Senior DevOps Engineer

Overview:

Expression is seeking an experienced Senior DevOps Engineer to support the National Telecommunications and Information Administration (NTIA) Federal Spectrum Data Systems (FSDS) program within the U.S. Department of Commerce. The FSDS program supports the modernization of federal spectrum management systems through improved technology, automation, data integration, and interoperability. These systems help NTIA manage federal spectrum use and support essential government missions. As the DevOps lead for the program, you will design, implement, and maintain secure cloud infrastructure and delivery pipelines supporting applications, data services, and analytics across Azure Commercial, Government, and Secret cloud environments. You will work closely with government stakeholders, software engineers, system administrators, data engineers, and security personnel to move capabilities into production and keep them secure, reliable, and maintainable. We’re looking for someone who can own the work from infrastructure code through production deployment and leave behind automation and documentation the team can depend on. You will also help newer engineers grow their skills and set the standard for how DevOps work gets done on the program. Location: Washington, DC (3 days/week on-site).

• Integrate code, dependency, container image, and infrastructure security checks into delivery workflows.
• Establish repeatable release processes, approval controls, and artifact management.
• Support deployments within restricted environments, accounting for connectivity, tooling, and software dependency constraints.
• Partner with development teams to resolve deployment issues, improve delivery speed and quality, and promote consistent DevOps practices across the program.

Security & Compliance

• Implement and maintain technical controls aligned with applicable Department of Commerce, NTIA, and federal security requirements.
• Apply secure configuration baselines and STIGs where required; identify and remediate infrastructure and application vulnerabilities.

• Work with government and program security personnel to translate control requirements into practical infrastructure and pipeline safeguards.

Reliability & Operations

• Implement monitoring, centralized logging, and actionable alerts for infrastructure, containers, pipelines, and applications.
• Troubleshoot production issues, support incident response, and address root causes.
• Develop and validate backup, recovery, and rollback procedures.
• Maintain architecture diagrams, deployment documentation, and operational runbooks, and brief government stakeholders on infrastructure status, risks, and recommendations.
