Staff Engineer

Level: 5

Role Type: Permanent or Contract

Location: Hybrid - work on site in our London office 3x/wk

The Mission

Our platform is transforming life sciences automation. It already saves lives — but our next challenge is scaling it globally, with optimisation and data at its core.

This is your chance to work on some of the hardest automation engineering problems in optimisation and machine learning, with direct impact on how scientists and engineers across the world operate. The algorithms you design won't sit in theory — they'll power real-world decisions that affect human health outcomes.

The Role

As a Staff Engineer for ML, Data & Optimisation, you'll be both a hands-on contributor and a technical leader influencing direction. You'll work in a senior engineering team alongside product managers, shaping how optimisation, data, and machine learning are applied at scale.

You'll bring ideas — from solver tech to heuristic approaches — and the ability to turn them into scalable, production-grade systems.

What You'll Do

Design & Implement Optimisation Solutions: Build high-performance algorithms using or-tools, solver technology, and custom approaches.

Balance Rigour & Practicality: Apply exact methods where needed, and heuristics where scale and performance demand it.

Productionise Your Work: Use Python and container tech to move from prototype into scalable production system.

Collaborate Deeply: Work within a multidisciplinary team (engineering, design, PM) to align optimisation solutions with product goals.

Experiment & Innovate: Bring forward new ideas, approaches, and techniques to stay ahead in the optimisation/ML space.

Influence Direction: Shape the strategy for how ML and optimisation underpin the global scaling of our product.

What You Bring

Strong experience with or-tools, solver technology, or custom optimisation methods.

Deep understanding of ML and heuristics in optimisation strategies, and when to apply them.

Proficiency in Python, with ability to structure clean, maintainable solutions.

Experience with containerisation (Docker/Kubernetes) and deploying scalable ML/optimisation pipelines, or willingness to learn.

A track record of solving complex optimisation problems in startup, scaleup, or high-performance contexts.

Curiosity, creativity, and the ability to generate and test many ideas quickly.

Nice to Have

Broader ML/data engineering experience.

Exposure to high-volume or real-time systems.

Experience in mission-critical industries (e.g., healthcare, logistics, manufacturing).

Why Join Us

Work on hard technical problems that directly impact human health.

Be part of a senior engineering team, collaborating closely with PMs and designers.

Build solutions that go beyond prototypes — real-world production systems at global scale.

Hybrid working: 3 days in our London office, balanced with flexibility.

Competitive package, plus the opportunity to do career-defining, meaningful work.

If you're a staff-level engineer excited to turn ML, data, and optimisation into global-scale impact, this is the role you've been waiting for.
