Mechanical Design Engineer

We are building something ambitious in Luxembourg.

For our new entity, we are looking for a Mechanical Design Engineer ready to contribute to the development of advanced space transportation technologies and next-generation cryogenic systems.

You will work on enabling technologies that support the future of space mobility, from zero-boil-off cryogenic architectures to in-space propellant storage and transfer systems.

If you enjoy turning complex system requirements into robust, manufacturable hardware and want to grow within a high-technology, fast-evolving team, this role is for you.

Technology Focus

Our Luxembourg team contributes to cutting-edge developments including:

• Zero-boil-off cryogenic systems

• In-space cryogenic propellant storage

• Cryogenic fluid transfer in vacuum and microgravity environments

These technologies are key enablers for sustainable orbital operations and future deep-space missions.

Your Mission

As part of our Engineering team in Luxembourg, you will:

🔹 Design and develop 3D models and mechanical assemblies

🔹 Produce manufacturing-ready drawings (GD\&T, tolerances, material specs)

🔹 Contribute to mechanical architecture and system layout

🔹 Perform basic structural and thermal assessments (hand calculations \& FEA support)

🔹 Participate in design reviews and configuration management

🔹 Work closely with suppliers to ensure manufacturability

🔹 Support integration and test preparation activities

🔹 Maintain structured engineering documentation and PLM records

You will be directly involved in transforming innovative concepts into real, high-performance hardware.

Who We Are Looking For

Candidates must have the right to work in Luxembourg / EU at the time of application.

You are:

✔ MSc or BSc in Mechanical Engineering (or equivalent)

✔ 3–4 years experienced in mechanical design

✔ Strong in CAD (SolidWorks, CATIA, NX or similar)

✔ Comfortable producing detailed, production-ready drawings

✔ Familiar with structural design fundamentals

✔ Used to working in multidisciplinary technical environments

And above all:

You like hands-on engineering, you take ownership, and you enjoy solving real technical challenges.

Nice to Have

➕ Experience in cryogenics, aerospace, or high-performance systems

➕ Familiarity with ECSS standards

➕ Knowledge of vacuum systems, piping layouts, or thermal hardware

➕ Basic FEA experience

Why Join Us?

Because you want to:

• Work on cutting-edge space and cryogenic technologies

• Be part of a growing entity where your impact is visible

• Stay close to technical detail while developing your career

• Contribute to structured, high-quality engineering in a dynamic environment
