[Nyx Earth] Valve / Component Test Engineer Verified today

About Nyx

The Exploration Company is developing Nyx, a modular and reusable space orbital vehicle designed to be refuelled in orbit and carry cargo, and potentially humans in future.

Your Role

As Valve / Component Test Engineer, you will plan and execute test campaigns that qualify and accept solenoid isolation valves for our storable propulsion system.

Test Planning and Procedure Development

• Develop test plans and procedures for solenoid isolation valve qualification, acceptance, and life testing (functional response, leak, proof/burst, cycle life, propellant compatibility).
• Define test success criteria and correlate them with valve functional and performance requirements.
• Support verification and validation planning in coordination with system functional and design engineers.

Test Execution and Data Acquisition

• Execute functional, performance, and environmental test campaigns on solenoid valves (cold flow, vacuum, thermal, vibration, EMI where applicable).
• Set up and operate test benches, instrumentation, and data acquisition systems for valve response time, leak rate, and flow characterization.
• Reduce and analyze test data, comparing results against predictions and requirements.

Anomaly Investigation and Root Cause Analysis

• Investigate test anomalies such as leakage exceedances, actuation failures, and response time drift.
• Lead root cause analysis and support disposition of non-conformances.
• Coordinate corrective actions with design and manufacturing teams.
• Document test results and anomalies for certification and configuration traceability.

Test Facility, Tooling and Safety

• Design and maintain test fixtures, ground support equipment, and facility setups for valve testing, including propellant-compatible test benches.
• Ensure safe handling procedures for test operations, particularly with storable and hypergolic propellant simulants or fluids.
• Continuously improve test infrastructure, automation, and data processing tools.

What We're Looking For

• B.S. in mechanical or aerospace engineering with 3+ years of hands-on test engineering experience with valves or fluid components.
• Experience with functional, leak, and life-cycle testing of solenoid or similar valves.
• Experience with data acquisition systems and instrumentation (pressure, flow, position sensors).
• Root-cause investigation experience.
• Familiarity with applicable test standards (NASA, ECSS, or equivalent).
• Familiarity with storable/hypergolic propellant test safety practices is a strong plus.

Skills and Behaviours

• Hands-on approach to problem-solving with collaborative mindset across multidisciplinary teams.
• Excellent organizational skills and ability to multitask.
• Capable of working autonomously whilst collaborating with remote teams.
• Positive and flexible attitude in a constantly evolving environment.
• Ability to communicate effectively with a wide variety of audiences.
