At Rhoda AI, we’re 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. Our robots are designed to be generalists capable of operating in complex, real-world environments and handling long-tail edge cases, made possible by our cutting edge research and end-to-end system design. We’ve raised over $450M and are investing aggressively in model research, infrastructure, hardware development, and manufacturing scale-up to make generalist robotics a reality.
About the role
You will own the development of Rhoda’s low-level firmware stack for distributed real-time control across humanoid platforms. This role centers on deterministic communication, control-loop synchronization, and embedded software robustness in an EtherCAT environment spanning dozens of joints, sensors, and distributed controllers. You will design, implement, and validate firmware components that guarantee sub-millisecond coordination between motor drivers, safety controllers, and perception nodes — bridging the mechanical, electrical, and control domains.
This role is an MTS with a clear path to grow!
What You’ll Do
•
Select and tune RTOS; define priorities and scheduling; optimize interrupt and DMA paths; harden watchdogs and recovery; measure and guard timing budgets
•
Design, implement, and maintain low-level firmware for real-time motion control nodes over EtherCAT
•
Develop synchronization and communication layers ensuring deterministic cycle times (<1ms)
•
Configure and optimize EtherCAT masters and slaves (distributed clocks, mailbox protocols, PDO mapping)
