We are at the forefront of developing advanced humanoid robots designed for household use. Our mission is to create an abundant supply of labor via safe, intelligent humanoids. As we transition from R&D to full-scale manufacturing, we seek an experienced Embedded Software Engineer. We are currently seeking a highly skilled and motivated Embedded BMS expert to join our team. In this role, you will be responsible for developing the next generation Battery Management System (BMS) for our biped robot NEO. Collaborating closely with other hardware- and software-teams, you will play a vital role in everything from design to mass manufacturing. The ideal candidate will have a background in developing battery systems for robotics, automotive or consumer products, with extensive expertise and experience in bringing battery development from concept to production. We are looking for individuals with hands-on experience, and a proactive "get-things-done" attitude, who excel in both long-term strategic planning and day-to-day execution of practical tasks.

What You’ll Get By Joining Our Team

  • Develop a battery system for a humanoid robot from scratch.
