Job description

MaiaSpace is a European space tech company, designing, manufacturing and operating competitive and sustainable solutions for space mobility. We are driven by the belief that access to space is a major enabler for a better and more sustainable life on Earth, addressing the challenges faced by humanity: climate, resources, connectivity, and data. Our aim is to successfully design and test a cost-effective and reusable mini-launch vehicle by 2026.

Cryogenic stage thermal engineer

We are looking for a thermal engineer to join one of our Cryogenic Stage Teams. Our teams design, manufacture and test the cryogenic stages.

You will be in charge of the determination of thermal environment to which the stage and its constituting sub-systems are submitted. The main focus will be the determination of thermal environment in stage and launcher cavities. You will also have the responsibility to size of the necessary thermal regulation systems: conditioning, thermal protections
 You will work in close collaboration with thermal engineer from other product teams with the possible support of experts.

Your tasks include all or a sub-set of the following based on your experience and abilities:

  • Contribute to the cryogenic stage development plan by identifying necessary activities to ensure the flight worthiness of our stages regarding thermal aspects whether they be simulations and/or tests
  • Define the necessary methods and tools in order to perform the required calculations whether they be analytical or numerical; or contribute to this activity
  • Benchmark, choose, purchase and support the installation of necessary numerical tools to perform required simulations; or contribute to these activities
  • Calculate the thermal environment (radiative, convective and conductive) in stage cavities or on stage structures during all flight phases whether they be on ground, in atmospheric flight or ballistic phases
  • Define test objectives, define measurement plans and identify necessary sensors, contribute to the elaboration of test campaigns, perform test predictions and test exploitations
  • Assess the compatibility of stage equipment to the thermal environment and in case of incompatibility propose solutions to solve the issues (design modifications, additional tests, reduction of calculation conservatisms)
  • Size thermal protections and determine possible thermal protection materials and technologies
  • Size conditioning systems
  • Support treatment of production anomalies on thermal regulation systems
  • Perform flight simulations and flight exploitations

Job requirements

🛾 Specific competences & abilities:

  • Strong knowledge and experience in thermal engineering, prior experience appreciated
  • Knowledge and experience of launch vehicles or aerospace/aeronautics vehicles is appreciated
  • Experience with thermal modelling tools
  • Experience with programming languages (Python, VBA)
  • Knowledge on thermal management and thermal protection technologies
  • English level sufficient to read and write technical documentation, to perform oral technical presentation and to interact on technical topics

🎓 Qualification:

Engineering degree (+5 years post-Baccalaureate) ideally specialized in thermal engineering

🎬 Working at MaiaSpace

You will be joining a friendly multi-disciplinary team, comprised of multi-skilled people, following Agile and Scrum methodologies. This means that your role and responsibility may evolve over time with varied assignments and challenges depending on priorities and competences. Your work will be hands-on and in close contact with the final product. We are open-minded, transparent, pragmatic, result oriented and people centric. Teamwork is at the heart of how we work together and our co-workers share the same fundamental values: respect, humility, reactivity and autonomy with a passion for technical excellence. Our newly acquired office space at La Defense is located within the heart of Europe’s largest purpose built business and commercial district with easy access to public transport.

Written and spoken communication is in French and English.
