Senior Electronics Design Engineer

About Us
Symbiokinetics builds robotic systems that learn skilled physical interaction from human experts. Our robots operate in direct contact with people in high-stakes environments. They need to feel intuitive, predictable, and completely safe.

About the Role
You will design and implement the electronics, firmware, and signal conditioning that connect our sensors and actuators to the rest of our stack. You'll work closely with our VP of Engineering on board bring-up, motor control, and sensor integration, while owning subsystems end-to-end.
This is a hands-on role. You'll spend time at a bench with an oscilloscope as often as at a keyboard.

What You'll Do
Implement drivers, firmware, and register-level configuration for sensors and actuators
Design and debug signal conditioning circuits
Bring up new sensor and motor control boards (SPI, I2C, UART, CAN, EtherCAT)
Support motor control development: current sensing, commutation, torque loop integration
Build and maintain data acquisition rigs for recording sensor data during robot operation
Read datasheets, write firmware for microcontrollers, debug communication protocols
Collaborate with mechanical team on electronics packaging and thermal/power constraints

Required
BS or MS in Electrical Engineering, Mechatronics, or related field
8-10 years working with embedded systems on physical products
Experience with schematics capture and circuit board layout
Proficient in C/C++
Experience with microcontrollers (STM32, ESP32, or similar) is a big plus
Experience with sensor interfacing: ADCs, signal conditioning, filtering, calibration
Comfortable reading schematics and datasheets, debugging with oscilloscope and logic analyzer
Comfortable with at least one PCB design software (KiCad, Altium, or equivalent)
Experience with communication protocols (SPI, I2C, CAN)
Able to solder, rework boards, and build test fixtures

Nice to Have
Motor control experience (BLDC commutation, FOC, current/torque loops)
Experience with force/torque sensors, load cells, or strain gauge bridges
Signal processing: digital filtering, noise characterization, oversampling
FPGA experience (for low-latency signal processing)
Familiarity with ROS2 for hardware interfacing
Experience miniaturizing electronics for constrained form factor
Power electronics

Benefits
Comprehensive health, vision, and dental insurance
401(k)
Office lunches
