Embedded Software Engineer — Firmware, Embedded, and Functional Safety

Position Summary:

We are seeking an Embedded Software Engineer to develop the low-level software that powers our robotic this role you will design implement debug and optimize real-time embedded software for custom and COTS actuators sensors communication interfaces and safety-critical subsystems.

You will work closely with electrical mechanical controls and software teams to bring up new hardware integrate embedded capabilities into the broader robot stack and mature prototypes into reliable production systems. This role is highly hands-on and best suited for someone who enjoys working close to hardware solving complex debugging problems and writing robust C/C firmware for real robotic products.

Core Responsibilities:

• Embedded Software Development: Implement and maintain C/C embedded software and firmware for motor controllers sensors power management systems and other robotic subsystems.
• Hardware Bring-Up & Debugging: Bring up new boards write and test device drivers validate peripherals and debug hardware/software issues using lab equipment.
• Real-Time Systems: Develop bare-metal and RTOS-based software for control loops safety monitoring timing-sensitive communication and resource-constrained hardware.
• Communication & Integration: Implement and validate interfaces such as EtherCAT Ethernet CAN/CAN-FD RS-485 SPI I2C and UART.
• Firmware Tooling & Quality: Build diagnostics logging test utilities and automated workflows that improve firmware reliability observability and development speed.
• Cross-Functional Collaboration: Partner with electrical mechanical controls and software engineers to define interfaces troubleshoot system issues and integrate new robotic capabilities.
• Senior Technical Contribution: Contribute to design tradeoffs code reviews planning and mentoring while remaining hands-on in implementation and debugging.

Required Qualifications:

• Experience: 3 years of professional embedded software experience including shipping robust robotics-related products.
• Technical Proficiency: Strong C/C skills for bare-metal and RTOS-based embedded systems.
• Hardware Knowledge: Deep understanding of microcontrollers onboard computers sensors cameras actuators motor controllers and fieldbus communication.
• Hands-On Debugging: Experience with board bring-up device drivers oscilloscopes logic analyzers debuggers and hardware/software integration.
• Real-Time Systems: Experience with control loops timing-sensitive communication fault handling and safety monitoring.
• Collaboration: Ability to work effectively across hardware controls and software teams in a fast-moving engineering environment.

Preferred Qualifications:

• Direct experience with robotic systems preferably humanoid robots manipulation robots mobile robots or other complex mechatronic systems.
• Experience with designing and delivering software for functional safety
• Familiarity with industrial safety standards such as IEC 61508
• Experience with EtherCAT Ethernet CAN/CAN-FD RS-485 or other industrial/robotics communication protocols.
• Experience with motor control power systems sensor integration safety systems or distributed embedded systems.
• Experience with firmware test infrastructure CI/CD diagnostics logging OTA updates or production validation workflows.
