AI Fullstack Product Engineers - Userled - 80-100K + Bens + Equity - London Hybrid (3 days in the office)

Userled is reinventing B2B marketing with Generative AI Marketing early stage start-up, helping enterprise teams reach high-intent buyers through hyper-personalised, multi-channel campaigns. We’re building an AI-first platform from the ground up, with LLMs powering everything from content generation to strategic recommendations.

We’re looking for hands-on AI Fullstack Product Engineers who’s excited to build, ship, and fully own production-grade AI features. You’ll have complete autonomy to design and launch intelligent agents, use cutting-edge LLM tools, and shape the future of our product in a role that’s all about real-world impact, not research for the sake of it. You’ll be deploying real features to real users, fast.

You’ll be responsible for architecting and shipping AI-powered features using tools like PydanticAI, LangGraph, FastAPI, and OpenAI/Anthropic APIs. You’ll build and orchestrate intelligent agents and RAG pipelines, moving quickly to prototype, test, and launch in days, not months. Working closely with product, design, and go-to-market teams, you’ll build features that solve real customer problems and contribute directly to our AI roadmap and long-term technical direction.

You might be a great fit if you’ve spent 5+ years in software engineering and have 1 - 3 years of experience building with LLMs. You know how to apply LLMs in production (not just in notebooks), and you’ve built agentic systems using orchestration frameworks like LangGraph or LangChain. Most importantly, you’re someone who wants true ownership, real autonomy, and to make an outsized impact, not just work through a backlog of tickets.

In return, you’ll get a competitive salary with meaningful equity, 25 days holiday plus public holidays, a top-spec Mac and remote setup budget, enhanced parental leave, access to our Shoreditch office and on-site gym, regular team off-sites, and a no-BS, high-trust culture that values speed, openness, and smart people doing great work.
