## About the role

Radiant is seeking a Technical Program Manager, IT & Security, to own visibility and delivery across our IT and security portfolio: eight concurrent programs across three states, including a reactor program at Idaho National Laboratory, a fuel facility and manufacturing plant in Tennessee, warehouse and office buildouts in Los Angeles, a site decommissioning, and a CMMC and NIST SP 800-171 compliance program spanning all of it.

## What they're looking for

- 6+ years in technical program or project management, including infrastructure and security programs
- Delivered IT infrastructure into new construction or facility buildouts: manufacturing, industrial, healthcare, or multi-site commercial
- Hands-on Atlassian administration-built Jira projects, workflows, dashboards, and Confluence spaces that teams actually adopted, not just filed tickets in someone else's instance
- Can hold their own in an architecture review, reads and produces network diagrams, understands infrastructure and security concepts, asks the right questions of engineers without needing translation
- Keep IT scope sequenced with construction alongside the facilities PM and general contractor so structured cabling, MDF/IDF, low voltage, access control, cameras, wireless, and carrier circuits are planned into GC milestones
- Regulated environment experience (nuclear, defense, aerospace, life sciences, or similar) including work under compliance frameworks
