Job description

As we continue developing our 45 kN rocket engine, we are looking for an Engine Fluidics Engineer to take ownership of the design and optimisation of the propellant feed system. You will play a central role in ensuring the reliable delivery of fluids throughout the propulsion system, from tanks to the combustion chamber.

This is a chance to work on core rocket technology in a fast-moving startup and directly influence the performance of our engine.

You will own

What we are looking for

Professional experience (2 years+) with propellant feed systems, valves, regulators, bellows, preferably for aeronautical, space, or automotive application.

Strong understanding of fluid dynamics, thermodynamics, and heat transfer.

Proficiency in CAD and system modelling/simulation (Python, MATLAB, Modelica, or equivalent).

Practical experience with test benches and instrumentation (a plus).

Clear and effective English communication skills.

If you’re ready to apply your expertise in fluid systems and rocket propulsion to build the next generation of spacecraft engines, join us at PAVE Space.

We are a fully on-site company, and all roles require daily in-person work at our office in Villeneuve (VD)

You will fit if

Passionate about rocket propulsion and fluid systems.

Analytical and detail-driven, with a strong ability to model and simulate complex flow behaviour.

Hands-on, eager to design, test, and validate fluid systems in real hardware.

Comfortable with taking ownership of system design and delivering results under tight schedules.

Adaptable and proactive, thriving in a fast-paced startup environment.

Committed to precision, reliability, and safety in fluid handling.

A rare opportunity to work on the design and development of rocket propulsion systems in Switzerland.

A dynamic startup environment where your contributions are immediately impactful.

Hands-on involvement in the design, analysis, and testing of fluid systems.

Collaboration with experts in propulsion, GNC, mission design, and spacecraft systems.

Strong growth opportunities, both technical and leadership, in one of aerospace’s most exciting domains.
