Job description

Astroscale France is looking for a Thermal Engineer to join the team at Toulouse, France.

We are a fast-growing company where you can expand on your experience and develop your skills further to enable your team to deliver amazing results. Your role will help us make a difference every day by ensuring the thermal team is well placed to drive forward our missions and help to make space safer and more sustainable for future generations.

Our Thermal Engineering team plays a key role in the design, analysis, and justification of our Rendezvous, Proximity Operations, and Docking (RPOD) space systems. You will regularly collaborate with the wider engineering teams to optimize the thermal architecture, conduct thermal analyses and testing activities, and contribute thermal expertise to the overall system design and verification process.

This role will be working as a Thermal Engineer as part of the Systems Engineering Group and means you will need to be able to:

• Understand the CONOPS and system constraints driving hot and cold cases.
• Engage with sub-systems and payloads to understand thermal constraints.
• Develop and maintain thermal models to appropriate levels of detail through the project lifecycle.
• Work with structure and MCAD to trade off thermal and mechanical constraints.
• Work with the AIT team to optimise thermal test set ups for validation and verification of thermal models and designs.

This role will therefore need a candidate who can understand both the analysis and the architecture, ensuring that system design and configuration meet the thermal requirements of our missions.

Responsibilities

• Capturing thermal requirements & constraints
• Support the development and architectural design of the Thermal Control System through thermal analyses.

• Producing and reviewing reports and technical documentation
• Working with a range of internal and external stakeholders
• Working as part of project teams through the full lifecycle from feasibility studies to testing, taking part in progress meetings and reviews
• Providing thermal inputs for business development activity

Essential Skills

• 2-5 years of commercial experience working as a thermal engineer of space systems, performing design and analysis
• Experience and knowledge of thermal analysis tools such as ESATAN-TMS / Systema Thermica
• Thorough understanding of design involvement in planning, executing and evaluating results from thermal tests
• Able to demonstrate technical leadership and work as part of a project team
• Professional level English – C1 minimum

Desirable skills

• University degree in physics, aerospace engineering or other relevant discipline,
• Knowledge of python, VBA, Matlab or batch scripting,
• Experience with CAD software such as Solidworks,
• As part of the thermal & mechanical team, you would be required to support the team depending on the opportunities. As such, experience in other engineering disciplines (mechanical, mechanisms, electrical) is a plus.
