Founding Engineer Job Birmingham area,England UK,Software Development

Do you have experience working at an early-stage startup and want to do it again, properly this time?

Are you excited by real ownership, commercial impact, and building something genuinely category-defining?

Experience:

3-8 years (startup / founding engineer background preferred)

We're partnered with a pre-seed AI startup building agentic AI systems that radically improve how knowledge workers think, decide, and get work done. This is not another chatbot. This is an AI-native product being built from first principles by engineers from elite technical environments (e.g. Palantir, Citadel).

They're now looking for a Founding Engineer, someone who’s:

Already been a founding / early engineer or
Worked in a fast-moving, high-growth startup and understands what it takes to ship real product, fast, with users in mind
Has a generalist mindset
A strong mathematical background

You'll work directly on:

Core agent loops (prompting, tool selection, model choice, memory & context)
High-performance, real-time LLM-powered UX
Making autonomous systems reliable enough for daily, mission-critical work

As a Founding Engineer, you'll wear many hats:

Frontend: Type Script, React
AI/LLMs everywhere (Cursor/Copilot as a daily workflow)
Product thinking & UX judgment
Talking to users and rapidly iterating
Full SDLC ownership
; build, ship, break, fix, repeat

What they're looking for:

commercial & product mindset – you care about outcomes, not just code
Comfortable in ambiguity and zero-to-one environments
Proven ability to ship fast in small teams
AI-native way of working (LLMs are tools, not toys)
Resilient, adaptable, and genuinely excited by hard problems
Real ownership — technical and product
Small, elite team that ships fast
Well-funded with long runway
You'll help define a product shaping the next generation of software
Not another boring B2B Saas... this is something you'd actually use

If you're ready to step into a true founding-level role, influence the product direction, and build something genuinely new, this is the one. Interested?
