Founding Machine Learning Engineer - AI Start-Up (On-Site | Equity + Salary)

A rare opportunity to join one of London’s most exciting AI start-ups at the ground level! Backed by top-tier investors and led by a world-class founding team from Oxford, Cambridge, and Imperial, this company is pushing the boundaries of applied AI.

They’re now looking for a Founding Machine Learning Engineer to join the core technical team and lead the development of their ML systems from the ground up.

About the Company:

Founded by experienced operators with multiple AI start-up successes under their belts, this venture is already attracting serious attention. With strong financial backing and a bold technical vision, they’re building intelligent systems that solve high-impact real-world problems.

This is not just another AI start-up - it’s a company where cutting-edge research meets practical, scalable product development.

The Role:

As a founding ML engineer, you’ll be deeply involved in shaping the entire ML pipeline - from research and prototyping to model deployment and optimisation. You’ll work closely with product and engineering to integrate intelligent features into a user-facing product from day one.

You’ll need to be both a scientist and an engineer: excited by innovation, and pragmatic about delivering impact!

• Python and modern ML libraries (e.g. PyTorch, TensorFlow, JAX)
• AWS and cloud infrastructure for scalable training and inference
• ML ops tooling, model monitoring, and data pipelines
• Bonus: experience with LLMs & generative AI is a strong plus

What They’re Looking For:

• Top-tier academic background in Computer Science, Engineering, Maths or a related field – Oxbridge, Imperial, or equivalent
• 4+ years of hands-on ML experience, ideally in fast-moving start-up environments
• A strong track record of building and deploying ML models into production
• Solid understanding of ML system design, experimentation, and model evaluation
• Experience working with ambiguous product requirements and iterating fast
• Passion for pushing boundaries in AI - and for building real products, not just prototypes
• Happy working 5 days/week on-site in a Central London office, shoulder to shoulder with the founding team

What’s on Offer:

• Exceptional salary
• Meaningful equity - founding engineer-level stake
• Ownership of the ML roadmap and long-term technical vision
• The chance to help build a product and company from day one
• A deeply collaborative, high-performance environment with elite peers

If you're an experienced ML engineer looking for your next big challenge, and want to build something important with world-class people - this could be the opportunity of a lifetime!
