We are seeking a highly skilled and experienced Senior Embedded Software Engineer to join our dynamic team. You will play a critical role in developing, optimizing, and maintaining the embedded systems that power our robots. This role involves working on real-time operating systems (RTOS), low-Level firmware, and communication protocols to enable precise motor control, sensor integration, and robust system performance.

Key job responsibilities
- You will develop and maintain firmware for robotic control platforms, ensuring reliability and performance.
- You will design, implement, and optimize software for real-time operating systems such as FreeRTOS, ThreadX, or Zephyr.

- You will design and implement communication protocols over CAN and RS485 for motor control, sensor data acquisition, and power management.

- You will analyze and optimize system performance, including timing, resource usage, and latency, and conduct testing using scripting languages like Python for automated testing and data analysis.

- You will work closely with hardware and robotics engineers to integrate sensors, actuators, and power systems.

- You will troubleshoot and resolve hardware and software issues using debugging tools and techniques.

- You will create clear, concise documentation for firmware designs, APIs, and test procedures.

About the team
Fauna Robotics, an Amazon company, is building capable, safe, and genuinely delightful robots for everyday life. Our goal is simple: make robots people actually want to live and interact with in everyday human spaces.
We believe that future won’t arrive until building for robotics becomes far more accessible. Today, too much effort is spent reinventing the fundamentals. We’re changing that by developing tightly integrated hardware and software systems that make it faster, safer, and more intuitive to create real-world robotic products.
Our work spans the full stack: mechanical design, control systems, dynamic modeling, and intelligent software. The focus is not just functionality, but experience. We’re building robots that feel responsive, expressive, and genuinely useful.
At Fauna, you’ll work at the frontier of this space, helping define how robots move, manipulate, and interact with people in natural environments. It’s an opportunity to solve hard problems across hardware and software with a team focused on making robotics accessible and joyful to build.
If you care about making robotics real for everyone and building systems that are as delightful as they are capable, we’re interested in hearing from you.
