Founding; Senior) Engineer | Early-stage

Founding Software Engineer | Six Figure Salary + Equity | London

I’m working with an early-stage technology company that is looking for a senior engineer to join at a genuinely formative stage of the business.

You’ll work directly with the founding team, have a significant say in how the product develops and take responsibility for turning ideas into production-ready software.

The company is tackling a complex problem sitting at the intersection of software engineering, data and AI, with a product that is already being used by customers and plenty of scope still to shape what comes next.

• 5+ years experience with React and Type Script
• Comfortable working across the backend, using Node.js, Python or similar
• A track record of taking ownership of significant product areas
• Experience in a startup, scale-up or similarly high-autonomy environment
• The ability to communicate clearly with both technical and non-technical people
• Experience with AI-enabled products, data-heavy systems or complex B2B software would be particularly interesting.

• Join while the engineering team is still small enough for your decisions to genuinely matter
• Work alongside founders who are deeply involved in the product and technology
• Help shape both the technical foundations and the product itself
• Get exposure to customers and understand the problems you're solving first‑hand
• Take on a broad engineering remit rather than being restricted to one part of a large system
• Meaningful equity with the opportunity to participate in the company's growth
