Why it matters

The role owns the foundation for an AI platform connecting trusted industry data to agents, including retrieval, routing, tool use, evaluation and observability. It offers broad responsibility across agent architecture, backend systems and infrastructure in a founding-stage team with active customers.

About the job

🚀 Founding AI Platform Engineer

📍 London | Onsite

💰 Competitive + Founding Equity

We’re working with an early-stage AI company building infrastructure that connects trusted industry data with AI agents, initially focused on renewable energy.

They already have paying customers and meaningful revenue and are now hiring a Founding AI Platform Engineer to help build the technical foundation alongside the founders.

You’ll own 👇

Production AI agent architectures — RAG, retrieval, routing & tool use
Backend systems and APIs powering the platform
Evaluation, observability and reliability of AI systems
Developer tooling, CI/CD and AI-native engineering workflows

Looking for 🧠

Strong Python/backend engineering experience with hands-on production experience building LLM agents, RAG or AI-powered systems. You should be comfortable working across backend, AI and infrastructure rather than sitting in one narrow lane.

Stack ⚙️

Python • FastAPI • PostgreSQL • Temporal • LLM Agents • RAG

Why join?

Genuine founding-level ownership, direct access to the founders, active customers, meaningful equity and backing from Visionaries Club + Google DeepMind leaders.

If you want to build an AI platform from the foundations up rather than join after all the interesting decisions have been made, drop me a message.
