Systems Security Engineer · Denver, CO

Building secure infrastructure in air-gapped environments.

I'm Joseph — a Systems Security Engineer at Sierra Nevada Corporation, specializing in DevSecOps automation, Kubernetes orchestration, and secure cloud deployments under DoD IL-4 / IL-6 compliance. I work where most engineers can't: the disconnected side of the internet.

About the work

My path through tech started in the cockpit, not the cloud. As a US Navy Avionics Technician, I learned that systems either work or they don't — and when they don't, it matters. That mindset followed me into DevSecOps, where I now build the pipelines that move classified workloads through air-gapped Azure Government environments.

I'm certified in Security+ CE and hold a Master's in UX Design from MICA — an unusual combination that means I think about both the security perimeter and the engineer who has to live inside it. Good tooling is invisible. Good security is also invisible. I aim for both.

Off-hours, I run Fedora Aurora as my daily driver, contribute to immutable OS projects, and tinker with custom compositors. Lately I'm building aurora-niri-noctalia, a custom Fedora image combining Niri, Noctalia Shell, and Catppuccin theming.

Where I've worked

  • 2024 — Present
    Systems Security Engineer II
    Sierra Nevada Corporation · Englewood, CO

    DevSecOps automation, Kubernetes orchestration, and secure cloud deployments in air-gapped Azure Government environments under DoD IL-4 / IL-6 compliance frameworks.

  • 2019 — 2024
    Engineering & UX Roles
    Various · Industry transition

    Bridged UX research and engineering practice through Penn State (Information Sciences & Technology) and MICA (Master's, UX Design), building the design-thinking foundation that shapes my approach to secure tooling today.

  • 2015 — 2019
    Avionics Technician
    United States Navy

    Maintained and troubleshot mission-critical avionics systems on naval aircraft. Learned that uptime is measured in lives, not nines.

Let's build something together.

Open to DevSecOps and Platform Engineering roles in cleared environments — remote or Denver-area. If you're working on hard infrastructure problems, I'd love to hear about them.
