This role plays a key part in that.

You'll improve how software is built across the sector-making code simpler, reducing duplication, and helping teams follow better practices. You'll track things like how much code we have, how complex it is, and how well it's tested, then use that information to help teams improve.

You'll also focus on making life better for developers by introducing modern tools and ways of working so teams can build software more easily and quickly.

This is a chance to make a big impact by improving how software is built across many projects that support important, real-world missions.

-Hands-on experience with static analysis, code quality, and security scanning tools (e.g., SonarQube, Fortify, Checkmarx)

-Experience working in cloud environments (e.g., AWS, Azure, Google Cloud) and containerized architectures (e.g., Docker, Kubernetes)

-Knowledge of multiple programming languages and ability to work across diverse tech stacks

-Experience establishing or managing software baselines, inventories, or asset catalogs
