[Nyx Earth] Valve / Component Test Engineer Verified today

Role Overview

You will plan and execute the test campaigns that qualify and accept solenoid isolation valves for our storable propulsion system, from functional and leak testing through life-cycle and propellant-compatibility testing.

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, and 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: leakage exceedances, actuation failures, response time drift, and lead root cause analysis.
• Support disposition of non-conformances and coordinate corrective actions with design and manufacturing.
• 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 where storable or hypergolic propellant simulants or fluids are used.
• 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.
• Familiarity with storable or hypergolic propellant test safety practices is a strong plus.
• Experience with data acquisition systems and instrumentation: pressure, flow, and position sensors.
• Root-cause investigation experience.
• Familiarity with applicable test standards such as NASA, ECSS, or equivalent.
• Hands-on approach to problem-solving combined with collaborative mindset across multidisciplinary teams.
• Excellent organizational skills and ability to multitask.
• Capability to work autonomously while collaborating with remote teams.
• Positive and flexible attitude in a constantly evolving environment.
• Effective communication with a wide variety of audiences.
