Description

Leidos is seeking a Senior Embedded Software Engineer to support the development of mission-critical embedded software and firmware for missile defense systems. The selected candidate will contribute to the design, development, integration, and demonstration of advanced software capabilities in a fast-paced engineering environment. This role requires close collaboration with integrated engineering teams and strong technical communication skills to support delivery of high-quality software solutions to customers.

Primary Responsibilities

• Conceptual design across the full stack of software for airborne systems, embedded software architectural design, code implementation, team peer review, unit testing, cohesive integration of loosely coupled software modules within subsystems and across distributed networks, use of DevOps and CI/CD pipelines, and development of software tools, harnesses, and infrastructures to support a fully integrated solution.


• Leading and contributing to the design, development, testing, troubleshooting, and debugging of embedded software systems.


• Frequent and direct communication with customers, end users, internal stakeholders, and team members.


• Applying established software engineering principles, standards, and best practices throughout the full software development life cycle (SDLC) including but not limited to: (a) software requirements analysis, (b) hardware compatibility analysis, and (c) development of tools and software products that support infrastructure, platform design and system maintenance.


• Recommending and implementing new technologies, tools and standards to enhance software engineering practices, which align to organizational goals.


• Leading and mentoring other team members, contributing to the delivery of complex projects, all the while aligning with technical strategy and execution plans.


• Demonstrate initiative in identifying improved development workflows, tools, and engineering practices, including emerging AI-enabled development capabilities.

Basic Qualifications

• Bachelor's degree in Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Aeronautical Engineering, Mathematics, or related technical discipline from an accredited institution, with an overall GPA of 3.0 or higher.
