Responsibilities

The Senior Aerothermal Engineer is responsible for the development, analysis, and validation of aerospace thermal management systems within the NPI and Sustaining team, using 1D modelling and simulation tools to predict component and subsystem performance across the operating envelope. The role applies aerothermal and thermodynamic expertise to deliver robust designs that meet performance, durability, weight, and efficiency targets.

The role defines modelling approaches, requirements, and design trade studies; leads model correlation with rig and engine/aircraft test data; and provides clear, data-driven recommendations to engineering and programme stakeholders. It also supports product verification and compliance, resolves complex cross-functional technical issues, and provides lifecycle support from concept through certification and in-service improvement.
