Bare-Metal Embedded Software Engineer

Build firmware that runs where operating systems dont margins are tight and failure is not an option.

Leidos is seeking a Bare-Metal Embedded Software Engineer to help design and deliver the low-level firmware that powers our uncrewed underwater vehicle (UUV) platforms and supporting systems.

This role focuses on true bare-metal development on modern microcontrollers. You will work directly with hardware peripherals sensors and real-time constraints to build the foundational software that enables autonomy communications and mission execution. There is no Linux safety net here. Your code runs on the metal and must work reliably in demanding operational environments.

Youll join small focused engineering teams and contribute from early design through integration test and delivery supporting UUV programs that serve critical national security missions.

We value engineers who are curious about hardware disciplined about quality and motivated by seeing their work operate in real systems.

Responsibilities:

• Develop production firmware for UUV and embedded systems from project inception through field deployment.
• Design and implement bare-metal application software and utilities in C/C on microcontroller platforms with no operating system.
• Interface directly with hardware including sensors power systems and communication devices.
• Implement and maintain low-level drivers and peripheral interfaces including I2C SPI UART CAN and related protocols.
• Translate system and firmware requirements into clear testable embedded implementations.
• Participate in technical design and trade studies contributing to architecture and implementation decisions.
• Support integration test and evaluation diagnosing issues across software and hardware boundaries.
• Use lab instrumentation such as oscilloscopes and multimeters to debug timing signal integrity and hardware/software interactions.
• Collaborate closely with electrical systems and software engineers to deliver cohesive embedded solutions.
• Contribute to continuous improvement refining development practices tooling and documentation.

Basic Qualifications:

• Education & Experience
  Bachelors degree in Electrical Engineering Computer Science or related field with 03 years of relevant experience and strong exposure to embedded systems and hardware.
• Security Clearance
  Ability to obtain and maintain a U.S. Secret clearance (U.S. Citizenship required).
• Core Firmware Skills
  Strong proficiency in C/C for embedded systems development.
• Hardware Awareness
  Working understanding of modern microcontrollers digital electronics and safe handling of electronic components.
• Debug & Measurement Skills
  Experience using oscilloscopes multimeters and related tools for system troubleshooting.
• Linux Familiarity
  Basic proficiency with Linux command-line tools for development and build environments.
• Concurrency Fundamentals
  Basic understanding of thread-safe design and inter-task or inter-process communication concepts.
• Communication & Teamwork
  Ability to clearly communicate technical ideas designs and plans within a multidisciplinary team.
• Professional Integrity
  Demonstrated accountability reliability and respect for teammates and customers.

Preferred Qualifications:

• Microcontroller Expertise
  Experience developing firmware on the STM32 family and TI family of microcontrollers.
• Peripheral & Bus Interfaces
  Strong experience with I2C SPI UART CAN Bus and similar embedded interfaces.
• State Machine Design
  Understanding of finite state machines and their application in embedded systems.
• Software Design Practices
  Familiarity with basic software design patterns and structured embedded architectures.
• Systems Modeling
  Exposure to UML tools such as Cameo or MagicDraw.
• Agile Development Experience
  Experience working in Agile environments using tools such as Jira Confluence and Bitbucket.
• Modern Dev Environments
  Familiarity with virtualized or containerized development environments (VMware Docker).
• Code Maintenance
  Ability to diagnose debug and improve both new and legacy embedded codebases.
