Founding AI Software Engineer (London Area)

Founding AI Software Engineer | Agentic AI | Stealth Start-up (VC-Backed)

London – Onsite | Equity Included

A stealth-mode, VC-backed start-up is building something entirely new at the intersection of LLMs, Agentic AI, and product-driven problem solving. Backed by Creandum (investors behind Spotify, Klarna, Neo4j, and Depop), this is a rare chance to join extremely early.

This team is growing its founding engineering group to help shape an LLM-leveraged platform that already has active customers and strong demand. With increasing traction and an ever-extending runway, they’re looking for those who want to go deep on applied AI.

What You’ll Do

• Work alongside world-class engineers to architect and scale AI-powered software from the ground up
• Build and refine agentic systems using LLMs. Whether you\’re coming from production deployments or personal explorations, your experience will matter
• Solve complex product and technical challenges in a hands-on, collaborative onsite environment
• Own end-to-end features in a modern stack: Python, TypeScript, React, Node.js

You Might Be a Fit If You…

• Have strong experience in software engineering and a passion for building from 0 to 1
• Have experimented with or built agentic AI systems (AutoGPT, ReAct, LangGraph, CrewAI, etc.)
• Are eager to work onsite in London with a highly driven and technical team
• Want to earn meaningful equity in a venture that is both well-funded and genuinely disruptive

This is a rare opportunity to join a company before the spotlight hits; building with autonomy, vision, and genuine innovation. If you’re excited by the future of agentic AI and want to shape it from the ground up, this is where you should be.
