Security Engineer

Bellevue Office, Sunset Corporate Campus

Armada is the hyperscaler for the edge, delivering modular AI infrastructure from first deployment to AI factory with speed, scale and sovereignty. Named one of Fast Company's Most Innovative Companies and to the CNBC Disruptor 50, Armada's solutions are deployed in over 60 countries globally for organizations ranging from energy to defense.

With nearly $500 million in funding to date, Armada is backed by leading investors including Founders Fund, Lux, BlackRock and Microsoft (M12), alongside strategic partnerships with Microsoft, Dell, Palantir, NVIDIA, SpaceX, and Skydio. We are building the infrastructure layer for sovereign and edge AI - rugged, deployable compute for customers that cannot rely on centralized cloud.

Working at Armada means taking ownership, driving autonomy, and delivering impact. You'll tackle challenges that haven't been solved before and help build something transformative from the ground up. What you do here will not only define your career but help further Armada's mission to bridge the digital divide for customers around the world.

About the Role

You will own security engineering across our Azure cloud, hybrid infrastructure, and edge computing platform. The work is hands-on: building detections, testing our own applications, hardening Kubernetes, and putting controls into CI/CD. You will also help define how we secure AI/ML workloads running at the edge.

Location: This role is office-based at our Bellevue, Washington office.
