Hiring for Async First Engineering Cultures
Async first engineering cultures coordinate through written documents and asynchronous communication rather than meetings and real time chat. The engineers who thrive in this culture share specific traits. Strong writing. Self direction. Comfort with ambiguity. Willingness to surface blockers proactively. The teams that hire for these traits build async first cultures that work. The teams that hire on the same criteria as sync first cultures end up with engineers who suffer in the async environment.
What you actually need to know
- Async first needs different hiring criteria.
- Writing, self direction, and proactive surfacing are the key traits.
- Evaluate writing through actual writing samples.
- Onboarding is documentation heavy.
- Hiring on sync criteria erodes the async culture.
Trait
How to evaluate
Clear writing
Published work, take home doc, PR descriptions
Self direction
Past work without close supervision
Surfaces blockers proactively
Reference checks, past behavior
Comfortable with ambiguity
Interview questions about ambiguous situations
Picks up from documents
Onboarding observation
Works in their own time zone
Conversation about working style
Async communication preference
Self reported and shown in behavior
The core argument
Async first engineering cultures need different engineers than sync first cultures. The traits that matter shift. The hiring criteria have to match. The teams that ignore this build a sync first culture by accident even when they say they want async first.
The default coordination in async first is written. Decisions get made in documents that people read and respond to in their own time. Updates happen in writing. Meetings are rare and intentional. The pattern requires engineers who can produce clear written work product without the prompting of a meeting and who can pick up nuance from documents others have written.
The engineers who thrive share specific traits. Strong writing. The PR descriptions explain why. The design docs are readable. The questions in writing are precise. Self direction. The engineer can take an ambiguous problem and produce a proposal without being walked through it. Surfacing blockers proactively. The engineer writes when something is wrong rather than waiting for the manager to ask.
The engineers who struggle have the opposite defaults. They need synchronous meetings to feel productive. They write minimal PR descriptions and assume the reviewer will figure it out. They wait for the manager to ask before raising issues. None of these are character flaws. They are mismatches with the culture.
The evaluation has to match. Reading the candidate's writing tells you more about their fit than any verbal interview can. Past work on PRs they have shipped, blog posts they have written, design docs they have shared. The written work product is the strongest predictor of async first fit.

How much does this affect hiring
The hiring funnel is more selective. Roughly thirty to fifty percent of senior engineers who interview well in sync first cultures do not thrive in async first cultures. The selection criteria filter them out. The teams that maintain the discipline have async first cultures that work. The teams that lower the bar build sync first cultures by accident.
Features the hiring process must have
- A written work sample as part of the interview.
- Evaluation of past public writing.
- Reference checks that ask about written work product.
- A clear description of the culture in the job posting.
- Honest conversation about working style.
- Onboarding documentation tested with the candidate's profile in mind.
- A trial period that exercises async work.
- A clear path for the engineer to surface that the culture is not a fit.
Expert opinion
The async first culture is a real engineering choice with real hiring implications. The teams that hire on async criteria build async cultures that work. The teams that hire on the same criteria as sync cultures and hope for adaptation usually end up with sync cultures wearing async clothing. The discipline is to make the hiring criteria match the culture you actually want.

How this played out on a real project
A client wanted to build an async first engineering team. The first three hires were strong sync first engineers. The team kept defaulting to meetings. The async first culture did not take.
We changed the hiring criteria. The next three hires came from candidates with strong public writing and demonstrated self direction. The async behavior took root because the engineers defaulted to writing rather than to meetings. The culture stabilized.
The lesson was that culture follows hiring. The teams that hire for the culture they want build that culture. The teams that hire on different criteria build a different culture regardless of their stated intent.

Common mistakes teams make
- Saying async first but hiring on sync first criteria.
- No written work sample in the interview.
- No evaluation of past public writing.
- Onboarding that does not test the async fit.
- No clear culture description in the job posting.
- Mixing engineers from different culture defaults without explicit transition support.
- No trial period for the culture fit.
- Lowering the bar under hiring pressure.
A 30 day hiring process
- Week one. Define the async first culture in writing. Update the job posting.
- Week two. Source candidates. Evaluate their public writing.
- Week three. Interviews including a written take home.
- Week four. Reference checks focused on written work product. Decide.
