Cyber Platforms Software Engineer, Senior at 631 Booz Allen Hamilton_United States — Annapolis Junction, MD

Cyber Platforms Software Engineer, SeniorThe Opportunity:

We build software for large, fast-changing cyber problems where speed, scale, and complexity demand better tools. As a Senior Software Engineer, you’ll work across production systems used by operators, analysts, and cyber experts today, while also helping develop new capabilities from early technical concept to deployed product.

On our team, you’ll move across the stack through back-end services, data systems, user-facing tools, automation, containers, and cloud infrastructure. You’ll bring judgment to ambiguous problems, make practical technical tradeoffs, and work close to users to understand where software holds up or breaks down in real-world use.

What You’ll Work On:

• Build software that helps operators make sense of fragmented, high-volume cyber data.
• Make complex cyber workflows more reliable, observable, and repeatable at enterprise scale.
• Take new cyber capabilities from early technical concept to prototype and deployed product.
• Apply AI, analytics, and decision-support techniques to reduce analyst burden and improve operator decision-making.
• Develop orchestration and human-in-the-loop systems that help cyber teams coordinate, prioritize, and act.

This role is for engineers who want to build software that is used now and help define the next generation of cyber capabilities.

Join us. The world can’t wait.
