PAVE Space SA.; Villeneuve (VD); On-site; CHF 110,000 - 150,000; Full time

Job summary

PAVE Space SA. in Switzerland is seeking a propulsion systems lead to own the fluidic architecture of the spacecraft.

You will head the design of the HTP main engine feed system from concept to flight and size the cold gas RCS thruster and its feed line, ensuring robustness for orbital environments. The role requires hands-on experience with prototype assembly, testing, and a strong CAD/fluidics modelling background.

Qualifications

• 2+ years of proven experience with propellant feed systems, valves, and regulators.
• Degree in Mechanical or Aerospace Engineering, or equivalent experience.
• Strong fundamentals in fluid dynamics, thermodynamics, and heat transfer.
• Proficiency in CAD and fluidics system modelling (NX, Python, MATLAB).
• Solid understanding of the space environment and its constraints: loads, thermal, vibration, materials.
• Hands-on experience with prototype assembly, fluidic system integration, and testing.
• Fluent English (our working language).
• Nice to have: full prototype lifecycle experience, French language skills, flight-qualified fluid systems.

Responsibilities

• Own the HTP engine feed system design from concept to flight.
• Size and design the cold gas RCS thruster and feed system, from concept to flight.
• Define verification and validation strategy for propulsion fluidic systems.
• Design Fluidic Ground Support Equipment for testing, validation, and launch fueling.
