Founding AI Engineer - AI Agents - London - £120k-£150k + Equity A venture-backed AI startup is looking for a Founding Engineer to help build a next-generation agentic AI platform transforming how billions are deployed into clean energy infrastructure. This is a true zero-to-one opportunity, working directly with experienced founders to architect systems that automate complex, high-stakes decision-making. You'll design and build advanced AI systems including knowledge graphs, multi-agent orchestration, evaluation frameworks, and self-improving AI pipelines. This role goes far beyond prompt engineering, you'll operate as a systems architect, working across LLM orchestration, context engineering, vector databases, and scalable cloud infrastructure. The stack includes Python, FastAPI, React, AWS, PostgreSQL, and Neo4j, with a strong focus on agentic architectures and production-grade AI systems. This is a rare chance to join at the ground floor with meaningful equity, shape the technical vision, and work on frontier AI problems in a domain that genuinely matters. If you're someone who thrives on ownership, operates with high agency, and is obsessed with where AI is heading next, this is built for you. Apply with your CV via the process and Nathan Laidlaw at Transparent Technology will be in touch.
