Software Engineer

Defense Unicorns is seeking a Software Engineer to join our Edge Infrastructure team, working on UDS Image Factory.

This team builds developer tooling for declaratively composing complete, mission-ready system images for air-gapped environments. These images include everything required to run — operating system, Kubernetes, applications, and site-specific configuration — packaged into a single, versioned artifact.

The work sits at the intersection of software engineering, operating systems, and infrastructure. You’ll help build reliable, repeatable systems where everything must be defined at build time and work the first time in disconnected, real-world environments.

If you’re the type of developer who enjoys running and maintaining your own Linux systems—or wants to—this role will feel like home.

As a Software Engineer, you’ll contribute to the design and development of core platform capabilities that enable secure, predictable software delivery to the edge.

• Building custom tooling that composes operating systems, Kubernetes, applications, and configuration into a single deployable artifact
• Developing and maintaining image build pipelines (container and VM/system images)
• Working with OS-level components, base images, and system configuration
• Building CLI tooling for defining and generating system variants
• Ensuring artifacts are deterministic, reproducible, and fully self-contained at build time
• Supporting software supply chain security (SBOMs, signing, provenance)
• Automating compliance requirements (e.g., STIGs)
• Enabling deployments in airgapped, offline-first, and constrained environments

• →Collaborate with Product and Engineering to build and iterate on product features
• →Translate requirements into clean, maintainable, and well-tested code
• →Contribute to system design and implementation decisions
• →Debug complex issues across application, container, and OS layers
• →Improve reliability, performance, and security of systems that support product development, validation, and demos
• →Write and maintain documentation for systems and workflows
• →Participate in code reviews and engineering best practices
• →Work effectively in a remote-first environment

• 2–5 years of software engineering experience
• Proficiency in a modern programming language (Golang preferred)
• Experience with Linux systems, containers, or working close to the OS
• Familiarity with build systems, packaging, or image creation (or strong interest in learning)
• Experience with Kubernetes or container orchestration (or strong interest)
• Exposure to CI/CD pipelines, infrastructure tooling, or platform engineering concepts
• Understanding of APIs, distributed systems, and debugging across system boundaries
• Ability to break down complex problems and deliver practical solutions
• Strong communication and collaboration skills

• Experience with software supply chain security (SBOMs, signing, provenance, etc.)
• Familiarity with compliance and hardening standards (e.g., STIG, NIST, CIS benchmarks)
• Experience working in airgapped or restricted environments
• Contributions to open source or developer tooling projects
• Familiarity with immutable / minimal OS distributions (e.g., Flatcar, Talos, Kairos)
