Darwin Space are currently hiring for a Fluidics Systems Engineer on behalf of a business in Madrid.
Responsibilities
* Continued mechanical and functional development of the ATHENA PMU, including reliability improvements and production-readiness work.
* Developing and qualifying the in-vacuum propellant filling setup, including outgassing protocols, contamination control and fill calibration procedures.
* Characterising PMU performance: flow delivery, pressure stability, gas management and fill accuracy.
* Writing and maintaining test procedures, assembly instructions and qualification documentation.
* Working closely with the thruster and power electronics teams during integrated testing and firing campaigns.
* Contributing to make-vs-buy decisions and supplier interactions for PMU components.
Qualifications & Skills
* Background in vacuum systems engineering, precision fluidics, analytical instrumentation, or a closely related field, demonstrated either through industry experience or research.
* Hands-on experience handling sensitive or reactive liquids (hygroscopic, conductive, or corrosive media) in a laboratory or production context.
* Familiarity with vacuum hardware: pumping systems, pressure measurement at low ranges, outgassing characterisation, leak detection.
* Experience designing or assembling precision sealed systems (seals, fittings, polymer-to-metal interfaces).
* Rigorous experimental habits: clear documentation, awareness of contamination sources, systematic troubleshooting.
* Comfortable working in a small team where the scope of your role will evolve.
* Proficiency in mechanical CAD (Fusion 360, SolidWorks, or equivalent).
* Direct experience with ionic liquids or electrochemical systems.
* Familiarity with space environmental requirements (thermal vacuum, ECSS or NASA outgassing standards).
* Experience with low-pressure pneumatic proof testing and pressure system compliance.
* Background in microfluidics, MEMS, or lab-on-chip systems.
