About the Role 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.
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.
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.
Bonus Qualifications- 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.
CompensationThe US base salary range for this full-time position is between $120,000 - $300,000 annually.
