Optimisation Engineer | Early-Stage AI Start-Up | London

Optimisation Engineer required to join an ambitious early-stage AI start-up in London, building intelligent systems to solve complex real-world operational problems.

You’ll take significant ownership of the company’s core optimisation technology, developing systems that make complex decisions dynamically as real-world conditions change. This is a highly technical role combining optimisation, algorithms, software engineering, and AI with the opportunity to see your work deployed into real operational environments.

You are:

3+ years of professional experience in applied optimisation, operations research, or a closely related field

Strong in Python with solid software engineering fundamentals

Experienced with constraint programming, mathematical optimisation, MIP, heuristics, or metaheuristics

Comfortable developing optimisation systems that operate under complex real-world constraints

Experienced taking technical or algorithmic systems beyond research and into production

Highly autonomous and motivated by solving difficult, open-ended problems

Bonus points:

Experience with CP-SAT, OR-Tools, or similar optimisation tooling

Experience with real-time or incremental optimisation

Experience with scheduling, routing, resource allocation, or similar optimisation problems

Experience combining machine learning / AI with optimisation

Previous experience in a high-growth start-up or similarly fast-moving environment

Why join:

Own a technically challenging and business-critical optimisation problem

Work at the intersection of optimisation, AI, and real-world systems

Take significant ownership over technical decisions and direction

See the technology you build directly impact real-world operations

Join a small, high-calibre team tackling genuinely difficult engineering problems

If you’re an Optimisation Engineer who wants to solve complex problems beyond simulations and see your work operating in the real world, I’d love to hear from you.
