The job, in the employer's words
EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION REQUIRES U.S. CITIZENSHIP.
Role Description:
Defense Unicorns is building UDS VM, a new product that enables Mission Heroes to securely deploy, operate, and manage virtual machines alongside containerized workloads within the UDS platform.
Many mission-critical applications cannot easily move to containers because of operating system dependencies, vendor requirements, or existing approvals. Today, running these workloads on UDS often requires custom engineering. We’re building a supported, repeatable path for running VMs in secure, disconnected environments, with the security controls and evidence needed for authorization.
The work sits at the intersection of product software engineering, Kubernetes, virtualization, and security. We’re building software—not simply operating infrastructure—to make virtual machines first-class workloads within the UDS ecosystem.
As a Senior Software Engineer, you’ll shape technical decisions, independently own complex product capabilities, and collaborate across engineering, product, and UX to deliver reliable, intuitive solutions. As this new team grows, you’ll help establish strong engineering practices; one of our Senior openings also offers an opportunity to provide hands-on technical leadership.
What You’ll Work On:
- Building Kubernetes tooling and APIs for orchestrating and managing virtual machine workloads
- Building tooling to inspect, convert, prepare, and package VM images for disconnected delivery
- Integrating virtual machine workloads with UDS networking, observability, and security capabilities
- Creating VM management workflows for inventory, status, power controls, and console access
- Solving problems across VM lifecycle, persistent storage, networking, and image distribution
- Making VM deployments reproducible, secure, and supportable in air-gapped environments
- Working with Product, UX, and Mission Heroes to turn operational needs into useful product capabilities
Responsibilities:
- Own the design, implementation, testing, and delivery of complex software features and systems
- Drive pragmatic technical decisions and contribute to architecture across product components
- Proactively identify and resolve ambiguity in collaboration with Product, UX, and Mission Heroes
- Debug complex issues across Kubernetes, virtualization, storage, networking, and operating systems
- Improve the reliability, security, performance, observability, and maintainability of our software
- Review code, mentor teammates, and help establish strong engineering practices
- Document technical decisions, communicate clearly, and collaborate effectively across teams
Travel Expectations/Requirements: 5-10%
The listed responsibilities are not exhaustive and additional responsibilities may be assigned based on the evolving needs of the organization. We are seeking a dynamic individual who is able to adapt and take on new responsibilities as they arise.
Preferred Experience and Qualifications:
- 5+ years of professional software engineering experience
- Strong proficiency in Go or another modern programming language, with an interest in developing Go-based systems
- Experience designing and building software that interacts with Kubernetes or other distributed systems
- Strong understanding of APIs, system design, and software architecture
- Experience developing backend services, controllers, operators, or developer tooling
- Familiarity with Linux systems, containers, and operating system concepts
- Experience building, testing, and operating production software
- Ability to navigate ambiguity, evaluate technical tradeoffs, and independently drive complex work to completion
- Strong problem-solving skills and ability to debug across multiple system boundaries
- Excellent communication and collaboration skills, including the ability to influence technical direction and mentor other engineers
Great to Have:
- Experience with KubeVirt, QEMU/KVM, or other virtualization technologies
- Experience developing Kubernetes operators, controllers, or custom resource definitions (CRDs)
- Experience configuring, managing, or troubleshooting Windows virtual machines
- Familiarity with VM image formats, conversion, migration, and lifecycle management
- Experience with Kubernetes networking and storage
- Experience building CLI tools, particularly in Go
- Familiarity with Zarf, OCI artifacts, or software packaging and distribution
- Experience working in air-gapped, disconnected, or regulated environments
- Contributions to Kubernetes, KubeVirt, or other CNCF open-source projects
- Experience building security-focused software or integrating systems with identity, access control, and observability platforms
