Firmware Engineer
Confirmed on the employer's own hiring board on Nov 7, 2026. First seen by Alion on Nov 4, 2026. Mirion scores A on the Alion truth index.
The Embedded Firmware Engineer I will support the development and sustaining engineering of embedded systems used in radiation measurement and medical-device instrumentation. This early-career role works at the intersection of firmware, electronics, instrumentation, and software. The engineer will begin with well-defined firmware, hardware abstraction layer (HAL), driver, debugging, test, and documentation assignments under the mentorship of a senior firmware engineer, then grow into broader ownership of embedded platforms and legacy product knowledge.
Key Areas of Responsibility
Develop, modify, debug, and maintain embedded C/C++ firmware for microcontroller-based products.
Implement well-defined firmware features, HAL components, low-level drivers, device interfaces, initialization, configuration, and error/status handling.
Support hardware bring-up and troubleshoot issues spanning firmware, electronics, communications, and host software.
Read schematics and component datasheets and use standard bench equipment such as oscilloscopes, logic analyzers, and digital multimeters.
Support serial, USB, and other embedded command/response communications between devices and host applications.
Build firmware from controlled repositories and follow established branching, peer-review, configuration-management, and release practices.
Develop and execute unit-level and firmware-level tests; support design acceptance testing, defect investigation, and regression testing.
Create clear design notes, interface documentation, test records, and change documentation for regulated product development.
Participate in design and code reviews and collaborate with electrical, software, systems, test, manufacturing, and quality engineers.
Learn existing Sun Nuclear firmware architectures and progressively assume sustaining responsibility for established products.
