Posted on Monday, December 11, 2023

Apptronik is building robots for the real world to improve human quality of life and to help solve the ever-increasing labor shortage problem. Our team has been building some of the most advanced robots on the planet for years, dating back to the DARPA Robotics Challenge. We apply our expertise across the full robotics stack to some of the most important and impactful problems our society faces, and expect our products and technology to change the world for the better. We value passion, creativity, and collaboration to help us overcome existing technological barriers in the industry to create truly innovative products.

You will join a team developing a state-of-the-art general-purpose robots designed to operate in human spaces and with human tools. It is designed to work alongside humans, mobilize to human spaces, and manipulate the world around it.

We’re seeking a Sr. Firmware Engineer with an interest in developing flexible and robust software for robotic systems. As a Firmware Engineer at Apptronik, you will be responsible for developing and maintaining the firmware running on our embedded actuator controllers. This includes design, implementation, optimization, and testing of sensor drivers, comms protocols, filters, and real-time feedback control systems. Additionally, you will assist with the development and execution of bring-up processes, system integration, validation, and debugging embedded controller and actuator hardware as it comes online. The embedded actuator controllers are a core component enabling Apptronik robots, including humanoids and mobile manipulators, to perform useful labor tasks across a variety of different applications.
