Lead Optimisation Developer

Lead Optimisation Engineer - Python / Pyomo / Gurobi

Fully Remote (UK) 2 Days in London Office per Month

Base Salary up to £60,000 + Performance Bonus

Are you a problem-solver who loves applying mathematical models to real-world optimisation challenges?

We're looking for a Lead Optimisation Engineer to take ownership of a core optimisation engine that drives intelligent routing and decision-making across a complex, data-driven platform.

This is an ideal next step for a 2nd-job engineer ready to move from supporting optimisation projects to leading them - with full exposure to product, architecture, and performance tuning.

What You'll Be Doing

• Designing, implementing, and maintaining MILP optimisation models using Pyomo and Gurobi/SCIP.
• Researching and prototyping new optimisation methods to improve runtime and solution quality.
• Managing API operations end-to-end - from schema design to orchestration and integrations.
• Refining methodologies including refill, extrapolation, benchmarking, and recosting.
• Reviewing and QA'ing code, running performance testing, and owning debugging cycles.
• Collaborating closely with product and engineering leads to prioritise features and manage technical debt.
• Engaging with stakeholders to troubleshoot and propose optimisation improvements.

What We're Looking For

• Strong Python skills and experience working with optimisation tools such as Pyomo, Gurobi, or SCIP.
• Solid understanding of mathematical modelling and problem-solving in real-world applications.
• Comfort working with APIs, backend data models, and performance monitoring tools.
• A proactive mindset - someone who enjoys owning technical challenges from concept to delivery.

What's on Offer

• Fully remote working (UK-based) with just 2 days per month in the London office.
• Base salary up to £60,000 p.a. + performance bonus.
• Opportunity to lead and scale a core decision-making engine that impacts real business outcomes.
• Supportive, collaborative team culture that values innovation and continuous learning.

Apply now if you're ready to make the leap from contributor to technical lead - with full ownership, autonomy, and measurable impact.
