EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION REQUIRES U.S. CITIZENSHIP.

Role Description

Defense Unicorns is seeking a Senior Software Engineer to join our Ark team, building an AI-native software development product that helps Mission Heroes create, package, and deliver secure applications into mission environments.

Ark bridges the gap between creating software and making it deployable. While AI coding tools make software development increasingly accessible, delivering applications into secure, regulated, and disconnected environments still requires specialized engineering expertise. Ark combines AI-driven workflows with UDS tooling to automate application development, packaging, validation, and delivery preparation.

This is an opportunity to help shape a rapidly evolving product at the intersection of AI, software engineering, and secure software delivery. You’ll work on complex challenges involving AI agent orchestration, isolated development environments, automated validation, and integrating AI capabilities with deterministic systems that produce reliable, deployable software.

As a Senior Software Engineer, you’ll help shape the technical direction of Ark, own the design and delivery of complex capabilities, and collaborate with Engineering, Product, UX, and Mission Heroes to turn challenging customer problems into intuitive, reliable solutions. You’ll have opportunities to influence architecture decisions and help establish engineering practices as the product evolves.

• Integrating UDS packaging, Kubernetes, and software delivery tooling into automated development workflows
• Building systems that manage persistent application state, development workflows, and asynchronous execution
• Developing automated testing and validation capabilities to ensure generated software and UDS packages are secure and deployable
• Collaborating with Product, UX, and Mission Heroes to turn complex software development and delivery challenges into intuitive product experiences
