About the role
About the Company
Rhoda AI is building the next generation of generalist intelligent robots. We own the full robotics stack from high-performance hardware and robot systems to the infrastructure and state-of-the-art foundation world models that control our robots.
Responsibilities
- Select and tune RTOS, define priorities, and optimize interrupt and DMA paths
- Design, implement, and maintain low-level firmware for real-time motion control nodes over EtherCAT
- Develop synchronization and communication layers ensuring deterministic cycle times
- Configure and optimize EtherCAT masters and slaves
- Implement real-time safety mechanisms such as Safe Torque Off and watchdogs
- Collaborate with Electronics, Controls, and Systems teams to define timing budgets
- Contribute to the architecture of the hardware abstraction layer (HAL) and firmware APIs
- Develop unit, HIL, and integration tests for firmware validation
- Profile and optimize ISR and DMA paths to minimize latency and jitter
- Support bring-up and debugging of custom actuator controllers and sensor boards
- Document firmware architecture and safety compliance evidence
Requirements
- Bachelor's or higher in Electrical Engineering, Computer Engineering, or Robotics
- 2+ years of experience in embedded firmware development for real-time control systems
- Experience with low-level system interfaces (I2C, SPI, Ethernet, USB, CAN bus)
- Experience with micro-controller firmware development across ARM Cortex-M architectures
- Proficiency in C/C++ and experience with low-level debugging (JTAG, logic analyzers, oscilloscopes)
- Experience with RTOS (FreeRTOS, Zephyr RTOS)
- Familiarity with SPI, I²C, UART, PWM, ADC, and sensor interface design
- Ability to write reliable code in safety-critical environments
- Evidence of shipping real-time-critical products
Preferred Qualifications
- Embedded Linux software development and BSP development
- Linux kernel programming including device tree and kernel modules
- Experience with GMSL2 and MIPI-CSI2 camera drivers
- Experience with Field-Oriented Control (FOC) for BLDC motor drives
- Yocto Project / Bitbake experience
