Job Title: Full Stack Engineer

Salary: £60k-£80k + Equity

Company Description: Lichen AI - Early-stage agentic platform for AI discovery

Job Description:
As the first full-time engineer, you will transform a working prototype into a production-grade enterprise SaaS. You'll build robust backends, design intuitive interfaces for complex AI outputs, and establish foundational engineering practices. Working directly with an expert founding team, you'll ensure the platform is secure, reliable, and ready for global enterprise customers.

Location: Cambridge, UK

- Work alongside a world-class founding team including the former Chair of the UK Government’s AI Council and Amazon Alexa's speech recognition lead.

- Build a mission-driven platform that uses agentic AI to amplify human insight rather than replacing it, solving a critical adoption gap for enterprise clients.

What you will do:

- Transition a high-potential prototype to a production-grade platform by building secure, scalable backend systems and automated deployment pipelines.

- Lead the end-to-end development of the user interface, making complex AI-generated insights legible and actionable for non-technical business users.

- Implement enterprise-grade security and compliance standards including ISO 27001 and GDPR to ensure safe handling of sensitive client data.

The ideal candidate:

- Has 3-8 years of experience shipping production web applications using modern JavaScript/TypeScript (React) and Python (FastAPI).
