Job summary

GATE Space in Vienna, Austria seeks a Mechanical Design Engineer to drive end-to-end propulsion design, from concept to flight-ready hardware, with a strong focus on 3D CAD modeling and manufacturing drawings.

You will apply DTC/DFM principles, perform FEA/CFD analyses, and build Python models to support design decisions. This in-person role offers travel to Europe/US, competitive salary, and a collaborative, international team.

Qualifications

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related field.
• Proven industry experience (at least 4 years) taking complex hardware from early conceptual design through multiple iteration cycles to a mature, tested product.
• Exceptional proficiency in CAD design (Siemens NX preferred) with a strong portfolio of designed and manufactured components.
• Expertise in mechanical analysis with FEA tools.
• Direct experience designing and developing pressurized fluid systems, valves, and full combustion devices.
• Solid foundational knowledge of thermodynamics, fluid mechanics, combustion, and heat transfer.
• Proficiency in Python or similar tools for numerical analysis and data processing.
• Demonstrated hands-on experience from assembly and testing of structural, propulsion or robotic systems.
• Exceptional communication skills with the ability to distill complex technical trade-offs for cross-functional teams.
• Ability to thrive in a fast-paced, dynamic environment, seamlessly adapting to evolving priorities and timelines.
• Optional but desired hands-on experience with nitrous-oxide-based propulsion systems.
• Optional but desired experience in fluid analysis with CFD and numeric tools.
• Optional but desired development of flight hardware for spacecrafts, propulsion systems and/or thrusters.
• Optional but desired track record of developing and delivering safety critical hardware (aerospace, medical, railway systems).

Responsibilities

• Design and optimize complex 3D models and manufacturing drawings.
• Lead end-to-end design ownership of propulsion systems from concept to flight-ready hardware.
• Define component specifications and execute trade-off studies for pressurized and fluid systems.
• Drive design maturation with FEA and CFD.
• Build system-level numerical models in Python and perform sizing trades.
• Collaborate with cross-functional teams under Design for Manufacturing (DFM) and testing feedback.
