Senior Product Engineer - Up to £150,000 base + equity | Central London | AI-Native Startup
Do you want genuine ownership over what gets built, not just how you build it?
Are you already using AI as part of how you engineer software?
If so, keep reading.
Here’s the problem.
Audit and certification is a huge industry, but much of the work is still incredibly manual.
Auditors spend days gathering information, reviewing documents, writing notes and turning all of that into something usable.
This company is changing that.
They’ve built their own AI-powered technology to automate large parts of the process and are now using it themselves to deliver certification faster and more efficiently.
The ambition is significant: take audits that can traditionally take around 20 days and reduce them towards 7.
Why you should join:
- You’ll work directly with customers and decide what actually needs building
- You’ll own problems from initial conversation through to production
- You’ll join a tiny engineering team before significant growth
- You’ll help shape the product, architecture and engineering culture
- You’ll work alongside two founders who previously built AI solutions at Palantir
- You’ll have access to leading AI models and be encouraged to use them properly
- You’ll get meaningful equity while the company is still early
The engineering:
- Primarily Python + TypeScript
- Full-stack product engineering
- AI / LLM-powered products and tooling
- No obsession with one language or framework
- Pick the right technology for the problem
- Strong engineering fundamentals matter more than matching a checklist
They’re looking for engineers who are comfortable with ambiguity, enjoy solving problems from first principles and want significantly more ownership than you’d get in a traditional engineering environment.
Up to £150k base + equity, alongside a 5% matched pension, learning budget, MacBook Pro, access to AI models and opportunities for international travel.
5 days per week in Central London, around Aldgate / Whitechapel.
No need for an up-to-date CV. Apply for now and I’ll get in touch.
