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. A PhD

in heat transfer or a closely related field is ideal. 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

Essential

• Masters Degree or higher in Mechanical Engineering, Thermal Sciences, or a related

field.

• Depending on role from 3 years of combined academic and industry experience

• 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 modelling.

• Familiarity with data-driven methods and machine learning applications in thermal

analysis.

• Strong analytical, communication, and technical documentation skills.

Desirable

• PhD in Mechanical Engineering, Thermal Sciences, or a related field with

specialisation in heat transfer.

• 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)

Space Industry Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK space‑sector hiring has shifted from pedigree‑first screening to capability‑driven evaluation across the full stack—spacecraft systems, payload/RF, flight software, GNC/ADCS, propulsion, structures/thermal, AIT (assembly–integration–test), mission/ground operations, reliability/radiation, and compliance (ECSS, export control). Employers want proof you can build, test, operate and scale space systems safely and economically. This guide explains what’s changed, what to expect in interviews & how to prepare—especially for satellite/spacecraft engineers, payload & RF/MM‑wave, flight & ground software, GNC/ADCS, power/thermal, AIT/test, mission ops, data/EO, and space product/TPM roles. Who this is for: Systems engineers, payload/RF engineers, flight software & FDIR, GNC/ADCS, power/thermal/structures, propulsion, AIT/test, reliability/radiation, QA/compliance, ground segment/cloud, mission operations, EO/data processing, and product/programme managers targeting roles in the UK space ecosystem.

Why Space Careers in the UK Are Becoming More Multidisciplinary

The UK’s space sector is growing fast — from satellite systems and Earth observation to satellite communications, space robotics, propulsion, space data analytics, and mission operations. But the nature of space work is changing. Projects involving satellites, launch systems, space robotics and ground infrastructure are now embedded in regulation, public perception, human interaction and cross-disciplinary design. Space careers in the UK used to be dominated by engineers, astrophysicists, systems analysts and telemetry experts. Today, they increasingly demand fluency not only in aerospace, software, electronics & data, but also in law, ethics, psychology, linguistics & design. After all, space systems operate under treaties, privacy constraints, public scrutiny, international collaborations and human interfaces. In this article, we explore why space careers in the UK are becoming more multidisciplinary, how those allied fields intersect with space work, and what job-seekers & employers must do to thrive in this evolving cosmos.
