Rocket Engine Structural Engineer (m/f/d)

Rocket Engine Structural Engineer (m/f/d)

POLARIS Raumflugzeuge GmbH develops innovative transportation systems that redefine access to space for payloads and passengers. With now 70 dedicated colleagues, we are working at two locations to make our vision reality. We are continuing to expand our team and are looking to fill the position of a Rocket Engine Structural Engineer (m/f/d).

Your mission

• Perform structural design and analysis of rocket engines at system, subsystem, and component level
• Conduct strength, stiffness, stability, and life analyses under static, dynamic, pressure, and thermal loads
• Define and assess structural load cases from operation, launch, testing, and off-nominal scenarios
• Support mechanical design of load-bearing components such as combustion chambers, nozzles, housings, mounts, and interfaces
• Perform and own finite element analyses (linear/nonlinear, thermo-mechanical, and fatigue where applicable)
• Define boundary conditions, safety factors, and structural margins
• Correlate analysis results with test data and derive design improvements
• Support structural, pressure, and load testing activities, including test evaluation
• Collaborate closely with interdisciplinary teams
• Document assumptions, models, results, and structural design decisions

Your profile

• Degree in Space Engineering, Aerospace Engineering (M.Sc.) or similar
• Minimum of 2 years of full-time experience
• Strong background in structural mechanics, strength of materials, and material behavior
• Experience in structural design and analysis of complex engineering systems
• Strong background in ANSYS Mechanical
• Experience with high-temperature, pressure-loaded, and dynamically loaded structures
• Understanding of thermo-mechanical coupling and material behavior under extreme conditions
• Ability to interpret and validate simulation results using test data
• Proactive thinking, high level of motivation, flexibility, and team-working skills

Join us in shaping the future of space transportation and making a positive impact. If your profile fits our requirements, apply now by sending your complete application portfolio, including CV, certificates and a cover letter outlining your relevant experience and why you are the ideal candidate for this role.

About Us

The German aerospace start-up POLARIS Raumflugzeuge GmbH is developing a revolutionary reusable space launch and hypersonic transport system that operates like an aircraft.

Based on more than 30 years of German and European spaceplane research, the development of the spaceplane AURORA began at the German Aerospace Center DLR. Aurora combines aircraft and rocket launcher technologies with a unique vehicle design, and offers a game-changing economic viability as well as opening the door for routine low-cost and safe access to space.

In order to validate the technology and accelerate the spaceplane development, POLARIS has been developing a series of scaled flight demonstrators.
