Job summary
We are seeking a highly skilled and experienced Senior Aerothermal Engineer with deep expertise in heat transfer and fluid dynamics. The ideal candidate will have a strong background in both numerical modelling and experimental validation, being able to conceptualise, model, design, build, test and analyse thermal components and systems. They will hold a PhD in heat transfer or a closely related field. Experience with machine learning applied to thermal problems and additive heat exchanger design is a significant advantage. This role requires a proactive team player capable of leading technical projects and mentoring junior engineers.
Your responsibilities
* Lead design and analysis of thermal components/systems, including heat exchangers, using advanced modelling tools (Ansys, OpenFOAM).
* Develop and implement heat transfer experiments, including rig design, data acquisition, and result interpretation.
* Apply machine learning methods to improve thermal performance modelling and experimental insight.
* Model thermal systems using Simulink and Simscape for dynamic performance prediction and control integration.
* Provide technical leadership across multidisciplinary teams on R&D and engineering projects.
* Oversee project timelines, deliverables, and coordinate with internal and external stakeholders.
* Contribute to the development of novel thermal management technologies, particularly in aerospace, energy, or automotive sectors.
* Assist in planning new projects and fundraising.
* Support and mentor junior engineers.
Selection criteria
* PhD in Mechanical Engineering, Thermal Sciences, or a related field with specialisation in heat transfer.
* Minimum 8 years of combined academic and industry experience (3–4 years post-PhD).
* Proficient in Ansys Fluent, OpenFOAM, or similar CFD platforms.
* Proven experience in heat transfer experiments and test rig development.
* Hands-on experience with Matlab Simulink and Simscape for system-level modeling.
* Familiarity with data-driven methods and machine learning applications in thermal analysis.
* Strong analytical, communication, and technical documentation skills
* Experience with additive manufacturing of heat exchangers.
* Background in project management (certifications like PMP are a plus).
* Prior team leadership or mentoring experience.
* Experience in regulated industries (e.g., aerospace, automotive, energy).
* Familiarity with Aerospace Standards (e.g. DO-160G)
