Machine Learning Engineer – AI & Foundation Models (Future CTO Track)

West London | 3–4 days onsite

Up to £150k + equity

Company: AI StartUp

We’re hiring one of the first technical engineers for a pioneering AI startup building a foundation model that fully automates development.

This is a founding role with ownership over performance, scalability, and architecture across training and inference, working directly with the founders and evolving toward Head of Engineering / CTO.

You’ll work on:

• High-performance ML systems (training + inference)
• Building a novel ML model from scratch.
• Large models (e.g. transformers), latency & throughput optimisation
• Distributed systems and cloud deployment
• Internal tooling, benchmarks, and evaluation frameworks

Ideal background:

• Solid Python
• Deep ML systems optimisation experience (not just model training)
• PyTorch, large-scale inference, multi-GPU / multi-node systems
• HPC, embedded, or performance-critical environments
