Working Student for Space Hardware Design & Thermal Simulation (m/f/d)

About Levion

Levion is a space technology company developing hardware to produce space-grown, high-quality semiconductor crystalline material for applications in radiation detection, medical imaging, and other high-performance sectors. Our flight-ready payload is targeting launch in 2028.

We are a small, high-output team working across the full development cycle — from system design and ESA review through to flight qualification. As we move from Preliminary Design Review (PDR) into Critical Design Review (CDR) preparation, we are looking for a hands-on working student to support our mechanical and thermal engineering workstreams.

What You Will Work On

• Creating and refining 2D technical drawings from existing SolidWorks models, including detail drawings for manufacturing and interface documentation
• Supporting the mechanical design finalization of flight-equivalent hardware components
• Maintaining and updating the Bill of Materials (BOM), including supplier and manufacturer research
• Documenting assembly logic and integration sequences in preparation for the EM2 build phase
• Supporting parametric design studies in SolidWorks as the design is refined toward CDR
• Assisting with basic thermal and process simulation tasks, such as parameter studies and geometry preparation for FEM analysis (Ansys)
• Contributing to technical documentation packages

What We Are Looking For

Required:

• Enrolled in a degree programme in Mechanical Engineering, Aerospace Engineering, Physics Engineering, Precision Engineering, or a closely related field (Bachelor's or Master's level)
• Practical experience with SolidWorks — you can create and modify 3D models and produce dimensioned 2D drawings independently
• Structured, detail-oriented way of working; able to manage tasks with limited supervision in a small team environment
• Good written and spoken English (our technical documentation is in English)
• Valid working permit for Germany/EU (no visa sponsorship)

Nice to have:

• Exposure to thermal simulation or FEM tools (e.g. Ansys, COMSOL, or equivalent) — even at a coursework level
• Interest in space hardware, vacuum systems, or high-temperature processes
• Experience reading or working with interface control documents (ICDs) or engineering standards (ISO, ECSS)

What We Offer

• Direct involvement in a real space hardware programme at a critical development stage
• Insight into the full engineering lifecycle — design, qualification, and flight preparation
• A small, technically ambitious team where your work has immediate impact
• Flexible working hours compatible with your study schedule (15-20 h/week)
• On-site in our VLAS premises

Diversity & Encouragement to Apply

Research shows that people from underrepresented groups are statistically less likely to apply for a role unless they meet every single requirement listed. If that's you — but you're genuinely excited about building Europe's in-space materials capability — we'd strongly encourage you to apply anyway. We care more about drive and capability than a perfect match on paper.

We believe diversity of background and perspective drives better engineering and better decisions, and we welcome applications regardless of gender, age, nationality, disability, religion, or sexual orientation. Severely disabled applicants will be given preference where equally qualified.
