About us

Founder-led, and proud of it.

OpenSource was built by a former software developer and a seasoned recruiter who have sat on both sides of the hiring table. We embed with your team to hire some of the brightest minds in tech, product and data.

George

Co-founder · Former software developer

George spent years as a software developer before co-founding OpenSource. Having been the person on the other side of the technical interview, he runs the technical screening that means clients only meet engineers who can genuinely do the job. He writes our engineering-hiring and salary research from that first-hand perspective.

Why we started OpenSource

We built OpenSource because we had both seen how badly technical hiring is usually done. One of us was the engineer on the other side of the interview, watching good people get filtered out by processes that did not understand the work. The other spent years in recruitment, watching agencies fire over CVs and hope something stuck. We knew it could be better, so we made the technical screen the centre of everything: every candidate is assessed by us, people who have done the job, before they ever reach a client.

That one decision changes the whole experience. Clients stop wasting interview time on people who cannot do the work, and candidates get a process run by someone who genuinely understands what they do. We stay deliberately hands-on and embed with the teams we hire for, because good hires come from real relationships, not transactions. It is why clients keep coming back, and why we can move fast enough to land the people everyone else is chasing.

FAQ

About OpenSource, answered.

Is OpenSource a recruitment agency or a software company?

A recruitment agency. OpenSource is a founder-led technology recruitment agency based in London that finds and places software engineers, product managers, data specialists and technology leaders. The name refers to how we work, openly and with the people who do the job, not to open-source software, and we do not make or sell recruitment software.

What makes OpenSource a technical recruiter rather than a generalist?

One founder was a software developer and interviews every engineer personally before a client sees them. Shortlists come with a written technical summary, and we turn down roles outside technology, product and data because we cannot screen them to the same standard.

Who runs the searches at OpenSource?

The founders. There is no sales team handing briefs to junior consultants. The person who takes your brief screens the candidates, manages the offer and stays in touch through the notice period.

Where is OpenSource based and where does it recruit?

Aldwych House in central London, with searches run across London, Berlin, Amsterdam and New York for startups and scale-ups, plus remote and hybrid roles for companies headquartered in those cities.
