- Location
- Remote (United Kingdom)
- Compensation
- Equity-only
Are you ready to build the future of AI-driven work from the ground up? As a founding engineer at this pre-launch, privacy-first AI startup, you'll own the entire technical stack and architect a platform that unifies fragmented toolsets into one secure conversation.
This is a rare, equity-only opportunity for a high-conviction builder to define a company’s DNA and product vision before launch. If you’re a generalist who thrives on autonomy and wants to lead development on RAG, agents, and complex integrations, this is your chance to trade risk for founder-level influence.
