Embedded Software Engineer, Haptics

Hark•San Jose, CA

1h•$120,000 - $300,000

About The Position

Hark is looking for an experience-focused, hands-on embedded engineer to build haptic and motion control system firmware and software that deliver incredible interaction experiences. We care a lot about how things feel, and how the people that use them feel, and we want someone who shares that craft mindset.

Requirements

5+ years writing firmware for microcontrollers in C and C++.
Demonstrated hands-on motor or actuator control work that shipped — PID, feed-forward, FOC, observers, and similar techniques.
Comfort on the bench with scopes, logic analyzers, and bus traffic over I²C, SPI, or I²S.
Working knowledge of Python or another scripting language for measurement automation and quick data analysis.
Clear written communication — you can explain a tradeoff to a non-firmware teammate without losing them.
A strong instinct for what distinguishes haptics that feel right.

Nice To Haves

DSP fundamentals: filtering, time-domain shaping, and basic perceptual modeling.
RTOS experience or comfort with bare-metal scheduling for hard real-time control loops.
Familiarity with low-power system design and the measurement habits that come with it.
Prior work on consumer haptics, audio, or other systems where feel and timing are visible to the user.

Responsibilities

Write real-time firmware in C and C++ that drives motion and haptic systems.
Close the loop on response time and feel. characterize actuator behavior on the bench and tune controllers until the result is genuinely pleasant to use.
Stand up early hardware, prove out feel and timing in prototype form, and shape the final shipping experience alongside product and industrial design partners.
