Hire Software Engineers

We help startups and scale-ups hire software engineers who can actually do the job. Every candidate is technically screened by us, people who have written production code, before they reach your team, so your interview time goes on genuinely strong engineers.

What we screen for

  • Fundamentals: data modelling, APIs, concurrency and testing that hold up in production
  • System design and the ability to reason about trade-offs out loud
  • Debugging under ambiguity on a realistic, messy problem
  • Operational judgement: observability, deploys and failure modes

Every candidate is technically assessed by us, people who have done the job, before you spend a minute interviewing.

FAQ

Hiring software engineers, answered

How do you screen software engineers?

Every engineer is technically assessed by us before you see them: a realistic work sample or pairing session over an abstract puzzle, scored against a written rubric rather than a gut feeling. We assess fundamentals, system design, debugging and operational judgement, so you only interview people who can genuinely do the job.

How quickly can you deliver a shortlist of engineers?

For most roles we come back with a technically screened shortlist within days, not weeks, because we screen candidates ourselves and maintain an active network of pre-vetted engineers.

What does it cost to hire a software engineer through OpenSource?

Three models: contingent (you pay only on a successful placement), embedded / RPO (a dedicated recruiter for hiring at volume) and retained search (for senior and business-critical roles). We recommend the right fit for your stage.
