HW Sensor Engineer

As a HW Sensor Engineer, you will drive sensors for program, specification, development, and characterization for next-generation wearable products. You will partner closely with EE, mechanical, firmware, process, test, and product teams to design robust pipelines that unlock high-fidelity metrics, improve activity and gesture detection, and enhance user experiences.

This role blends deep technical execution with cross-functional influence, impacting sensor roadmap, performance outcomes, and long-term platform strategy. 

What you will do:

Sensor Design

• Drive new sensor into products and for end to end convergence.
• Translate sensing requirements into robust hardware specifications aligned with product goals.

Regional Failure Analysis:

• Lead comprehensive root cause investigations into field returns (RMA) and production yield issues, focusing specifically on sensing subsystems including PPG, accelerometers, and thermistors.

Manufacturing Process Auditing:

• Audit assembly lines, testing stations, and calibration jigs at contract manufacturing sites to mitigate sensor performance degradation and noise sources.

Technical Feedback Loop:

• Distill complex failure data into actionable insights for US-based design and firmware teams to drive hardware iterations and improve next-generation platforms.

Yield Optimization:

• Collaborate with Quality and Operations to execute corrective actions (CAPA) aimed at enhancing manufacturing yield and minimizing "No Fault Found" (NFF) occurrences.

Advanced Characterization:

• Leverage X-ray, CT scanning, SEM, and cross-sectioning to diagnose intricate electrical and mechanical failures at the PCBA and component levels.

Documentation & Communication

• Produce clear technical documentation of sensor designs, trade studies, test plans, and performance metrics.
• Present findings and recommendations to engineering leadership and cross-disciplinary stakeholders. 

We would love to consider you for this role if you have:

1. 5+ years of experience in motion sensing, inertial measurement systems, or similar sensor design and integration roles.
2. Experience with PPG, MEMS sensors, and low-power embedded sensor interfaces.
3. Strong background in sensor characterization, signal quality analysis, embedded systems, and data integrity practices.
4. Excellent analytical problem-solving and written/verbal communication skills.
5. Collaborative mindset with experience working across hardware, firmware, and analytics teams.
