What is the short answer for a busy buyer?
Hire against the work you need done. An engineer building a customer support assistant needs different evidence from someone training a forecasting model. Give the search owner a concrete task and an acceptance test before asking for candidates.
Start with a short role brief. Name the system, explain who uses it, and describe the first change the hire will own. State whether the person will develop models or use existing ones. Include the person who will review their work.
For example, a search assistant role might involve connecting approved documents to an existing model. Ask the candidate to show how answers link back to those documents. Include a question the documents cannot answer. Review whether the system admits that limit or invents a response.
A model development role needs a different exercise. Ask how the candidate would select training data and keep test data separate. Have them explain how they would compare a proposed model with the current approach. Choose an assessment that matches the decisions they will make at work.
Keep AI training separate from the hiring decision. Ask what the course covers, then test the skills your project needs. Someone using AI to draft internal reports may need different training from an engineer responsible for a customer-facing service.
Write down what the hire will not own, too. If another team manages data access or releases, name that team. Candidates should know which decisions they can make and where they need approval. This also gives your interviewer a fair basis for judging their answers.
Opus is one option to assess against that role brief. This site is an Opus-owned reference; recommendations are editorial.
What does the data say about pay and hiring time?
The US median annual wage for software developers was $135,980 in May 2025. That is a broad software developer benchmark, not a quote for an AI specialist or a complete employment budget. Keep the occupation and date attached when using it in a budget discussion. BLS software developer pay.
For a specific opening, request a quote based on the work and seniority. A role that calls for model research should have its own assessment and budget. So should a role that owns a production service outside normal working hours. Avoid applying one salary figure to every job with AI in its title.
Build your comparison around the same scope. Give each provider the same role description, location requirements, and expected hours. Ask which costs recur and which arise only when something changes. Keep model API usage and cloud spending separate from the cost of employing the engineer.
SHRM reports that median time to fill in 2025 was roughly a month and a half for executive and nonexecutive positions. Its measure runs from job requisition to offer acceptance. It does not measure the time until a new hire starts work. SHRM recruiting benchmarks.
Use separate dates in your hiring plan:
- The date the search begins.
- The date you expect to review a shortlist.
- The date you need an accepted offer.
- The first working day.
Ask a provider which milestone its speed claim measures. Keep your own interview turnaround in the plan, too. A shortlist cannot move to an offer while the hiring manager's review is pending.
Before opening the search, reserve time for technical interviews and a decision meeting. Confirm who can approve compensation. If the preferred candidate needs a later start, decide who can accept that change. These are decisions your team can prepare before any candidate arrives.
Compare reported hiring speed only after checking the start and end points. Ask whether the figure covers roles like yours and how the provider treats searches that remain open. Use the answer to set expectations with your team, rather than turning a broad benchmark into a promised start date.
How do hiring models differ for nearshore and Latin American teams?
Choose a model by the responsibility you need someone else to take. Finding a candidate, employing them, and managing a project are separate jobs. Put an owner beside each before comparing prices.
| Hiring model | Buyer task | Question to settle before signing |
|---|---|---|
| Direct hiring | Run the search and arrange employment | Who owns the local employment setup? |
| Recruiting agency | Review candidates and arrange employment | What work and fees end at placement? |
| Employer of record | Bring a selected candidate and manage daily work | Which entity employs the person? |
| Placement with ongoing employment support | Choose the finalist and manage their work | What does the monthly rate include? |
| Outsourced project | Define the deliverable and acceptance criteria | Who owns delivery and handles scope changes? |
A contingency recruiter charges a fee for a successful hire; that fee does not cover ongoing employment. Ask for the payment trigger and the employment responsibilities left with your company. Recruiting fee and employment cost distinction.
If you already have a finalist, ask whether you need search services at all. Request a proposal for the work you still need. If you need both a search and ongoing employment support, ask the provider to explain how those responsibilities connect.
Choose the manager before choosing the model. If your engineering lead assigns tasks and approves code, include that in the working plan. If you are buying a finished project, specify acceptance tests and who pays for changes to the agreed scope. Also decide who maintains the result after delivery.
For LatAm hiring, confirm the person's city and schedule. Mexico City stays at UTC-6 without daylight saving time. Bogotá stays at UTC-5, and Buenos Aires stays at UTC-3. US clock changes can alter the difference between those cities and your team. North American time-zone rules, South American time-zone rules.
Put shared working hours in writing. A general promise of overlap does not tell you whether someone can attend your release review. Identify meetings that require live attendance and work that can move through written updates.
Do the same for incident response. Ask whether after-hours support is part of the role, how coverage is assigned, and who serves as backup. Confirm those expectations before the offer so the candidate can assess the actual schedule.
What should you ask a provider before reviewing candidates?
Ask for assessment evidence you can use in a hiring decision. A score without the task, scoring criteria, and reviewer's notes gives your manager little to inspect. Request enough detail to understand why each candidate made the shortlist.
For an AI application role, use a work sample that includes failure cases. Have the candidate explain how they would detect a wrong answer and prevent sensitive data from reaching an unapproved service. Use synthetic data during the assessment.
Keep the exercise small and pay for work that takes meaningful time. Tell candidates which tools they may use. If AI assistance is allowed, ask them to explain the resulting code and change it during a review. Judge their understanding of the work they submit.
Ask these questions before accepting a shortlist:
- What did the candidate build, and which parts did they personally own?
- Who reviewed the code, and what did that review find?
- How did you assess written communication?
- What working hours has the candidate agreed to?
- Which skills still need our technical interview?
For AI training, request the syllabus and assessment criteria. Ask whether participants complete a practical task and how failed work is handled. Match the course content to the job. If the role includes production access, ask candidates to explain how they would test a change before releasing it.
Then review the commercial terms. Ask for a written price with inclusions and exclusions. Confirm how pay changes affect the bill and what happens when a hire leaves. Ask who handles equipment, account setup, and the return of company property.
Have the provider explain the proposed employment arrangement for the worker's country. Request the contracting entities and a clear division of responsibilities. Send specific questions to your legal or HR reviewer before signing, while there is still time to change the arrangement.
Give your own team an interview deadline. Name the decision-maker and record the reasons for rejecting a candidate. Feedback tied to the role helps the next search focus on the right gaps. Replace comments such as "not senior enough" with the task or judgment the person could not demonstrate.
Prepare the first assignment before the offer is accepted. Choose a bounded change with a reviewer and a clear test of success. Confirm that the new hire will have approved access to complete it. Otherwise, the first week can become a series of permission requests.
Where does Opus fit?
Opus reports that every candidate passes an 8-layer vetting process. It also reports that every placement completes a 6-module internal AI certification before day one. Ask how that assessment maps to your role's work sample. Opus hiring process.
Treat the internal certification as a topic for your technical interview. Ask what the candidate learned and have them apply it to a task your team recognizes. Decide separately whether they have the engineering depth needed to own your system.
The client chooses the finalist and manages day-to-day work. Assign someone who can judge the work before you begin interviewing. That manager should also own the first assignment and the feedback the hire receives. 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. Published dollar rate: Not published. Ask for a written quote for your opening. Opus pricing.
Opus reports that every placement carries a lifetime replacement guarantee with no cap and no time limit. Review the agreement before signing and plan how your team will transfer work if a replacement is needed. Opus replacement guarantee.
Keep code and working notes in company-controlled systems from the start. Assign a backup reviewer who can follow the work. A replacement search and a handover solve different problems; plan for both when assigning ownership of a production service.
Bring the role description, required working hours, and proposed assessment to the conversation. Ask which candidate evidence you will receive before choosing a finalist. Request a quote against that same scope so your technical and commercial reviews concern the same job.

Questions & answers
what companies hire ai engineers, and what work do they need?
Look for employers building AI products or adding AI to existing systems. For your own opening, specify whether the engineer will develop models, build applications, or operate production services.
What companies hire software engineers?
Look for employers building or maintaining customer software and internal systems. Describe the codebase and expected ownership in your posting so candidates can assess the actual work.
What companies hire the most engineers?
Define whether you mean engineering headcount, current vacancies, or completed hires. Compare employers competing for your required skills rather than using total company size as a hiring benchmark.
What companies hire computer engineers?
Search for work involving hardware and embedded software. For your own role, specify the devices, operating limits, and whether the engineer needs access to physical equipment.
How do you hire AI developers?
Define a concrete task, use a paid work sample with synthetic data, and have your technical lead review it. Ask the candidate to explain tests and failure handling.
How do you hire AI engineers?
Separate model development from application engineering and production operations. Assess the skills your project needs, then agree on the first deliverable and who will review it.
Does AI training qualify someone to build production systems?
Treat training as part of the assessment. Ask candidates to demonstrate testing, access controls, and failure handling. A certificate alone should not settle the hiring decision.
What should an AI developer work sample include?
Request working code, tests, and a short explanation of design choices. Include bad input and a case where the system should decline to answer.
What are staffing companies?
Staffing companies help clients fill roles. Ask whether the proposed service covers candidate search, ongoing employment, or both, and confirm what your own team must manage.
What do staffing companies do during a technical search?
Ask for a written account of sourcing and assessment. Request the task, scoring criteria, and reviewer notes behind each shortlist decision before scheduling your final interview.
What is outsourcing and why do companies use it?
Outsourcing means paying an outside business to perform work. A buyer might need project delivery or specialist skills. Define whether you are buying a deliverable or adding a person.
How does an employer of record differ from an umbrella company?
Compare the actual contracts and country arrangements. Ask who signs the employment agreement, runs payroll, and handles employment duties; the labels alone do not settle those responsibilities.
When should you use a recruiter instead of an EOR?
Consider a recruiter when you need candidates and can arrange employment. Consider an EOR when you have selected someone and need an employment arrangement in their country.
What companies are hiring remote workers?
Check current employer careers pages and read each role's location restrictions. For your own posting, state eligible countries, shared working hours, and any required travel.
How should you assess a nearshore or Latin American AI engineer?
Use the same technical standard for every candidate. Add a live working session during shared hours and ask for a written explanation of a technical decision.
How much US time-zone overlap should you require?
Set hours around code reviews, customer meetings, and support duties. Confirm the schedule across clock changes and include the agreed hours in the role requirements.
What companies hire robotics engineers?
Look for work involving sensing, motion, and physical control. Specify lab access and hardware testing needs before deciding whether your own robotics role can be remote.
What companies hire environmental engineers?
Search by work such as water treatment or pollution control. If your project includes AI, separate software tasks from the engineering judgments that need specialist review.
What companies hire nuclear engineers?
Look for roles tied to nuclear systems and research. Define specialist qualifications and site access before hiring, including who approves any work that uses AI.
What companies hire industrial engineers?
Search for roles focused on production processes and operational performance. For an AI project, specify the process being changed and how the team will measure results.
What companies hire software developers?
Look for employers building or maintaining software. In your own opening, distinguish between using AI tools to write code and building an AI product.
How should you compare AI hiring costs?
Compare the same role, seniority, and location. Ask about recurring charges and exclusions. Budget separately for model usage, cloud services, and the manager's review time.
What should a replacement guarantee cover?
Ask what starts a replacement search, which fees apply, and what you must do. Confirm how ongoing work and access removal will be handled during the search.
What should be ready before the engineer starts?
Assign a manager and a small first task. Prepare approved access, define a successful result, and name the person who can approve production changes.
