SteerBridge Strategies is a modern technology company delivering innovative, mission‑focused solutions to the U.S. Government and private sector. Leveraging deep expertise in federal acquisition, digital transformation, and emerging technologies, we deliver agile, commercial‑grade capabilities that accelerate operational effectiveness and drive measurable mission success.

At the core of SteerBridge is our people—especially the veterans whose leadership, problem‑solving mindset, and commitment to excellence elevate every project we support. We don’t simply hire exceptional talent; we cultivate it, creating meaningful career pathways for veterans, military spouses, and professionals who share our passion for advancing technology and strengthening the missions we serve.

SteerBridge is seeking a Security Architect to define the security architecture and compliance strategy for a mission-critical Defense Aviation platform running in AWS GovCloud for federal customers. This role owns the security blueprint—controls, identity, zero-trust access, monitoring, and authorization strategy—for environments supporting federal aviation operations.

The architect will work directly with solutions architects, security and cloud engineers, data teams, and stakeholders to translate DoD security requirements into enforceable, well-architected designs and to guide the platform toward and through authorization (ATO).

This role stays close to implementation. The ideal candidate sets security standards, designs control frameworks, reviews architectures, and guides engineers in implementing defense-in-depth and zero-trust access.

This is a hybrid position based in Vienna, VA.
