Job Description:
Senior Software Developer - TS/SCI with Polygraph
Key Skills for Success: Go Rust Systems Architecture Distributed Systems AI-Assisted Development
Your Impact
Own your opportunity to support the nation's most critical missions. We're looking for builders - engineers with the curiosity to spot problems others have learned to live with, and the instinct to reach for the latest tools, AI included, to solve them. Put your software and architecture expertise to work designing, building, and sustaining the systems that keep sensitive operations secure, reliable, and ready, and grow your career alongside a team that values iteration and shares every improvement to lift the whole group up.
Job Description
We're looking for a versatile Senior Software Developer to design, build, and deliver mission-critical software for a government customer in the U.S. Intelligence Community. This is a wear-multiple-hats role for an engineer who is comfortable across the whole stack - someone who can set the architectural direction for a system and then chase a problem through it all the way down to the kernel. You'll participate across the full software development lifecycle - designing and documenting systems, writing code and automated tests, and planning and monitoring production deployments - taking ownership of what you build, from architecture and implementation through containerized build and deployment. You'll bring modern engineering practices, including AI-assisted development, to a team that values reliability and maintainability above all. People are our advantage: we invest in your growth as much as you invest in the mission.
MEANINGFUL WORK AND PERSONAL IMPACT
Architects software systems and services end to end - defining structure, interfaces, and technology choices, and weighing trade-offs against mission requirements and constraints.
Researches, designs, develops, and modifies enterprise software and services across all phases of the software development lifecycle.
Produces architecture and design artifacts and documentation that establish patterns others build against and support long-term maintainability and evolution.
Builds production code primarily in Go and Rust, with shell/Bash for automation and supporting tooling, and writes the automated tests that keep it reliable.
Contributes to user-facing interfaces using TypeScript and React where the work calls for it.
Develops with AI-assisted and agentic coding tools (e.g., Claude Code, OpenAI Codex) as part of the daily workflow - analyzing and extending codebases, introspecting production systems, and accelerating problem-solving - while applying sound judgment about where they help and where human review is essential.
Packages, builds, and deploys software as containers within modern container-orchestrated and GitOps-driven environments, then plans, manages, and monitors production deployments - taking ownership of the reliability of what they build.
Builds internal developer tooling, CLIs, and APIs that make build and deployment workflows faster and more reliable.
Wears multiple hats across the stack - moving fluidly between application code, the container runtime, the operating system, and the kernel to debug and deliver across complex, distributed systems.
WHAT YOU'LL NEED TO SUCCEED
Bring your engineering expertise along with a drive for innovation to GDIT. The Software Developer Sr Principal must have:
Education: Technical Training, Certification(s) or Degree
Experience: 8 years of related professional software development experience.
Required technical skills: Systems-level programming in Go and/or Rust; strong Linux and shell/Bash, with working knowledge down to the kernel level; software/systems architecture and design experience; experience building secure, highly available distributed systems; building and deploying containerized software (e.g., Docker/OCI); writing automated tests; CI/CD and infrastructure-as-code; hands-on experience with AI-assisted or agentic coding tools.
Security clearance level: Must be able to obtain TS/SCI w/Poly
ship required
Role requirements: Able to architect systems and make sound technical trade-off decisions; strong ability to debug issues in complex, distributed systems; comfortable wearing multiple hats and working across the full stack, from code to kernel; able to troubleshoot and harden systems when needed; works independently under limited supervision; strong written and verbal communication; willingness to adopt and integrate AI tools into the engineering workflow.
Preferred Skills: Kubernetes (highly sought after) and GitOps-based continuous delivery with Flux or Argo CD; systems-level experience in C or C ; front-end/UI development with TypeScript and React; container tooling (Docker Compose); Renovate; experience with monitoring, alerting, and debugging large-scale distributed systems; experience building tools and APIs; open-source contribution or maintenance.
