Job description

Software Engineer - TS/SCI Required

Are you a software engineer who thrives on building robust, scalable systems? Do you enjoy crafting clean, maintainable code that powers mission‑critical environments? At Expedition Technology (EXP), we’re looking for a Software Engineer with a DevOps mindset to help us design and implement services that support verification, validation, testing, and evaluation workflows for the DoD and Intel communities.

This role is ideal for someone who is a software engineer first—someone who writes production‑grade Python, understands modern software architecture, and can contribute across the stack. DevOps experience is a bonus, especially if you’ve worked with containerized deployments and CI/CD pipelines, but your primary focus will be building the services that run in our mission environments.

What You’ll Do:

• Design and implement Python‑based services and internal tools to support mission workflows
• Build scalable, maintainable, and testable software systems for verification and validation environments
• Collaborate across teams to establish best practices in software engineering, testing, and observability
• Contribute to the design and evolution of mission‑critical environments
• Support deployment and automation efforts using containerization and CI/CD tools (bonus)
• Mentor teammates and help grow engineering capabilities across the team

What You Bring:

• U.S. Citizenship
• An active TS/SCI security clearance
• Bachelor’s degree in Computer Science, Electrical Engineering, or a related field
• 5+ years of experience in software engineering with a strong foundation in Python
• Ability to write clean, modular, and well‑tested code using modern software engineering practices
• Solid understanding of software architecture, design patterns, and system integration
• Familiarity with containerization (e.g., Docker) and CI/CD tools (e.g., GitLab) is a plus
• Experience with Kubernetes is a bonus, but not required
• Familiarity with cloud platforms (e.g., AWS) is helpful, but not the primary focus
• A collaborative mindset and a passion for engineering excellence
