Senior Test Development Engineer

What You'll Do

• Own end-to-end test development: define requirements, architect solutions, build systems, and deploy them into production
• Design test strategies from first principles for devices without existing validation frameworks
• Develop error budgets and measurement approaches for precision sensing and device characterization
• Make system-level tradeoffs between accuracy, throughput, cost, and scalability
• Architect and build custom instrumentation, including PCB design, firmware, and mechanical fixtures
• Document test systems, interfaces, and operating procedures to enable reliable handoff to production, reproducibility of results, and long-term maintainability
• Integrate test systems into automated production environments, ensuring robustness and scalability
• Partner with Device, Manufacturing, and Product teams to translate ambiguous requirements into measurable specifications and challenge assumptions
• Drive improvements in test reliability, data quality, and production throughput

What You'll Need

• 5+ years of experience in circuit design, instrumentation development, or test engineering
• Demonstrated experience in full board development from initial circuit concepts through PCB layout, including defining specifications, validating functionality at the schematic level, and executing PCB layout
• Designing with Altium 365
• Deep understanding of analog and mixed-signal circuit design
• Experience implementing analog system control using microcontrollers
• Familiarity with hardware-level communication protocols
• Ability to develop microcontroller code in C
• Strong documentation skills for clear hardware handoff to system-integration teams
• Proficiency with standard electronic test equipment
• Experience developing instrumentation, including constructing and managing error budgets
• Solid hands-on lab skills, including soldering, hardware build/test, and iterative refinement
• A first-principles mindset — you question assumptions, reframe problems from the ground up, and approach challenges with a foundational understanding rather than relying solely on precedent
• Bachelor's degree in Electrical Engineering or Physics. A PhD in a hard science or engineering discipline is strongly preferred
• Experience developing test plans from ambiguous requirements, including defining specifications, measurement approaches, error sources, and success criteria
• Demonstrated ability to reason about and make engineering tradeoffs (e.g., accuracy vs speed, noise vs architecture, modularity vs robustness)

Bonus Points For

• High current (500A+) or high voltage (1kV+) systems experience
• Experience developing with the STM32 microcontroller platform
• Experience with reliability or environmental test systems

Compensation: Salary Range $170,000—$220,000 USD (also includes equity and benefits)
