Looking for an opportunity where your work truly matters?
At Leidos, we deliver innovative solutions through the efforts of our diverse and talented people who are dedicated to customer success, empowered to take initiative, and committed to making a difference. Our work is built on integrity, innovation, and a shared mission to do what’s right—for our customers, our teams, and our communities.
Your greatest work is ahead.
We are seeking a Software Engineer to support missile defense projects within the Ballistic Missile Defense (BMD) Simulations and Analysis Portfolio for Leidos’ Defense Systems Land Division. In this role, you will play a key part in developing high-performance applications and utilities for real-time defense systems, contributing to national security initiatives.
You’ll develop, create, and enhance both general-purpose and specialized applications. The ideal candidate is collaborative, analytical, and has a proven ability to work with technical teams to deliver robust and scalable software solutions.
Primary Responsibilities
Design, develop, troubleshoot, and debug software using C++, Java, or similar languages.
Collaborate with technical experts and end-users to enhance existing systems and develop new capabilities.
Apply sound software engineering practices to produce modifiable, efficient, and reliable code.
Create and maintain CI/CD pipelines and automated software builds.
Actively participate in Agile development activities, including Program Increment (PI) planning, feature/story refinement, sprints, demos, and retrospectives.
Develop and execute unit tests and maintain technical documentation.
Support secure, reliable, and scalable deployments across defense systems.
Basic Qualifications
Bachelor’s degree in a related field with 4-8 years of experience, or a Master’s degree with 2-6 years.
Proficient in C++ development.
Experience with Red Hat Enterprise Linux (RHEL) OS.
Hands-on experience with network programming (e.g., message generation, UDP/TCP/IP interfaces).
Familiar with unit testing and software documentation practices.
Experience developing and deploying in a CI/CD environment.
Comfortable working directly with stakeholders and government customers.
Experience in Agile team settings (e.g., PI Planning, Sprint Reviews, Iteration Retrospectives).
Active Secret Clearance required.
Full-time, on-site role—must reside in the North Alabama area.
Preferred Qualifications
Familiarity with Scaled Agile Framework (SAFe) or other Agile methodologies.
Experience with CI/CD tools such as Ansible and Jenkins.
Additional programming experience in Python or Java.
UI/UX development experience.
Proficiency with JIRA or similar project management tools.
Background in multi-core/multi-threaded programming.
Relevant experience in Missile Defense or other DoD environments.
At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”
If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
