About The Position

We are redefining how cryptographic keys and codes are developed, generated, and distributed to secure the nation’s most sensitive data. Our mission is to ensure the safety of our country, our families, and our allies by delivering secure cryptographic management and provisioning solutions that protect critical information systems. We aim to eliminate reliance on legacy and unsustainable infrastructures by introducing a scalable, system-of-systems architecture that enhances operational security, streamlines automated processes, and reduces human intervention. By integrating cutting-edge technology and automation, we strengthen the efficiency, sustainability, and resiliency of Mission Essential Functions (MEFs).

How We Meet the Challenge:

We bring together exceptional engineers and equip them with modern tools, trusted methodologies, and the freedom to innovate. Through a Secure Development to Operations (SecDevOps) approach, we continuously develop, test, and deliver software capabilities across multiple environments to ensure secure, reliable, and maintainable solutions. Our teams embrace Agile development principles aligned with the Scaled Agile Framework (SAFe), maintaining a prioritized backlog of Infrastructure, Network, and Platform (INP) development tasks to incrementally deliver high-value outcomes. By fostering collaboration, automation, and iterative improvement, we create secure systems that evolve with the mission and stand resilient against emerging threats.
