Full Job Description
Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond. We operate at the cutting edge of embodied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better. JOB SUMMARY We are seeking a Junior Electrical Engineer to support the design and development of audio and display systems for our next-generation Apollo robot. In this role, you will focus on the practical implementation and testing of the human-robot interface (HRI) electronics. You will work closely with senior engineers to turn concept requirements into functional prototypes, ensuring high-quality visual and auditory user experiences from an electrical engineering perspective. ESSENTIAL DUTIES AND RESPONSIBILITIES or KEY ACCOUNTABILITIES Support the design and prototyping of HRI-specific circuitry, including LED drivers, display backlight controllers, and audio front-ends. Assist in the selection of components for visual displays (LCD/OLED) and audio systems (microphones, speakers) based on project specifications. Implement and test multi-layer mixed-signal PCBAs, focusing on signal integrity for audio and display interfaces like I2S and MIPI. Execute validation and test plans (DVT) for HRI subsystems, using specialized equipment to measure audio fidelity and display performance. Collaborate with the firmware and UX teams to troubleshoot hardware-software interactions for user feedback mechanisms (e.g., audio alerts, visual status indicators). Maintain detailed documentation of design changes
