Fluidic Systems Engineer (Leganés)

IENAI SPACE is an early-stage startup located in Madrid, developing an end-to-end ecosystem of in-space mobility products, including propulsion systems and engineering SaaS. We are a highly innovative company in the “New Space” sector; the team is made up of a dynamic and multidisciplinary group of engineers, PhDs and developers, looking to revolutionize space mobility for the adoption of propulsion products in the smallest of satellites. We recently kickstarted our commercial phase with our first product: 360™, a Mission and Space Mobility analysis SaaS.

Our mission is to build tailored, end-to-end space mobility products and services for the next generation of small satellites empowering a sustainable new space economy. We believe this is possible because we rely on our values: Infinite Innovation, Extraterrestrial Excellence, Cosmic Collaboration, Astronomical Agility and Planetary Passion.

How will you contribute to IENAI SPACE?

As Fluid Systems Engineer you will own the development of the Propellant Management Unit (PMU) of ATHENA, the subsystem responsible for storing, conditioning and delivering ionic liquid propellant to the thruster.

This is not a conventional propulsion role. The PMU operates at low pressures, delivers flow rates in the μL/s range and handles an ionic liquid propellant that is conductive, hygroscopic, and sensitive to dissolved or trapped gas. The design envelope is far closer to precision vacuum fluidics or analytical instrumentation than to the propellant management systems of hall thrusters or chemical propulsion.

The current PMU design is functional and flight-heritage is accumulating, but the design requires continued engineering development toward production readiness. In parallel, you will lead the development of our in-vacuum filling setup, bringing a working prototype to a repeatable, documented process.

Your key responsibilities will include:
- Continued mechanical and functional development of the ATHENA PMU, including rel Postúlate en Kit Empleo: kitempleo.es/empleo/6trrqg
