Senior/Principal Materials, Structures & Thermal Engineer
Advanced Defence Aerospace Programme
About the Opportunity
We are working with an innovative and well-funded engineering organisation operating within the advanced defence aerospace sector, developing next-generation high-speed aerial systems for national security applications.
This is a rare opportunity to join a highly experienced engineering team at an early stage of a major development programme. With funding secured and a clear technical roadmap established, the team is progressing a new flight vehicle through concept development, design, analysis, manufacture and testing.
As a senior member of the engineering team, you will have direct influence over technical decisions, programme direction and product performance. The environment offers significant autonomy, close collaboration with technical leadership, and the chance to help shape both the product and engineering culture from the ground up.
The successful candidate will lead activities across materials engineering, structural design and thermal analysis, supporting the development of cutting-edge aerospace systems designed for challenging operational environments.
Key Responsibilities
Materials Engineering
- Lead material selection activities for aerospace structures and components.
- Balance performance, manufacturability, cost and supply-chain considerations.
- Develop and maintain material property databases to support engineering decisions.
- Work closely with suppliers on sourcing, evaluation and material qualification.
- Define and oversee quality assurance processes for materials and manufactured components.
Structural Engineering
- Lead structural design activities from initial concepts through detailed design.
- Perform structural sizing, stress analysis and margin of safety assessments.
- Develop analytical models ranging from first-principles calculations to advanced finite element analysis (FEA).
- Support design reviews, trade studies and architecture decisions.
- Validate structural performance against design requirements and test data.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Thermal Engineering
- Lead thermal modelling and analysis activities across the vehicle.
- Assess heat transfer, insulation strategies and thermal management approaches.
- Develop thermal models to support both conceptual and detailed design decisions.
- Correlate analysis with test results and operational requirements.
- Contribute to the development of robust thermal protection solutions.
Leadership & Programme Support
- Present technical findings to senior stakeholders.
- Mentor and support less experienced engineers.
- Contribute to future technology roadmaps and product development strategy.
- Ensure engineering work meets quality, safety and security requirements.
- Support multidisciplinary design reviews and programme milestones.
Essential Experience
- Degree (or higher qualification) in Aerospace Engineering, Mechanical Engineering, Materials Science, or a related discipline.
- Significant industry experience in materials, structures and/or thermal engineering within aerospace, defence, space, advanced manufacturing or another high-integrity engineering sector.
- Strong understanding of the full engineering lifecycle, from concept development through detailed analysis and validation.
- Experience using FEA tools such as ANSYS, Abaqus, Nastran or equivalent.
- Expertise in structural analysis, material selection and engineering substantiation.
- Thermal analysis experience, including heat transfer modelling and thermal management.
- Strong first-principles engineering skills and analytical problem-solving ability.
- Excellent communication skills with both technical and non-technical audiences.
- Right to work in the UK.
- Eligible to obtain UK Security Clearance (SC).
