Senior Test Engineer

About the role

Join a team that designs the Electrical Ground Support Equipment (EGSE) and Test Scripts that validate our spacecraft avionics before they fly. You’ll own test solutions end-to-end—hardware, software, documentation, and testing—and see your work directly contribute to mission readiness and customer acceptance.

Responsibilities

• Design & build EGSE for spacecraft avionics: select COTS instruments, design custom test boxes/panels, and develop cabling/harnesses.
• Develop test software: author automation scripts in Python; integrate with embedded test code (VxWorks/C); build LabVIEW UIs/VIs for instrument control and telemetry.
• Integrate with flight-like units: interface with embedded single board computers (SBCs) and custom analog/digital I/O for Command & Data Handling (C&DH); support EPS/power switching use cases.
• Author formal test documentation: Document test architecture and usage, Document test reconfigurability for reuse across multiple programs, Environmental Test Plans, Acceptance Test Procedures (ATPs), and configuration-controlled schematics/BOMs.
• Execute & improve: run test campaigns (functional, environmental), troubleshoot anomalies, drive root cause/corrective actions, and mentor junior engineers.
• Collaborate cross-functionally: partner with systems, firmware, manufacturing test, and program management to meet schedule, cost, and technical goals.

Requirements

• 7+ years in aerospace/defense test engineering with hands-on ownership of EGSE hardware + software + documentation.
• Proficiency in the following coding languages: Python – test automation and data handling. C – embedded systems. LabVIEW - building production-grade instrument control and operator UIs.
• Practical experience selecting/integrating COTS instruments (PSUs, loads, DAQ, scopes) and designing custom test fixtures/cable assemblies.
• Ability to write clear ATPs/I&T plans and maintain accurate schematics/parts lists.
• Strong debugging skills across analog/digital interfaces; comfortable reading schematics and interpreting telemetry.
• U.S. person (due to export-controlled work).

Qualifications

• Familiarity with VxWorks on embedded SBCs.
• Familiarity with pytest.
• Experience with cPCI SBCs and C&DH architectures.
• Exposure to EPS backplanes (power switching, solar array/battery management).
• VHDL/FPGA interface testing.
• Cable/harness design experience and knowledge of best practices (EMI/EMC, shielding/grounding).
• Experience with Intercept Mozaix (or similar) for schematic/BOM/document control.
• Environmental test support (thermal-vac, vibe, EMI/EMC).

Skills

• Strong problem-solving and troubleshooting skills.
• Excellent communication and collaboration abilities.
• Ability to manage multiple projects simultaneously.

Benefits

• Financial Rewards: great compensation package, annual profit sharing, matching 401k and the ability to participate in Employee Stock Purchase Plan, Flexible Spending and Health Savings Accounts.
• Work/Life Balance: Flexible paid time off, holidays and parental leave program, relocation assistance.
• Health & Welfare: Comprehensive insurance coverage including medical, dental, vision, life, disability, Employee Assistance Plan (“EAP”) and other supplemental benefit coverages.
• Growth & Development: Tuition Assistance, mentorship and coaching opportunities, leadership development and other personal growth programs.
• Collaborative and Welcoming Workplace: Inclusive culture rooted in our values, enhanced by Employee Resource Groups, and team-building activities.
