Mechanical engineering / Composite Structures internship

Mechanical Engineering / Composite Structures Intern

We are looking for a Mechanical Engineering / Composite Structures Intern to support the design, manufacture, testing, and improvement of the composite structures used in our launch vehicles.

This is a hands-on opportunity to work closely with structural engineers, composite manufacturing engineers, technicians, and the workshop team. You will contribute to real hardware while developing practical experience across CAD, composite materials, manufacturing processes, structural testing, and engineering analysis.

About us

We’re a Germany-based rocketry startup currently in stealth mode, scaling up rapidly to meet the demand for high-performance, reliable, and scalable solid propulsion technologies for space and defense applications.

We are already launching ballistic rockets on a regular basis, have just crossed €10m in revenue for our first operating year and are applying our knowledge toward the development of an orbital rocket.

We are working hard to build something truly spectacular.

To thrive here you will need to be comfortable working at pace, with the autonomy to make decisions and execute on them quickly. If you’re excited by hard technical challenges and want a role where you will make a real difference each day to the future of the company, we may be the place for you.

At our company, job titles and career progression are earned, not determined by years of experience alone. They reflect the responsibility you take on and the dedication you bring to each project. If you’re ready to rise to the challenge, we’d love to hear from you.

Key responsibilities

• Support the design and modelling of primary and secondary composite structures, components, joints, and interfaces.

• Assist with CAD, basic structural calculations, FEA, design documentation, and preparation of technical drawings.

• Support composite manufacturing activities including lay-up, filament winding, vacuum bagging, curing, and demoulding.

• Help design and produce tooling, mandrels, fixtures, prototypes, and test articles.

• Prepare and support structural tests, material characterisation, inspections, and data collection.

• Document work clearly and contribute to process improvements across design, manufacturing, and testing.

What we are looking for

• Currently studying mechanical engineering, aerospace engineering, materials science, composite engineering, or a related subject.

• A solid foundation in mechanics, materials, structures, manufacturing processes, or engineering design.

• Practical experience through a student engineering team, particularly in rocketry, Formula Student, robotics, aerospace, or a similar project.

• Familiarity with CAD and an interest in developing skills in composite structures and manufacturing.

• A practical, curious, and quality-conscious mindset, with a willingness to work hands-on with hardware.

• Fluent English and the ability to communicate technical work clearly.

Desirable experience

• Composite materials, carbon fibre, resin systems, prepreg, wet lay-up, or filament winding.

• CAD or FEA work through academic, personal, or extracurricular projects.

• Tooling, mandrel, fixture, prototype, or workshop experience.

• Structural testing, materials testing, microscopy, or laboratory work.

• Python, MATLAB, or similar tools for engineering calculations and data analysis.

• Working proficiency in German.

Benefits and important information:

• We offer top-decile compensation packages, bonuses and meaningful equity, to attract exceptional aerospace talent.

• Every employee is awarded stock options in the company, you will directly benefit from your own hard work and success.

• Comprehensive relocation support including flights, shipping and visas.

• Lunch, dinner and drinks provided everyday

• Free access to shared company housing

Please note, we are a fast paced, hyper-scaling startup. You will need to be comfortable working extended hours with high levels of autonomy, ownership, and flexibility, with contracts structured around a 48-hour working week.

We are committed to building an equitable and inclusive workplace where everyone feels valued, has equal access to opportunity, and can thrive. We welcome different perspectives, backgrounds, and experiences—and believe our differences make us stronger.
