Job Responsibilities:
● Perform hardware bring-up of new wearable sensor modules from first power-on through functional validation
● Debug system issues across sensors, power, interfaces, and firmware
● Use firmware / low-level commands (UART, I²C, SPI, shell, or vendor tools) to configure, test, and debug hardware
● Validate sensor performance, functionality, and reliability under different operating conditions
● Execute and refine test plans, validation procedures, and debug checklists
● Collaborate closely with firmware, system, and mechanical teams to resolve issues quickly
● Work with schematic, layout, and datasheet reviews to identify potential design risks
● Document findings, root causes, and recommendations clearly for cross-functional teams
● Support rapid iteration cycles typical of early-stage wearable development
● Direct technicians, engineering designers or other technical support personnel as needed.
Skills:
● Good EE fundamentals in power and analog domain.
● Solid hands-on experience in lab equipment, such as oscillating scope, differential probes.
● Ability to drive projects with high ambiguity, multiple paths, and fuzzy future to clarity.
● Experience in consumer electronics and working with vendors/contract manufactures is a plus.
● Understanding of battery, thermal, and system integration is a plus.
● Experience in developing automated tests and validation is a plus.
Education/Experience:
● Bachelor's degree in engineering required.
● Direct experience with hardware bring-up of complex systems or modules
● Strong familiarity with sensor technologies (IMUs, optical, bio-sensing, environmental, etc.)
● Comfortable using firmware or diagnostic commands for hardware control and debug
● Proficient with lab equipment: oscilloscopes, logic analyzers, DMMs, power supplies
● Experience debugging I²C, SPI, UART and related low-speed interfaces
What Success Looks Like
● Able to independently bring up new sensor hardware with minimal documentation
● Quickly isolates issues across HW/FW boundaries
● Communicates findings clearly and drives issues to closure
● Thrives in fast-paced, ambiguous development environments
● Trusted by cross-functional partners as a hands-on bring-up and debug expert
Contract term 1 year, extendable, as we will look ahead for the product roadmap for years.
The position should be local (hybrid) and expect some lab work in the Sunnyvale office.
