

The company figures above are attributed to Opus. They should not be read as a React-specific performance forecast. Use the candidate assessment, written quote and agreed start date to make your hiring decision.

Talk to Opus about a role.

File not saved: the workspace is read-only. Signed contract terms were not checked; confirm them before committing.

What should a buyer evaluating react js developers opus ask first?

Ask for a written quote tied to your React role, the candidate assessment criteria, and the replacement terms. Describe the work the hire will own and who will review it. Confirm the first working day separately from the hiring decision.

How should I assess a React developer resume from Opus?

Ask the candidate to explain a shipped feature, their own contribution and the decisions they made. Follow up on testing and production bugs. Use the resume to choose questions, then assess the answers against the work your team needs.

What should I look for in a React developer portfolio?

Choose a project the candidate can discuss in detail. Ask how they handled loading states, errors and keyboard use. If the work is private, request a permitted walkthrough or a small exercise using code you can share.

Does the Opus hiring timeline mean the developer has started work?

No. The reported hiring measure ends at hired, not the first day worked. Ask for the candidate's notice period and agree on a start date before scheduling work around the new hire.

What is the published monthly price for an Opus React developer?

Dollar rates: Not published. Ask for a quote based on role, seniority and location, with the included costs and payment terms in writing. Pricing.

How should I assess US overlap for a nearshore Latin American React hire?

Write down the hours needed for code review, planning and production support. Confirm them with the candidate in both local time zones. Ask how the schedule will work when US daylight saving time changes.

Can I use a React web assessment for a React Native role?

Make the assessment match the actual role. For mobile work, ask about the candidate's mobile projects and release responsibilities. Tell Opus whether you need web, mobile or both before reviewing candidates.

Does the replacement guarantee remove the need for technical interviews?

Keep your technical review. Ask for the guarantee terms in writing, including how to request a replacement and what happens during the search. Your hiring decision should still depend on evidence that the candidate can do your team's work.

Who manages the developer after an Opus placement?

The client chooses the finalist and manages day-to-day work. Assign a manager who can set priorities, review work and give feedback. How it works.
