## About the Role

An experienced embedded software engineer who can lead multidisciplinary engineering efforts and thrive at the hardware-software interface. You enjoy tackling complex problems, collaborating across engineering domains, and taking ownership of significant technical challenges. You communicate clearly, apply sound engineering judgment, and deliver robust solutions. Hands-on experience with embedded software-particularly C/C++, FPGA software development, and hardware/software integration-is highly valued., * Bachelor's Degree in a STEM (Science, Technology, Engineering, or Math) field from an accredited institution with 5 years of professional experience, or Master's degree in a related field with 3 years of professional experience.

 * Proficiency in C++.
 * Experience developing embedded systems-level software, including low-level or hardware-near applications.
 * Experience with embedded Linux development and system bring-up.
 * Experience working with hardware communication protocols such as PCIe, SPI, and I2C.
 * Demonstrated experience leading or coordinating technical activities across a cross-functional engineering team.
 * Active DoD Secret security clearance with the ability to maintain the clearance.
 * Willingness to work in a classified environment.

Desired Skills

 * Experience leading multidisciplinary development teams spanning Software and FPGA/Firmware.
 * Experience with Earned Value Management (EVM) and/or Cost Account Management (CAM).
 * Experience developing and tracking engineering estimates, schedules, milestones, and technical performance metrics.
 * Experience gathering and reporting metrics for Agile stories, work packages, milestones, and program deliverables.
 * Experience communicating technical status, risks, issues, and recovery plans to customers and program leadership.
 * Experience with software development in Bare-Metal C/C++ for low-level or hardware-near applications.
 * Experience developing software test plans, procedures, and documentation supporting software verification.
 * Experience supporting integration and verification efforts for embedded platforms.
 * Experience with FPGA/Firmware development, integration, or verification.
 * Experience with hardware/software co-design and hardware/software integration.
 * Experience with CI/CD pipelines and automated software build, test, and deployment environments.
 * Experience working in secure, classified, regulated, or safety-critical development environments.
 * Experience with Agile development methodologies and tools for planning and tracking technical work.
 * Strong technical communication, collaboration, and mentoring skills.
 * Experience identifying and managing technical, schedule, cost, and integration risks.
 * Experience presenting technical status and program metrics to customers and senior leadership.

## Description

* Lead/co-ordinate a cross-disciplinary team to plan, integrate, and deliver embedded processing capabilities.
 * Own the full software lifecycle: requirements, design, implementation, integration, verification, and sustainment.
 * Develop and maintain C++ code for secure embedded applications.
 * Write low-level software that interfaces with hardware, FPGA/firmware, and protocols (PCIe, SPI, IC).
 * Support hardware/software integration, system bring-up, and lab debugging.
 * Manage technical dependencies between Software and FPGA/Firmware teams.
 * Produce estimates, schedules, milestones, and work products; track and report engineering metrics.
 * Communicate status, risks, and recovery plans to leadership and customers.
 * Apply Earned Value Management (EVM) and Cost Account Management (CAM) for program forecasting.
 * Identify & mitigate technical, schedule, resource, and integration risks.
 * Maintain/expand CI/CD pipelines for secure software delivery.
 * Collaborate with systems, hardware, test, cyber, and program-management teams to deliver prototypes and production-ready systems.
 * Ensure solutions meet security, reliability, performance, quality, and program requirements.
 * Mentor junior engineers and contribute to process improvements.
