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).
