Position: Systems Administrator with Security Clearance
About the Program
We are hiring for a multi-year prime contract to enhance, sustain, and secure a classified enterprise web application supporting a Department of Defense mission partner. The platform serves a large community of users and is engineered with a modern stack:
Angular/React front ends, Java/Python/Node.js services, containerized microservices, Postgre

SQL and Elasticsearch data stores, and CI/CD deployment into a government cloud environment. The program runs Agile, ships regularly, and operates under a formal Risk Management Framework (RMF) accreditation. About the Role
You will own the infrastructure that keeps our federal mission partner’s, mission-critical application running across two separate government cloud environments. This position is designated as the Information System Security Officer (ISSO) of record, making you the day-to-day security conscience of the platform in addition to its primary systems administrator.

• Maintain system documentation, security controls, and compliance/ATO documentation.

• Perform security scans and execute data ingests and test scripts supporting releases.

• Serve as the ISSO of record — owning RMF artifacts, POA&Ms, STIG application, and coordination with the government CIO on the system's accreditation lifecycle.

• Partner with developers and Dev Ops engineers to integrate security into the pipeline from the earliest stages. What You Bring

• Bachelor's degree in computer science, information systems, or a related technical field (four additional years of specialized experience may substitute).

• Experience supporting Agile software development teams.

• Background supporting Dev Sec Ops , CI/CD pipelines, and common development tools (Git, Jenkins, Jira).
