Nice to Have + Experience with RF test and characterization (VNAs, VSAs, signal chains, antenna range testing) + Familiarity with space hardware test standards (GEVS, SMC-S-016, MIL-STD-1540, DO-160) + Experience with mixed-signal test system (Power + High-speed digital + RF) test infrastructure. + Experience with Medium Voltage systems, high energy storage systems, and low-voltage/high-current interfaces. + Experience with PLC programming (TwinCAT, Allen-Bradley, or similar) + Knowledge of digital/analog interfaces: CAN bus, SPI, I2C, RS-422, UART, TCP/IP + Experience with LabVIEW, MATLAB, or custom DAQ solutions + Familiarity with requirements management tools (Jama, DOORS) and documentation platforms (Jira, Confluence) + Experience supporting transition from development test to production-scale acceptance testing + Background in TVAC, vibration, or other environmental qualification campaigns ## Description We are looking for a Hardware Test Engineer to design, build, and automate test systems that verify and validate our flight hardware. This role spans the full test lifecycle - from early development benchtop setups through qualification campaigns and production - and sits at the intersection of electrical, mechanical, RF, and software engineering. You will own test infrastructure end-to-end: defining requirements, designing ground support and test equipment (EGSE/MGSE), writing and executing test procedures, and driving automation to scale with our hardware cadence. This is a hands-on role. You will be in the lab regularly, and your work will directly determine what goes to flight. Responsibilities * Test System Design & Development + Architect, design, and build test racks, bench-top platforms, and automated test equipment to support hardware development, qualification, and production + Design and produce test assets including electrical panels, harnessing, fixtures, PCBAs, and ground support equipment + Select COTS instrumentation and/or design custom hardware to apply flight-like loads, measure signals, and power units under test + Create and maintain electrical schematics, harnessing diagrams, and integration documentation + Lead test architecture decisions, drive standards, and own technical roadmap for test infrastructure Test Execution & Verification + Write, review, and execute test procedures and verification plans across development, qualification, and acceptance test campaigns + Support environmental testing including thermal/vacuum (TVAC), vibration, and HALT/HASS + Troubleshoot hardware anomalies, lead root cause investigations, and develop corrective action plans Automation & Software + Develop Python-based test scripts to automate data collection, instrument control (SCPI/VISA), and test reporting + Integrate test systems with telemetry pipelines and production documentation tools + Design intuitive operator interfaces that make complex test equipment accessible and auditable
