Job Description
I’m supporting an early-stage AI startup building genuinely transformational tooling for some of the most document-heavy industries out there.
They’re now looking for a Senior or Staff Software Engineer who wants to design and ship AI-driven product capabilities end-to-end, from the first customer conversation all the way to production rollout and adoption.
What you’ll be doing
Owning core product components from concept → architecture → build → deployment → customer adoption
Designing scalable systems for data extraction, workflow automation, document analysis and multi-step content
Using tools like Cursor, Copilot, and Claude Code to move fast and focus on high-level engineering decisions
Collaborating with customers and internal teams to understand real business problems
Implementing secure-by-default, privacy-first approaches
Staying close to research and continually experimenting with new AI techniques
Mentoring engineers and helping shape engineering best practices
About you
Strong Python engineering background with a track record of shipping real product features
Experience in high-growth, fast-moving environments
Confident designing and maintaining APIs and integrations
Comfortable working end-to-end across architecture, coding, deployment and customer delivery
You think like a product engineer, working in tight loops, understanding the “why,” and focusing on real user value
You use AI coding tools as leverage rather than novelty
Curious, honest, quick to dive deep, and not afraid to challenge assumptions
Strong communicator who can explain complex ideas clearly
Ambitious, resilient, and motivated by solving genuinely tricky problems
What’s on offer
£100k–£150k salary
Meaningful equity
Unlimited annual leave
Enhanced pension
£100 monthly wellbeing budget
£1000 annual L&D budget
Strong parental leave package
