Senior Optimisation Engineer

Role overview Own the optimisation models that help data centres maintain reliable power when grid connections are subject to curtailment. The work spans battery sizing, curtailment-risk estimates, and live dispatch, with cooling systems also treated as a source of operational flexibility. You will guide how models are developed, validated, deployed, and explained to decision-makers.

Responsibilities - Improve battery sizing models that balance capacity choices against uncertain demand, prices, and network restrictions. - Build and calibrate curtailment forecasts using connection terms, network history, and live network-management signals. - Operate a rolling-horizon battery dispatch optimiser, updating decisions every few minutes and retaining required reserves. - Optimise participation across wholesale power, balancing, capacity, and local flexibility markets while accounting for battery degradation. - Incorporate cooling equipment and building thermal mass within comfort and operating constraints. - Translate model outputs into finance-ready figures, and establish model review, testing, and release practices.

Requirements - Deep experience in optimisation or power systems, with a track record of building models used to operate real assets. - Ability to explain and defend modelling choices in detail. - Relevant experience may include battery dispatch or trading optimisation, solver development, or energy and capacity optimisation. - Capability to lead model development across uncertainty, forecasting, and operational decision-making.

Benefits and work setup - Hybrid work, with remote flexibility for the right candidate. - Salary and equity, plus a learning and development budget.
