We are looking for a Composite Development Engineer to build the material foundation of our rocket structures and generate material data that design and analysis can trust.You will work across material selection, process development, specimen preparation, laboratory testing, and component validation. Your work will ensure that material properties are measured on the materials we use, made with the processes we intend to employ, and suitable for real engineering decisions.About usWe’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 responsibilitiesDefine material requirements based on system, component, manufacturing, and structural interfaces.Select composite material systems and qualify suitable manufacturing processes.Plan and run coupon-level characterisation campaigns, from specimen preparation and testing through to usable design values.Develop and characterise new material systems and processing methods.Validate material properties on manufactured components and feed results bac
