Job Description

Full-Stack AI Engineer | Agentic AI | London / Remote | Contract or Permanent - £800 p/d or £150k per annum 

An early-stage AI company is building cutting-edge agentic systems to remove critical bottlenecks in global energy infrastructure. Their platform replaces months of manual legal and technical analysis with high-precision AI outputs, unlocking faster investment into renewable energy projects at scale.

You’ll work directly with the CTO to build and scale agentic AI systems, combining deep AI engineering with strong product development. This includes designing RAG architectures, building AI sub-agents, developing human-AI collaboration interfaces, and creating pipelines that extract structured insights from complex, unstructured datasets. You’ll operate across Python, FastAPI, React, TypeScript, and modern AI tooling, with a strong focus on real-world, production-grade AI systems.

This is a high-autonomy, high-impact role where you’ll work on genuinely cutting-edge AI problems in a fast-paced environment. You’ll have the freedom to experiment, own architecture decisions, and build systems that directly contribute to solving one of the biggest challenges of our time.

Apply with your CV via the process and Nathan Laidlaw at Transparent Technology will be in touch.
