03How we vet
You only interview people we would hire ourselves.
Technical depth
A working interview on the substance of the role, not a quiz on syntax.
A live build
A work sample or build task, so the skill is demonstrated rather than described.
Communication
English fluency, and the ability to explain a decision to people who did not make it.
Identity & references
Verification and reference checks, so the person you interview is the person who starts.
04Common questions
LangChain Developer, answered.
Do we have to use LangChain?
No, and a good engineer will tell you when the framework is adding more abstraction than value. Ask them where they would drop to plain API calls.
Can they migrate an existing prototype to production?
Yes. Moving from a notebook prototype to something observable and testable is the most common version of this brief.
How quickly can we start?
Most teams see an interview-ready shortlist within 48 hours to 3–5 business days, and finalise a hire within one to two weeks. The pace mostly comes down to how quickly you can review profiles and run interviews.
What does it cost?
Dedicated talent starts from $1,499/month per hire and scales with seniority and whether the role is part-time or full-time. Direct-hire placement is a one-time fee from 15% of first-year salary. Both are quoted in writing before you commit, with no upfront cost and no setup fee.
What if the hire is not right?
Dedicated hires carry a two-week risk-free trial and a free replacement within 90 days. Direct-hire placements carry a replacement window of 60 to 180 days depending on seniority. The full terms are on our Refund Policy page.
