Staff augmentation vendor checklist: questions to ask

The questions to ask before adding engineers from a staff augmentation partner, what good answers sound like, and the red flags that should end the conversation.

By the Ryz Labs team · Updated October 2026

Before you add engineers from a staff augmentation vendor, ask about five things: how they vet engineers, who exactly you will get, how those engineers will work with your team, what happens if someone is not the right fit, and how cost is structured. Good vendors answer with specifics: pass rates, named profiles, exact working hours, a replacement process and cost by role. Use the checklist below on every vendor call, and the reference script before you decide.

Staff augmentation vendor checklist

1. Questions to ask every vendor

Vetting and quality

☐ How do you source engineers, and how many candidates do you interview for each one you accept?
☐ What does your technical vetting include (live coding, system design, domain interviews), and who runs it?
☐ Can you share an anonymized example of a vetting report?
☐ How do you check English communication and remote collaboration skills?
☐ How do you review AI-generated code, and what do you expect engineers to do before merging it?

The engineers you will get

☐ Can we see profiles of the specific engineers you would propose, before we decide?
☐ Can we interview them ourselves, with our own technical questions?
☐ What seniority are they, and what systems similar to ours have they built?
☐ How long have they worked with you, and how long do engineers typically stay on a client team?

Working with our team

☐ What hours will they work in our time zone, and how much real-time overlap will we have?
☐ Will they join our standups, use our repos, tools and tickets, and report to our engineering leads?
☐ Who do we talk to if something is not working, and how fast do they respond?
☐ How do you support the engineer outside our team (mentoring, technical growth, retention)?

Fit, replacement and continuity

☐ What happens if an engineer is not the right fit? How fast is a replacement, and is it free?
☐ How is knowledge handed over when someone leaves or rotates off?
☐ How quickly can you add engineers if we need to grow the team?

Security, access and ownership

☐ Do we own all code and IP the engineers produce?
☐ Will you sign our NDA before sharing profiles?
☐ Will engineers work only in accounts we control, with access we can revoke?
☐ Which security and compliance standards have your engineers worked within?

Cost

☐ What is the monthly cost per engineer by seniority, and what is included?
☐ What would change the cost during the engagement?
☐ How do you quote a team with mixed roles and seniority?

2. Red flags and what they usually mean

Red flag	What it usually means	What to do
Will not show profiles until you commit	They do not have the engineers yet and will recruit after you sign up	Ask for profiles of real, available engineers or walk away
Cannot describe their vetting beyond "rigorous"	Light screening or resume matching	Ask for a vetting report and the pass rate
Senior rates quoted far below market	Seniority is overstated, or engineers will be shared across clients	Interview the engineers on senior-level problems
Hours described as "flexible"	Little real-time overlap with your team	Ask for exact hours in your time zone, in writing
No reachable references for similar work	Limited relevant experience	Ask for two references with a similar stack or scale
Account manager is your only contact	Problems reach engineering leadership slowly	Ask who owns delivery quality and meet them

3. Reference call script

#	Question	Listen for
1	What did the engineers from this vendor work on, and for how long?	Similar scope and a meaningful duration
2	How did their seniority compare with what was promised?	Specific examples, not general praise
3	Tell me about a time something went wrong. How did the vendor handle it?	Speed, ownership and a fix, not blame
4	How well did the engineers work with your team day to day?	Standups, code review and communication without friction
5	Did anyone need to be replaced? How did that go?	Fast replacement with handover
6	Would you use them again for the same kind of work?	A clear yes, ideally with evidence of expansion

How to use this checklist

Before the first call, write down the roles, seniority, stack and working hours you need. Vendors answer better when the need is specific.
Send the question list ahead of the call and ask for written answers on vetting, hours, replacement and cost.
On the call, focus on the questions they answered vaguely. Specific follow-ups expose weak processes quickly.
Ask for profiles of real, available engineers and interview at least two with your own technical questions.
Check the red flags table against everything you heard. One serious red flag is enough to stop.
Run the reference script with two clients who used the vendor for similar work.
Score the shortlisted vendors on the vendor evaluation scorecard and decide.

Example: strong vs weak answers

Question	Weak answer	Strong answer
What hours will they work?	"Our engineers are flexible and overlap with US hours."	"9 a.m. to 6 p.m. Eastern, so they join your 9:30 standup and review PRs the same day."
How do you vet engineers?	"We have a rigorous multi-step process."	"Recruiter screen, structured technical interviews, a system design session and recruiter review. Only a small share of the candidates we interview pass."
What if someone is not the right fit?	"That rarely happens."	"Tell us, and we replace the engineer and handle the handover."

Common mistakes when choosing a staff augmentation vendor

Choosing on rate alone. Compare cost at the seniority you need, then judge the engineers.
Skipping your own interviews. A vendor's vetting does not replace your judgment of fit with your codebase and team.
Accepting vague hours. Overlap decides whether code review and incident response happen the same day.
Not planning onboarding. Augmented engineers need the same access, context and onboarding as anyone else on the team.
Treating augmented engineers as outsiders. Engineers who join your rituals and report to your leads ship faster than a separate team behind a ticket queue.

Ask Ryz these questions

We welcome this checklist. Ryz senior engineers work on your team, reporting to your leads, on US business hours including New York hours. Only the top 1% of the tens of thousands of engineers we interview make it, and we share profiles of real engineers before you decide. You own all code and IP, and engineers work in accounts you control. Typical cost is $7,000 to $15,000 per engineer per month by seniority. Read about our staff augmentation and vetting process, or talk to us to scope your team.

FAQ

What questions should I ask a staff augmentation company?

Ask how they vet engineers and how many pass, whether you can see and interview the specific engineers, what hours they work in your time zone, how replacement works, who owns the code, whether they sign your NDA, and what each engineer costs per month by seniority.

How do I evaluate a staff augmentation vendor's vetting?

Ask for the stages, who runs them and the pass rate, and request an anonymized vetting report. Then interview two of their proposed engineers yourself with problems from your own codebase. If the engineers do not match the described bar, the process does not either.

What are red flags in staff augmentation?

No profiles until you commit, vague vetting, senior rates far below market, "flexible" hours without specifics, no references for similar work and no clear owner of delivery quality on the vendor side.

Should augmented engineers report to my engineering leads?

Yes, for most teams. Engineers who join your standups, work in your repos and report to your leads integrate faster and share context with the rest of the team. A vendor account manager should handle support, not day-to-day direction.

How much does staff augmentation cost?

It depends on seniority and role. Ryz is typically $7,000 to $15,000 per engineer per month, mostly mid-level to senior. Our rates pages break down costs by role.
