Firmware Engineer – Hands

About this role

Apptronik seeks a Junior Firmware Engineer to develop embedded software for the dexterous hands of their Apollo humanoid robot. You'll implement motor control, sensor integration, and real-time communications while collaborating across mechanical, electrical, and systems teams to scale from prototype to production deployment.

What you'll do

• Develop and maintain firmware for in-house hand designs including motor control, sensor I/O, and real-time communications
• Implement motor control logic for small BLDC motors with current and position/torque feedback
• Design firmware for distributed embedded networks connecting multiple microcontrollers
• Develop and execute Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) testing strategies
• Support hardware bring-up and troubleshooting from prototype through production
• Monitor field performance, telemetry, and diagnostics for deployed robot hands at scale

What they're looking for

• C/C++ programming
• Embedded systems firmware development
• BLDC motor control concepts
• Real-time embedded systems
• Embedded communication protocols (SPI, UART, RS485, CAN)
• Hardware debugging (oscilloscopes, logic analyzers)
• Electrical schematic reading and interpretation
• Distributed embedded networks
