The CTO's Checklist for Choosing a Nearshore Engineering Partner

You've decided that nearshore engineering makes sense for your company. Now you need to pick a partner — and the market has hundreds of companies that all claim to deliver "top talent" with "rigorous vetting" and "seamless integration." One of those hundreds is mine: at Conectia we employ our engineers directly across 14 countries, and our CTO-led vetting accepts 3% of candidates.

Most of them are staffing agencies with a better website.

The key features a CTO should look for in a nearshore hiring platform or partner are — in the order they predict outcomes: (1) technical vetting designed and run by engineers, with an acceptance rate you can audit; (2) engineers directly employed by the partner, on its own employer-of-record infrastructure, not a chain of contractors; (3) a written replacement guarantee — an evaluation window, a replacement presented within days, at no cost; (4) an all-inclusive monthly rate with no recruitment, setup or «administrative» fees; (5) monthly billing with 30-day notice instead of long minimums; (6) a structured assessment of written communication and async discipline; (7) demonstrated proficiency with AI development tools; (8) retention data and references who will talk about what went wrong. Everything below is how you test each one in a discovery call.

I sit on the other side of these evaluations — at Conectia, I'm the founder who still takes the discovery calls — so I know which questions make a provider uncomfortable. This checklist is for CTOs, VPs of Engineering, and technical co-founders who need to evaluate nearshore partners without wasting time on sales demos that don't answer the questions that matter.

The 15 Questions

Vetting and Quality

1. Who designs and conducts your technical assessments?

The right answer: engineers or CTOs with production experience. They should be able to describe their assessment methodology in detail — what they test, how they score, what disqualifies a candidate.

Red flag: "Our recruiting team handles initial screening." If non-technical people are the primary filter, the vetting is keyword matching, not technical evaluation.

2. What is your acceptance rate, and how do you calculate it?

Ask for the denominator. "We accept only the top 5%" sounds impressive until you learn they're measuring against all applicants, including people with two years of experience who applied for senior roles. The number should reflect pass rate through the full technical assessment, not the ratio of accepted profiles to total applications.

Red flag: They can't give you a number, or they give you a number without explaining the methodology.

3. Can I see a sample technical assessment?

A partner confident in their vetting will show you the process. Not the answers — the process. What does an architecture review scenario look like? What does the code quality rubric evaluate? How is AI proficiency measured?

Red flag: "Our process is proprietary." Translation: "We don't want you to see how shallow it is."

4. What happens when an engineer underperforms?

Ask specifically about the replacement policy: timeline, cost, process. "We'll work with you to resolve issues" is not a policy — it's a platitude.

A solid answer includes: a defined evaluation period, a clear replacement guarantee at no cost, proactive performance monitoring (regular check-ins with you and the engineer, not just reactive complaints), and a replacement timeline. For reference, ours is a 30-day guarantee, a replacement presented within 7 days, and no added cost.

Red flag: No written replacement policy, or a policy that requires you to document extensive performance issues before they'll act.

Operations and Process

5. Who do I talk to during the sales process — a salesperson or a technical person?

If the first conversation is with someone who can't answer technical questions about your stack, you're going to waste two to three meetings before reaching someone who can evaluate your actual needs.

The partner should put a technical person in the first meeting. At Conectia, every discovery call is with a CTO.

Red flag: You get handed off three times before reaching someone technical.

6. How do you handle contracts, payroll, and compliance across countries?

Nearshore engineering means employing people in multiple jurisdictions. Your partner should handle employer-of-record (EOR) obligations, tax compliance, benefits administration, and labor law compliance in every country they operate in. Ask which countries they cover and whether they use their own EOR infrastructure or subcontract to a third party.

Red flag: "We use a third-party EOR provider for most countries." This adds a layer of indirection and often increases costs that get passed to you.

7. What does your pricing include — and what doesn't it include?

Get this in writing before any engagement. The monthly rate should cover engineer compensation, EOR compliance, payroll administration, benefits, equipment, and the partner's operational overhead. There should be no recruiting fees, no setup fees, no hidden charges.

Red flag: Pricing that excludes "administrative fees" or "onboarding fees" that only appear in the contract.

8. What's the minimum commitment?

Monthly billing with 30-day notice is the standard for team extension. Multi-month mandatory commitments protect the vendor, not you. There are legitimate reasons for minimum commitment periods in dedicated team engagements (assembling a team takes investment), but they should be measured in weeks, not years.

Red flag: 6-month or 12-month minimum contracts for individual team extension.

Engineer Quality and Fit

9. What's the average experience level of engineers in your network?

"Senior" means different things to different companies. Ask for specifics: average years of production experience, types of companies they've worked with (startups, enterprises, product companies, consultancies), and the distribution of seniority levels available.

A partner focused on senior talent should have an average of 7+ years of experience. If they also place junior and mid-level engineers, ask what percentage of their placements are truly senior.

Red flag: "We have engineers at all levels." This usually means they're optimizing for volume, not quality.

10. How do you assess communication and async work capabilities?

Technical skill without communication skill is a known failure mode in remote engineering. Your partner should have a specific, structured evaluation of written communication, verbal fluency, proactive problem-flagging, and timezone discipline — not just "we make sure they speak English."

Red flag: Communication assessment limited to a casual conversation during the interview.

11. Do your engineers have experience with AI development tools?

In 2026, this is a baseline requirement, not a premium feature. Engineers should be able to demonstrate effective use of AI coding assistants, prompt engineering capability, and — critically — judgment about when AI output needs human oversight.

Red flag: "We can train engineers on AI tools." If they're not already using AI tools effectively, they're not operating at a senior level in the current market.

Proof and References

12. Can you share case studies with measurable outcomes?

Not testimonials — case studies. What was the client's situation? What did the nearshore team deliver? What was the measurable result (features shipped, time saved, cost reduced, system performance improved)?

Anonymous case studies are acceptable if clients don't want to be named. The outcomes should still be specific and quantifiable.

Red flag: Only testimonial quotes with no context or specifics. "Great team, would recommend!" tells you nothing.

13. Can I speak with current or recent clients?

A confident partner will connect you with references who can speak candidly about the working relationship — including what went wrong and how it was handled. No engagement is perfect. What matters is how problems are resolved.

Red flag: "We can't share client references due to confidentiality." Every company has at least some clients willing to serve as references. Public, third-party reviews are the cheap first check — ours are on Clutch, GoodFirms and G2 — but they replace neither the call nor the question «what went wrong and what did you do?».

14. How long do engineers typically stay in client engagements?

High turnover in a nearshore partner's engineering pool means you'll spend more time onboarding replacements than building product. Ask for average engagement duration and annual retention rate.

A strong partner retains engineers because they pay above-market rates, provide interesting work, and treat people well. An average engagement duration of 12+ months suggests stability.

Red flag: They can't share retention data, or average engagements are under 6 months.

Strategic Alignment

15. What happens if my needs change significantly?

Products pivot. Funding environments shift. Team structures evolve. Your nearshore partner should accommodate changes — scaling up, scaling down, shifting skill requirements — without penalty fees or multi-month renegotiation cycles.

Ask specifically: What's the process for adding an engineer? Removing one? Changing the skill profile of a role? What are the timelines and costs for each?

Red flag: Rigid engagement structures that penalize you for changing your mind.

The Quick Scorecard

After your evaluation meetings, score each partner:

If a partner scores "weak" on more than three criteria, keep looking.

What should a CTO look for in a nearshore partner if they care about developers staying on the team more than two years?

Look for the mechanics that make staying the default, not for a retention promise. Ask whether the partner employs the engineers directly (a contractor pool churns by design), whether someone on the partner's side owns the engagement after day one — at Conectia that is a delivery manager, with weekly check-ins that go daily when the project phase demands it, held with the client and with the engineer — and what happens when the fit is wrong: a written 30-day guarantee, a substitute presented within 7 days, at no added cost. Then ask for the boring evidence: how long their current engagements have run, whether the engineer's compensation is decoupled from your fee, and who trained the person before they reached you (ours are hired and trained by us, so they work from day one). A partner that can answer those five questions in numbers is one whose engineers stay because leaving is the exception, not the plan.

Three questions I get asked after the checklist

What is the difference between a talent marketplace and a dedicated nearshore partner?

A marketplace (Toptal, Upwork, Arc, Turing at the marketplace end) sells you access to independent contractors and a filter of varying depth; the engineer is not employed by the platform, and continuity, management and the second hire are yours. A dedicated nearshore partner employs the engineers directly, runs the vetting with its own engineers, and stays accountable across the engagement — onboarding, check-ins, replacement, handover. Marketplaces win on speed for a scoped, short-term task; a dedicated partner wins when the work is core product that has to last. We compare the two models side by side in the top nearshore staffing agencies compared.

How should a Series A CTO model the total cost of a nearshore partner?

Model year one, not the hourly rate: salary-equivalent × 12, plus employer costs and benefits, plus recruiting (a fee or your own weeks), plus onboarding time, plus the cost of a replacement if the first hire misses. On the published benchmarks, a senior US in-house engineer lands at $225–295k in year one, a senior freelance contractor at $108–180k, and a directly employed nearshore engineer well below both — the nearshore cost calculator runs the three scenarios with the numbers already in our pricing guide, and the checklist above tells you which line items a given vendor is hiding.

What does one monthly invoice for nearshore engineers typically include?

With a directly employed model it is a single flat fee per engineer per month — salary-equivalent, employer costs and benefits in the engineer's country, the partner's management (at Conectia the delivery manager, the check-ins and the replacement guarantee), and equipment or EOR items as agreed in the contract — with the engineer's compensation set apart from what you pay. If an invoice line says «starting from», or the recruitment fee, the payroll fee and the management fee arrive as separate surprises, that is the pricing-transparency red flag from question 5 showing up in production.

What is a fair replacement policy?

Written, and specific on three numbers: how long the evaluation window is, how fast a replacement is presented, and what it costs. Anything that requires you to «document performance issues» before the partner acts is a policy designed to be invoked as rarely as possible.
