In an office, a tech lead can fix a bad plan by turning their chair around. On a remote team, the same correction takes a written comment, a design doc, or a call someone has to schedule across time zones. That changes who is good at the job. The best remote tech leads I've worked with wrote pull request comments you could read six months later and still understand why a decision was made. Several of them interviewed quietly.
If you're hiring a tech lead for a distributed team, screen for that.
Key Takeaways
- A tech lead guides one team's technical approach and execution. They are not a people manager.
- On a remote team, most leadership happens in writing: design docs, reviews, decision logs.
- Screen with real artifacts: a design doc exercise, a code review, and a written trade-off.
- A short paid trial on a real problem tells you more than another interview round.
What the Role Actually Is
Will Larson's description of the Tech Lead archetype is the clearest one I know: "The Tech Lead guides the approach and execution of a particular team," usually partnering closely with a single manager (StaffEng). That means owning the team's technical direction, breaking work down, unblocking engineers, and keeping quality up, while the engineering manager owns hiring, careers, and performance. If you haven't drawn that line yet, read tech lead vs engineering manager before you write the job description.
On a remote team, the tech lead also becomes the keeper of the written record. Fully remote companies tend to write their communication norms down for a reason: decisions that live only in a call are lost the moment the call ends. Our own take is in async-first distributed engineering teams.
What to Screen For
| Signal | Green flag | Red flag |
|---|---|---|
| Design writing | Short docs with options, trade-offs, and a recommendation | Long docs with no decision, or no docs at all |
| Code review | Comments explain why; blocking vs non-blocking is clear | Nitpicks, or rubber-stamp approvals |
| Scoping | Breaks a vague goal into shippable slices | Wants the full spec before starting |
| Unblocking | Answers async, sets default decisions with a deadline | Everything waits for a meeting |
| Hands-on work | Still ships real code, takes the hard tickets | Hasn't committed in months |
| Time zone | Several hours of overlap with the team they lead | Leads from a timezone with no overlap |
That last row is underrated. A tech lead who is asleep during most of the team's working day becomes a bottleneck no matter how good they are. See why timezone overlap is the number one remote hiring factor.
A Screening Process That Works Remotely
1. Written trade-off (async, 45 minutes). Send a real-ish problem from your domain: "We need to add multi-tenant billing. Here's the current schema." Ask for a one-page recommendation. You're reading for clarity and judgment.
2. Code review exercise (live, 45 minutes). Share a PR with a few real problems and a few style quibbles. Ask them to review it out loud and in writing. Good leads find the bug, skip the bikeshed, and write comments a junior engineer can act on. Code review at a distance covers what good looks like.
3. Design conversation (live, 60 minutes). Walk through their written recommendation. Push on it. Watch whether they defend it with reasons or change it with reasons; both are fine.
4. References focused on writing. Ask former teammates: "Can you remember a design doc or review comment of theirs? What happened after?"
Then, if you can, run a short paid trial. Give the candidate one week on a real, bounded problem with one of your engineers. Do paid trial projects work covers when trials are worth it and how to keep them fair.
A Concrete Version
A 15-engineer SaaS company has a team of five distributed across Chicago, Bogota, and Lima. The team has no tech lead. The engineering manager is doing the technical calls, badly, because she's also running hiring for two other teams.
The CTO hires a senior engineer as tech lead. The screen uses the four steps above. One strong candidate produced a polished whiteboard session but a written trade-off that never picked an option. Another wrote a crisp one-page recommendation for billing with two options, the risks of each, and a clear pick, then reviewed the test PR with three comments, one of which caught a race condition the team had missed in production.
The second candidate gets the job. In the first 60 days, she introduces a one-page design doc template, a weekly async decision log, and a rule that any blocking review comment includes a suggested fix. The engineering manager gets her afternoons back. Cycle time drops because questions stop waiting a day for a meeting.
The Honest Counterpoint
Promoting from within is often better than hiring a tech lead from outside. An engineer who already knows the codebase and the people starts with credibility that an outside hire needs months to earn. If you have someone close, try them in the role first.
And a remote tech lead can't fix a team with no manager, no roadmap, or no product owner. If the real problem is that nobody decides what to build, a tech lead will spend their time filling that gap and burn out doing a job they weren't hired for.
Frequently Asked Questions
Should a tech lead still write code?
Yes, a meaningful amount. A tech lead who stops coding loses touch with the codebase and the team's pain. Many teams aim for a tech lead who takes the hard tickets but not the most tickets.
Can a contractor be a tech lead?
Yes, if they're embedded full-time in your team and you give them real decision rights. It works less well if they rotate across multiple clients.
How is a tech lead different from a staff engineer?
A tech lead focuses on one team. Staff engineers often work across teams on broader problems. See how to hire a staff engineer.
The Bottom Line
Hire a remote tech lead on the strength of their writing, their reviews, and their overlap with the team. Test with real artifacts and a short trial. Ruzora sends a vetted shortlist of senior engineers within 72 hours, all with 5-7 hours of overlap with US time zones. See available engineers or read how we vet.
Roberto Espinoza is CEO of Ruzora, which helps US startups hire pre-vetted senior LATAM engineers, with a vetted shortlist in 72 hours. See available engineers.
