Full Job Description
V2X is seeking a talented Senior Embedded Firmware Engineer (T03) to join our Embedded Solutions team within the Engineering Solutions organization. Embedded Solutions is a cross-disciplinary core function dedicated to the design, development, and integration of secure, high-performance embedded systems that enable mission-critical defense and aerospace applications.

In this role, you will play a key part in the full lifecycle development of advanced embedded solutions based on modern microcontrollers and real-time operating systems. You will work collaboratively with experienced engineers in a multidisciplinary, matrixed environment emphasizing technical rigor, collaboration, and continuous learning. This position is ideal for motivated early-career engineers seeking to expand their impact across microcontroller-based design, real-time software, and hardware-software integration.

Key Responsibilities

  • Design, implement, and validate embedded firmware/software solutions using C (and Python), targeting ARM Cortex or similar microcontroller-based architectures.

  • Develop and integrate peripheral interfaces and device drivers for serial, Ethernet, SPI, IC, motor control, and other real-time I/O.

  • Support hardware bring-up, board-level verification, and troubleshooting, using oscilloscopes, logic analyzers, and related lab tools in collaboration with electrical and systems engineers.

  • Integrate and optimize real-time applications using RTOS or bare-metal techniques, ensuring responsiveness and reliability in constrained environments.

  • Contribute to system-level validation and test automation to ensure robust, reliable performance and compliance with requirements.

  • Prepare and maintain clear technical documentation including design records, integration notes, code comments, and user instructions in accordance with V2X processes.

  • Participate in Agile development teams-collaborate via MS Teams, Azure DevOps, and shared digital environments to deliver disciplined, high-quality engineering outcomes.

  • Engage in peer code and design reviews, share lessons learned, and support continuous improvement in product quality, safety, and engineering practice. Maintain a strong focus on disciplined execution, safety, quality, and compliance with industry standards and secure development practices


Required Qualifications

  • Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related STEM field.

  • Approximately 5-8 years professional experience developing embedded firmware or software for microcontroller- or ARM Cortex-based systems (hands-on academic, internship, or professional work considered).

  • Proficient in C (and/or C++) for real-time embedded system development; familiarity with version control and configuration management tools (e.g., Git, Azure DevOps).

  • Experience with lab-based troubleshooting, board bring-up, and using oscilloscopes/logic analyzers for hardware/software integration.

  • Ability to develop and validate peripheral/device drivers and work at the interface of hardware and software.

  • Effective communication skills, strong team orientation, and commitment to continuous technical growth.

  • U.S. citizenship required.


Security Clearance and Other Requirements

  • Ability to access systems with information restricted to U.S. citizens as required by federal contract guidelines.

  • Eligibility to obtain and maintain a U.S. Department of Defense (DoD) security clearance may be required for certain projects.


Preferred Qualifications

  • Familiarity with real-time operating systems (RTOS) such as FreeRTOS, or experience in bare-metal scheduling for embedded applications.

  • Exposure to scripting for test automation or tooling-Python preferred.

  • Knowledge of secure coding standards and industry regulations (MISRA C, DO-178C, ISO 26262, etc.).

  • Experience collaborating in Agile or SCRUM-based development teams.

  • Practical awareness of networked communications in embedded systems (Ethernet, TCP/IP, etc.).
