Some roles give you a better salary. Some give you a better story. This one has the potential to do both. I’m hiring multiple Principal Software Engineers for a Series A Scale Up in Central London that is moving quickly, building with AI as a real part of the product, and led by people who know how to scale.
The leadership team has a strong track record of building products users genuinely want and scaling businesses through serious growth, including journeys that have reached tech unicorn level. That matters, because for the engineer joining, this is not just about the tech. It is about being part of a company with real product instinct, real ambition and a genuine chance of becoming a major success.
You’d be joining a team where engineers stay close to the product, work on meaningful problems, and have room to influence. It is a strong fit for someone who wants modern tooling, true ownership, visible impact and the chance to grow with a business that has huge momentum behind it.
On the technical side, they are interested in engineers with strong experience building modern web products. React and TypeScript are the key front end areas. On the backend, they are open to backgrounds across Node.js, Python, Java, Go or C#. Experience with APIs, cloud platforms, performance, scale and strong product engineering judgement will all be useful.
What they want to see:
- Strong experience building software in product focused engineering teams
- Good React and TypeScript capability
- Backend experience across one or more of Node.js, Python, Java, Go or C#
- Engineers who enjoy pace & ownership + being close to product decisions
- Interest in AI-enabled software development and modern engineering workflows. Agentic coding experience is preferred - Claude Code, Cursor, Codex...
A few practical points:
- Office is based in Kings Cross
- It is best suited to people who enjoy the pace of a scaling startup + product focused engineering
Package: £120,000 to £140,000 + stock options
