Description du poste

Senior Mechanical and Thermal Engineer – Space Sector

Location : Paris, France (On-site)

Employment Type : Full-Time, Permanent

Salary : €70,000 – €80,000 + Benefits

Introduction :

A pioneering company at the forefront of space propulsion technology is seeking an experienced Mechanical and Thermal Engineer to lead the design and validation of mechanical and thermal systems for next-generation ion thrusters. This is a rare opportunity to join a fast-paced, innovation-driven environment developing a disruptive solution for small satellite propulsion.

The Opportunity :

You’ll play a critical role in a high-impact space program, working hands-on with a tight-knit team of engineers. You’ll take full ownership of mechanical and thermal architecture, drive technical decisions, and lead a small team of engineers in turning groundbreaking research into space-ready hardware. The role includes end-to-end responsibility, from concept design to in-orbit readiness.

Key Responsibilities :

• Define mechanical and thermal architectures for ion thruster systems.
• Conduct and supervise mechanical and thermal simulations (FEA, heat transfer, vibration).
• Select materials and solutions suited for space environments (vacuum, radiation, vibration).
• Oversee CAD design, technical drawings, and manufacturing activities.
• Manage supplier relationships and prototype builds.
• Lead the mechanical / thermal team, mentor engineers, and serve as the technical authority.
• Produce high-quality technical documentation, including test reports and justification files.
• Coordinate assembly, integration, and environmental testing (thermal / vacuum / vibe).
• Contribute to project milestones such as PDRs, CDRs, and TRRs.

Essential Skills and Experience :

• Master’s or PhD in Mechanical, Thermal, or Aerospace Engineering.
• 7+ years of experience in mechanical and thermal systems, ideally within the space industry.
• Strong knowledge of CAD tools (e.g. SolidWorks, CATIA) and FEA / simulation software (ANSYS, Abaqus).
• Familiarity with ECSS or NASA standards and environmental test campaigns.
• Proven ability to lead technically, communicate clearly, and mentor junior engineers.
• Experience in agile or start-up environments.
• Knowledge of ion propulsion or satellite subsystem integration.

Eligibility :

Applicants must have the right to work in the EU and be willing to work full-time on-site in Paris.
