 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.
