Calibre is an AI-native startup founded by ex-Palantir engineers that recently raised a $3.3M pre-seed round to transform the £190B certification industry.
Join Calibre as a founding full-stack engineer to dismantle the archaic £190B TIC industry. Working alongside ex-Palantir founders, you will build AI-native agentic systems that replace manual document checks and Excel with automated audits. This role offers extreme ownership and the chance to apply the Palantir playbook to a foundational global market.
Why this role is remarkable:
- Work directly with two ex-Palantir technical co-founders to master the “FDE playbook” for deploying complex AI workflows in enterprise settings.
- Join a well-capitalized team with a $3.3M pre-seed from top-tier San Francisco VCs targeting a broken £190B global industry.
- As a founding engineer, you will have total architectural ownership and influence, shipping critical code to real-world customers from day one.
Responsibilities:
- Develop high-velocity, full-stack code across front-end, back-end, and sophisticated AI-agent infrastructure using tools like Claude Code and Cursor.
- Collaborate with founders to solve architectural challenges, specifically capturing human “tribal knowledge” into self-improving, agentic AI systems.
- Engage directly with design partners to translate complex manual certification processes into intuitive, automated digital solutions that solve real-world problems.
Qualifications:
- A top-tier programmer with 0-3 years of professional experience and a strong first-principles computer science background from a top university.
- AI-native developer who treats LLMs as a force multiplier and understands how to build robust frameworks around their inherent weaknesses.
- Language-agnostic problem solver with a portfolio of high-quality personal projects or hackathon wins that demonstrate exceptional technical talent and high output.
