Senior Firmware Engineer – Hands

Job description

We are seeking a Senior Firmware Engineer to help develop firmware for the dexterous hands of our humanoid robots. You will collaborate with our existing hands firmware team to implement, test, and debug the embedded software that drives our in-house hand designs, including motor control, sensor integration, and the real-time communications that connect the hand to the rest of the robot. You will work closely with mechanical, electrical, and systems engineers as the hand evolves from prototype to production, contribute to hardware bring-up, and help build out HIL and SIL tests for hand firmware.

Apptronik is a human-centered robotics company developing AI-powered robots to support humanity…

Job responsibilities

  • Collaborate with the hands firmware team to develop, deploy, and maintain firmware for in-house dexterous hand designs, including motor control, sensor I/O, and real-time communications.
  • Work closely with mechanical engineers as the hand design evolves; ensure firmware tracks the mechanical design and exposes the right interfaces for tuning and validation.
  • Develop firmware for distributed embedded networks that connect multiple MCUs. ● Help shape and execute the Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) testing strategy to validate hand performance,…
  • Work with cross-functional engineering teams to bring up hand hardware from prototype through production.
  • Participate in code reviews, design reviews, and pair debugging, learning from and contributing alongside senior engineers.
  • Contribute to discussions on tooling, processes, and patterns, with guidance from more experienced engineers.

Job requirements

  • Experience with humanoid robotics, prosthetics, dexterous manipulation, or other compact electromechanical systems.
  • Experience with EtherCAT for real-time embedded communications.
  • Experience developing in C and C++ for TI C2000 microcontrollers.
  • Familiarity with safety-critical embedded system design standards, including MISRA C and ISO 26262.
  • Exposure to Agile workflows, including sprint planning, design reviews, and code reviews.
  • Experience integrating tactile, force, or position sensors into embedded systems. ● Familiarity with model-based design tools (e.g., MATLAB/Simulink) for control design and code generation.
  • Contributions to firmware tooling, build systems, or developer infrastructure.
  • Familiarity with real-time embedded firmware concepts and an eagerness to develop hard real-time skills.
