[Nyx Earth] Valve Development Engineer

The Exploration Company

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run. As a talented Valve Development Engineer, you will lead the design and development of solenoid isolation valves for our storable propulsion system, from concept through qualification — owning the electromagnetic, mechanical, and sealing design that makes the valve work reliably over the mission life. ROLE OVERVIEW Valve Design & Development * Support the design of solenoid isolation valves from concept through qualification, balancing performance, mass, reliability, and manufacturability. * Define and mature valve architecture — poppet/seat design, actuation mechanism, sealing concept — to meet functional and interface requirements. * Perform mechanical sizing and trade studies (force margins, spring rates, stroke, response time) to support design decisions. Electromagnetic & Actuation Design * Design and analyze the solenoid actuator — coil, armature, magnetic circuit — to meet response time, power, and force margin requirements. * Collaborate with electrical engineers on coil drive electronics and EMI/EMC considerations. * Support trade-offs between actuation force, power consumption, and thermal dissipation. Materials, Sealing & Propellant Compatibility * Select materials and seal designs compatible with storable propellants, ensuring long-term compatibility and low permeation/leakage. * Define sealing concepts — elastomeric or metal-to-metal — balancing leak-tightness, cycle life, and contamination sensitivity. * Coordinate with materials engineering on qualification of propellant-wetted materials. Design Verification & Cross-Functional Coordination * Define and support the verification plan for valve qualification, working closely with test engineers on test setup and success criteria. * Collaborate with manufacturing engineers to ensure design manufacturability and testability. * Support anomaly investigations and root cause analysis for valve-level issues, feeding lessons learned back into the design. KEY RESPONSIBILITIES LOCATION You will perform your duties principally at the Company's premises in Bordeaux and may be required to travel from time to time to our company’s premises in Munich in the course of your duties. WHAT WE WOULD LOVE TO SEE FROM YOU * 5+ years of hands-on experience designing valves or similar electromechanical fluid components for space or aerospace applications. * Experience in solenoid/electromagnetic actuator design (magnetic circuit design, coil design) is a strong plus. * Strong understanding of sealing technology, elastomer and metal seal design, and propellant compatibility; storable propellant experience preferred. * Proficiency in CAD (CATIA, NX, or equivalent) and mechanical analysis tools. * Experience defining and supporting qualification test campaigns for valves. * Familiarity with applicable standards for valve qualification (NASA, ECSS, or equivalent).
