About the role:

We are seeking a talented Electrical Engineer to join our hardware development team. The ideal candidate combines strong theoretical foundations with hands-on expertise in digital circuit design, sensor integration, and firmware development. This role requires someone who thrives in the lab environment and can take designs from concept through production. The position also requires ability to architect and direct the work of design and manufacturing partners often outside the US.

You will design and develop digital circuits and sensor interfaces for next-generation products, working closely with cross-functional teams to define requirements and deliver robust hardware solutions. You'll be responsible for circuit design, schematic capture, PCB layout direction, and thorough verification of designs through prototype bring-up and testing. The role includes writing and debugging firmware for embedded systems, conducting detailed failure analysis, and collaborating with manufacturing partners to ensure designs transition smoothly to production.

Education & Experience:

• BS in Electrical Engineering with 5+ years of relevant experience, or MS with 3+ years.

Technical Skills:

• Demonstrated expertise in digital circuit design including microcontrollers and high-speed digital interfaces.

• Proven experience designing sensor interfaces (ADCs, signal conditioning, multi-sensor systems).

• Strong firmware development skills in C/C++ for embedded systems with experience writing clean, maintainable code.

• Ability to write test automation scripts (typically Python) for controlling test equipment using SCPI and other industry-standard protocols.

• Proficiency with standard EE tools including oscilloscopes, logic analyzers, spectrum analyzers, and power supplies.

Lab Skills:

• Excellent hands-on debugging and troubleshooting abilities.

• Experience with board bring-up, signal integrity measurements, and design validation.

• Comfortable working independently in the lab to isolate and resolve complex hardware issues.

Preferred Qualifications

• Superb EE fundamentals.

• Experience with high-speed digital design.

• Experience with interfacing MCUs to analog sensors.

• Experience working with Joint Development Manufacturers (JDMs) or contract manufacturers through the product development lifecycle, including design for manufacturability considerations and production support.

• Experience writing production-quality firmware.
