Role Overview
As a Firmware Engineer, you will join a cross‑functional team to develop and own firmware for Molg’s robotic microfactory systems. You will design, develop, maintain firmware, manage the full lifecycle, write real‑time C/C++ code, develop drivers, collaborate with hardware engineers, build test frameworks, interface with other systems, instrument firmware for observability, contribute to architecture, attend design reviews, and support reliable hardware integration.
Responsibilities
Design, develop, and maintain firmware for embedded systems across Molg’s robotic platforms—including motor controllers, sensor interfaces, actuators, and custom PCBs.
Own the full firmware development lifecycle: requirements gathering, architecture design, implementation, testing, and deployment to production hardware.
Write robust, real‑time firmware in C/C++ targeting bare‑metal and RTOS environments (FreeRTOS, Zephyr, or similar).
Develop and maintain drivers for communication protocols including CAN, SPI, I2C, UART, RS‑485, and Ethernet.
Collaborate closely with electrical engineers to bring up new hardware, validate schematics, and debug hardware/firmware interactions at the board level.
Build and maintain hardware‑in‑the‑loop (HIL) and software‑in‑the‑loop (SIL) test frameworks in automated CI/CD pipelines.
Partner with robotics and software engineers to define clear firmware/software interfaces and ensure reliable communication.
Instrument firmware for observability—logging, telemetry, diagnostics—to support production monitoring and rapid debugging.
Contribute to firmware architecture decisions as system complexity grows, balancing performance, reliability, and maintainability.
Participate in design reviews and bring a hardware‑aware perspective to cross‑functional technical discussions.
Qualifications
5+ years of professional firmware or embedded systems engineering experience with a track record of shipping firmware on real hardware.
Expert proficiency in C and C++; experience with Python for tooling, test automation, or scripting is a strong plus.
Deep experience with microcontrollers/microprocessors (STM32, ESP32, NXP, TI, or similar); comfortable using datasheets and reference manuals.
Hands‑on RTOS development experience—task scheduling, interrupt handling, memory management, real‑time constraints.
Solid understanding of embedded communication protocols (CAN, SPI, I2C, UART, Ethernet) and debugging with logic analyzers and oscilloscopes.
Comfortable reading schematics and working directly with hardware to resolve interaction issues.
Experience writing automated firmware tests, ideally in HIL or SIL environments; knowledge of pytest, Robot Framework, or similar is a plus.
Strong debugging skills—able to navigate from application layer down to register level.
Excellent communicator with a bias toward documentation and maintainable code.
Ability to work in person at Molg HQ in Sterling, VA.
What You’ll Get
You’ll have the opportunity to build alongside an incredible team in a collaborative, fast‑paced environment that values autonomy and impact.
