Space Mechanical/Thermal Engineer (m/f/d)

Location: Foetz, Luxembourg
Type: Full-time

Maana Electric is seeking an experienced Mechanical / Thermal Engineer with a strong background in mechanical design of space-flight hardware. You will work on designing and qualifying equipment for lunar and deep-space environments, contributing to our mission to empower human exploration beyond Earth.

Your mission

As a vital member of our engineering team, you'll contribute to the development of cutting-edge technologies for In-Situ Resource Utilization (ISRU), turning raw space resources into essential metals and products to boost human space exploration.

Responsibilities

• Design, model, and develop mechanical and thermal systems for space-flight hardware (e.g. structural elements, mechanisms, thermo-mechanical assemblies, deployable systems).
• Perform thermal and thermo-structural analyses and simulations to ensure operation under lunar/space environment constraints (vacuum, large temperature swings, radiation, etc.).
• Build and iterate breadboards, prototypes and test articles from design to manufacturing to testing.
• Collaborate with interdisciplinary teams (mechanical, thermal, materials science, electronics, systems engineering) across all project phases.
• Select appropriate materials and manufacturing processes suitable for space conditions (e.g. vacuum-compatible, cryogenic or high-delta-T tolerant, radiation-resistant).
• Support assembly, integration and test campaigns (thermal vacuum, thermal cycling, mechanical loads, deployment tests).
• Assist procurement office in discussions with suppliers.

Qualifications

• Master's degree in Mechanical, Aerospace, Space Engineering or related fields.
• 3+ years of work experience (a PhD in a relevant applied research project may substitute).
• Strong hands-on experience designing and building mechanical systems, preferably for space or harsh-environment applications (lunar or Martian).
• High proficiency in CAD software (SolidWorks is mandatory).
• Proven competence in thermal and thermo-structural simulation; experience with tools such as ESATAN-Thermal and/or COMSOL Multiphysics is strongly desired.
• Fluency in English (verbal and written).

Preferred

• 5+ years in space projects, especially mechanism design, deployment systems or lunar/planetary hardware.
• Familiarity with ECSS, NASA GEVS and formal review processes (SRR, PDR, CDR).
• Hands-on experience with breadboards, prototypes or test articles through TVAC and mechanical testing.
