Firmware Engineer — Dexterous Hand Systems (human)

Your mission & challenges

The Humanoid Hand packs dozens of actuated finger and palm drive stages into a form factor that must be safe, precise, and responsive at human-scale speeds. As Firmware Engineer for Dexterous Hand Systems, your mission is to build and own the embedded firmware stack that makes this possible — from the motor control loops running on Infineon TLE9879 drivers, through the RTOS HAL layer and Qualcomm IQ-series bring-up, to the communication stack that connects the hand to the rest of the robot in real time.

This is a deeply technical, hands-on role. You will work in close collaboration with the Electronics and Control engineer to close the firmware–controls loop on real hardware, define and implement communication protocols that meet deterministic timing requirements, and architect safety monitoring targeting ASIL-B compliance. The hand is a new product — many of the hardest problems do not have established answers yet, and your engineering judgment will directly shape the architecture.

Develop and maintain field-oriented control (FOC) firmware for BLDC actuators across all finger and palm drive stages — tuning and debugging on real hardware, not library integration

Architect and own the hardware abstraction layer (HAL) on RTOS (e.g. Zephyr) and Linux Kernel targets, including full Qualcomm IQ-series SOM bring-up

Define and implement the full communication stack: FastDDS and Micro-XRCE-DDS for ROS 2 integration, TSN (IEEE 802.1AS/Qbv) for deterministic Ethernet, CAN, SPI, and I²C for local device buses

Implement multi-level watchdog and safety monitoring architecture targeting ASIL-B compliance

Collaborate with the Electronics team on hardware bring-up and motor driver integration (Infineon TLE9879); collaborate with the Control engineer to ensure the firmware layer meets the timing and observability requirements of the torque and impedance control loops running above it

What we can look forward to

Embedded firmware and real-time systems

5+ years of embedded firmware development in real-time systems — RTOS experience is mandatory; Zephyr RTOS experience is strongly preferred

Deep FOC implementation experience: you have tuned and debugged field-oriented control on real BLDC actuators, not just configured a library; you understand current loop bandwidth, back-EMF compensation, and commutation timing at the implementation level

Linux Kernel driver development: device tree authoring, custom driver implementation, and low-level peripheral bring-up (SPI, I²C, CAN)

Hands-on DDS middleware experience in embedded or edge contexts: FastDDS, Micro-XRCE-DDS, or equivalent in a resource-constrained environment

Communication and safety

Practical experience implementing deterministic communication stacks: TSN (IEEE 802.1AS/Qbv), CAN bus protocol stack, or equivalent in a latency-critical embedded system

Functional safety experience (ISO 13849 or IEC 61508) — particularly watchdog architectures and safe-state design for actuated systems; ASIL-B or SIL 2 level experience is a strong plus

Nice to have

Qualcomm IQ platform (or similar) BSP and bring-up experience

Infineon TLE9879 or similar integrated motor driver bring-up and configuration

Experience developing firmware for tendon-driven or BLDC-actuated robotic hand or finger mechanisms

Contributions to open-source RTOS or embedded middleware projects (Zephyr, NuttX, or similar)
