Senior Test Engineer for Space EGSE and Embedded Systems

Space EGSE Senior Test Engineer / Embedded Systems

Phoenix / Gilbert, AZ

$130–158K + Relocation | 9/80 Schedule (Every Other Friday Off)

We’re seeking a hands-on Senior Test Engineer to design and build Electrical Ground Support Equipment (EGSE) used to validate space- and defense-grade avionics and power electronics. This role sits at the intersection of test hardware, embedded software, and real-time systems and is ideal for engineers who like working close to the hardware.

What You’ll Do

• Architect and develop EGSE test systems from requirements through qualification, including:
• 
  
• COTS instrumentation (PXI, DAQ, power supplies, signal generators)
• Custom test enclosures and cabling
• 
  
• Develop embedded test software in C interacting directly with SBCs running VxWorks (RTOS)
• Create LabVIEW VIs for instrument control, telemetry monitoring, and operator UIs
• Build automated test frameworks using Python or PERL to coordinate LabVIEW and VxWorks execution
• Support testing of:

• 
  
• Command & Data Handling (C&DH) boards
• Analog and digital I/O
• Electrical Power System (EPS) boards (power switching, battery charging, solar array interfaces)
• FPGA-based subsystems (integration/debug level)
• 
  
• Debug issues across hardware, firmware, and software boundaries using lab tools (JTAG, scopes, logic analyzers)
• Author test plans, procedures, schematics, and qualification documentation
• Collaborate closely with systems, firmware, FPGA, and hardware design teams
• Mentor junior engineers on test system design and embedded best practices

Required Background

• BSEE (or similar) with 7+ years in EGSE, embedded systems, or hardware-centric test engineering

• Strong embedded C experience on real hardware (SBCs, microcontrollers, avionics platforms)
• Hands-on LabVIEW experience for automated test systems and instrument control
• Experience working with or around VxWorks or another RTOS (VxWorks strongly preferred)
• Familiarity with Python or PERL for test automation and orchestration
• Comfortable working with analog/digital electronics, power systems, and hardware interfaces
• Experience creating cable drawings, schematics, and test documentation
• Self-directed engineer who can own test systems end-to-end
• Ability to work on U.S. export-controlled programs

Nice-to-Have (Differentiators)

• Spaceflight, avionics, or defense electronics experience
• cPCI / VPX / embedded SBC platforms
• FPGA familiarity (VHDL exposure a plus)
• Qualification, acceptance, or environmental testing experience
• Prior ownership of test stations from concept through deployment

Why You’ll Like It Here

• Work on mission-critical space and defense hardware
• Deep technical ownership — not a “button-pushing” test role
• Stable programs with long-term impact
• Competitive compensation, bonus, 401(k) match, ESPP
• Relocation assistance and strong benefits package
