Senior Sizing Engineer (Cryogenic Tank)

We are looking for a Senior Sizing Engineer to join one of our agile multi-disciplinary teams in charge of the development of the Maia Upper Stage. In one of these teams, you will be in charge of the mechanical justification of pressurized and/or non-pressurized structures (mainly stainless steel) from the preliminary design to testing and flight worthiness justification.

Your tasks will be the following:

• Define sizing worklogics consistent with the maturity of the project and contribute to the overall stage development logic via identification of necessary tests
• Perform analytical or finite element analysis (static, buckling, dynamic) to support the design, optimization and justification of structures. Finite element analysis may be linear or non-linear.
• Ensure components meet performance targets, mass constraints, and other technical specifications
• Propose, define and manage mechanical test plans of subscale or full test specimens, participate to the tests in collaboration with the test team, exploit test results and update company knowledge database and stage mechanical justification accordingly
• Ensure the consistency between the hypothesis used for the mechanical calculations of the various structures of the stage
• Perform simulations, analyze their results, and combine load cases in order to be consistent with stage life phases during integration, transport or in flight.
• Calculation of local equipment loads using analytical or finite element models
• Justify stage bolted junctions
• Identify main contributors and perform sensitivity studies
• Write mechanical justification files
• Contribute to the treatment of production anomalies

🛸 Technical Skills:

• Strong knowledge and experience in structural mechanics
• Experience in finite element modelling and analysis (ideally HyperWorks & Optistruct, Nastran )
• Experience with programming languages (Python, VBA)
• Knowledge on metallic material properties and manufacturing processes (welding appreciated)

Interpersonal Skills:

• English level sufficient to read and write technical documentation, to perform oral technical presentation and to interact on technical topics

• Excellent communication skills and ability to collaborate effectively with multidisciplinary teams
• Ability to work autonomously and take initiative

🎓 Qualification:

• Education: Engineering degree in aerospace, mechanical, or a related field
• Experience: 5 to 10 years of experience in aerospace engineering or a related field

🎬 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.
