Hark; San Jose (CA); On-site; USD 120,000 - 300,000; Full time

Job summary

Hark is seeking an experienced embedded engineer to develop real-time firmware for haptic and motion control systems in a hands-on role. You will write firmware in C/C++, bench-test with scopes and analyzers, and iterate with product and design teams to deliver compelling interaction experiences.

You should have 5+ years of firmware experience on microcontrollers, plus hands-on motor/actuator control skills (PID, feed-forward, FOC) and comfort with I2C/SPI/I2S buses.

Qualifications

• 5+ years writing firmware for microcontrollers in C and C++.
• Hands-on motor or actuator control experience with PID, feed-forward, FOC, observers.
