Platform Engineer

🚀 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.
