Machine Learning Engineer (LLMs)

Fully Remote | Up to £100,000 (DOE)

We’re working with a well-funded, early-stage tech company operating at the intersection of behavioural science and applied AI. They’re building intelligent, real-world AI products and are now looking for a Machine Learning Engineer with strong LLM experience to join their growing team.

This is a hands-on role where you’ll have real ownership, influence technical direction, and work closely with product and engineering teams.

What you’ll be doing

• Designing, building and deploying LLM-powered systems end to end
• Developing and optimising RAG pipelines, prompt strategies and workflows
• Working with GCP services, particularly Vertex AI
• Writing clean, scalable production code in Python
• Collaborating cross-functionally and clearly communicating technical ideas

What we’re looking for

• Strong experience with LLMs (this is a must)
• Solid Python engineering background
• Hands-on experience with GCP (Vertex AI)
• Experience building real-world ML/GenAI systems (not just experimentation)
• Excellent communication skills and ability to work autonomously in a remote setup

Nice to have

• Experience with RAG frameworks, vector databases, or orchestration tools
• Startup or early-stage environment experience

The details

• Fully remote
• Salary up to £100,000, depending on experience
• High-impact role with plenty of autonomy
• No visa sponsorship available

If you’re excited about LLMs, want your ideas to be heard, and enjoy building meaningful AI products, this is a great opportunity to make a real impact.
