Job description

We are looking for a Graduate / Junior StructuresEngineer to begin your career in rocket structures and grow quickly through hands‑on responsibility. You will have the opportunity to develop across design, analysis, manufacturing, materials, and testing while working closely with experienced structural engineers.

This role is designed for someone curious, practical, and eager to contribute wherever the team needs support. You will work with real hardware from day one and take on increasing ownership as your strengths and experience develop.

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 suborbital and 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 engineering of rocket structures, from geometry and modelling through to calculation and evaluation using CAD and FEA.

• Gain hands‑on experience manufacturing and prototyping composite hardware using filament‑winding machines and curing equipment.

• Help prepare and conduct structural tests and material‑characterisation activities, including tensile testing, DSC, and microscopy.

• Process engineering data and automate repetitive tasks using Python where useful.

• Document methods, results, and technical decisions clearly.

• Work closely with senior engineers and take on increasing ownership as your skills develop.

What we are looking for

• A Bachelor’s or Master’s degree in aerospace, mechanical, structural, or materials engineering, or a Master’s degree currently in progress.

• A solid foundation in structural mechanics, materials science, or manufacturing processes.

• Hands‑on experience from a student engineering team, particularly in rocketry, Formula Student, aerospace, or a similar practical environment.

• Genuine curiosity and a practical, quality‑conscious mindset.

• Fluent English.

• The ability to learn quickly, work collaboratively, and contribute across design, analysis, manufacturing, and testing.

Desirable experience

• Composite materials, filament winding, curing, or structural testing.

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

• Basic Python scripting for data processing or task automation.

• 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.
