Firmware Engineer

At Rhoda AI, we're building the full-stack foundation for the next generation of humanoid robots — from high-performance, software-defined hardware to the foundational models and video world models that control it. Our robots are designed to be generalists capable of operating in complex, real-world environments and handling scenarios unseen in training. We work at the intersection of large-scale learning, robotics, and systems, with a research team that includes researchers from Stanford, Berkeley, Harvard, and beyond.

We're not building a feature; we're building a new computing platform for physical work — and with over $400M raised, we're investing aggressively in the R&D, hardware development, and manufacturing scale-up to make that a reality.

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 Ether

CAT 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 a Senior MTS reporting directly to the VP of Hardware Engineering, with a clear path to grow into a managerial role as the firmware and controls team scales.

• 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 (
