About the role

Muon Space is seeking an experienced Senior Electrical Test Engineer to join our team in San Jose, CA. In this role, you will own the architecture, development, and scaling of the test infrastructure that ensures zero hardware failures at launch. You will drive the test strategy for satellite avionics, design test racks and custom PCBs or fixtures as required. This is the first electrical test role, so you will help define the standards and set the bar for electrical test infrastructure. You will collaborate with the test and reliability organisation and be part of the electrical engineering team so test development starts with PCBA development.

This position is onsite, requiring work in the San Jose, CA office five days per week.

Responsibilities

  • Work with test and reliability to define hardware and software for automated test racks for avionics modules (primarily PCBAs)
  • Define the overarching validation strategy and test plans/methodologies for spacecraft avionics including flight computers, power systems, and RF/communication payloads
  • Partner with hardware design engineers early in the product lifecycle to implement Design for Test (DFT) and Design for Manufacturability (DFM) requirements
  • Write and maintain Python scripts based on the software test framework used throughout the hardware organisation
  • Create methods for rack self-test and preventative maintenance so racks can be monitored and maintained by the production team
  • Guide and mentor junior test and hardware engineers, establish engineering best practices for the test team, and lead technical design reviews for test infrastructure
  • Create custom electrical or mechanical fixturing when required to make tests fast and easy to run

Qualifications

  • 3+ years of experience in hardware test engineering; 8+ years of total relevant software/hardware engineering experience
  • Strong knowledge of electronic components, circuits, and test equipment (oscilloscopes, multimeters, power supplies)
  • Familiarity with schematic capture and PCB layout software (Altium, Cadence/Orcad)
  • Understanding of microcontrollers and common communication interfaces (UART, SPI, I2C, CAN, Ethernet)
  • Experience with embedded systems, embedded programming concepts, and comfortable in a Linux development environment
  • Strong knowledge of scripting/Python and use of AI to expedite script development
  • Knowledge of Git or other change control systems
  • Strong problem-solving skills and hands-on approach to engineering challenges
  • Excellent communication and teamwork skills
  • Desire to learn and contribute in a fast-paced, dynamic environment
  • B.S. or M.S. in Electrical Engineering, Computer Engineering, or related field (preferred but not required)

Nice-to-have skills

  • Experience with electronics for space applications
  • Experience with FPGAs, SoC, or embedded Linux platforms
  • Knowledge of high-speed digital interfaces like PCIe, DRAM, CSI, 25G Ethernet
  • Experience with RF test equipment and test methodologies (spectrum analysers, VNAs, power metres, frequency generators)
  • Familiarity with aerospace test and quality standards such as SMC-S-016
  • Previous startup experience or experience working in a fast-paced environment

Compensation

Salary range: $184,000 - $208,000, plus competitive equity grant and comprehensive benefits package. Final compensation determined based on skills, qualifications, experience, and geographic location.
