Senior/Principal Electrical Test Engineer

The role

You will own the hardware test systems for subsea electronics, including racks, fixtures, harnesses, and automation software. You will partner with design engineers to validate systems across various environmental conditions like extreme pressure and temperature.

What you will do

• Own hardware test systems end to end including requirements, architecture, design, build, and documentation
• Derive test requirements from subsystem design and interface documents
• Design and build test racks, unit-under-test fixtures, and interface harnesses
• Write automated test software for instrument control and data acquisition
• Plan and run development, qualification, and acceptance test campaigns
• Write test plans, procedures, and reports and set pass/fail criteria
• Troubleshoot failures to the component level and drive root cause and corrective action
• Build scalable test capability from development units to production acceptance
• Help define test standards, lab infrastructure, and supplier base

Required qualifications

• Bachelor's degree in electrical engineering or a related STEM discipline
• 3+ years of experience in hardware or electronics test engineering, instrumentation, or data acquisition system design for complex hardware
• Hands-on experience designing, building, and bringing up electronics test systems
• Fluency with electrical lab equipment including oscilloscopes, DMMs, programmable power supplies, electronic loads, and source measure units
• Working knowledge of common hardware interfaces: CAN, RS-422/485, Ethernet, SPI, I2C, and analog signal conditioning and conversion
• Ability to read schematics and debug electronics at the board and component level
• Experience writing test plans, procedures, and reports, and defining pass/fail criteria with design engineers
• Strong communication skills
• Ability to work in a fast-paced, prototype-driven environment
• Ability to work onsite in Seattle and travel to deployment sites as required
• Experience writing software for test automation

Nice to have

• Experience testing hardware for subsea, marine, aerospace, or defense systems
• Experience with environmental qualification testing: pressure/hyperbaric, thermal, vibration, and shock
• Experience with high-voltage and high-power electronics test, including safety interlocks, hipot, and insulation resistance
• Experience with hardware-in-the-loop (HIL) test and simulation of subsystem interfaces
• Experience with PLCs or industrial control hardware for test-cell automation and safety
• Understanding of metrology, measurement uncertainty, and calibration practice
• Proficiency writing software in Rust or Python

Benefits

• Health, Dental, and Vision insurance coverage
• Flexible PTO including 12 paid company holidays
• Travel to deployment sites in locations like the Pacific Northwest, Hawaii, Iceland, Japan, New Zealand, and the Azores
• Participate in sea trials and deployment operations
• Company-sponsored recreational dive certification
• Access to the company boat
• Free meals and snacks
