Senior Technical Program Manager (Security & IT)

• 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
• We have strong technical leaders on each effort. This role exists to see the whole portfolio, keep it visible, and hold teams to their commitments
• You won’t write the SSP or design the network; you’ll keep the people who do aligned, unblocked, and delivering against a schedule everyone can see. You’ll represent IT leadership in meetings we can’t attend, and be the reason nothing quietly slips
• Build the system of record for tracking IT and security programs, including the tooling, cadence, and reporting
• Own the operating cadence: recurring IT and security status meetings plus cross-functional reviews with facilities, construction, engineering, and external partners; set agendas, drive to decisions, capture actions, follow up
• Maintain integrated schedules, dependencies, risks, and milestones across all eight concurrent programs; know what is on track, what is at risk, and what needs escalation before anyone asks
• Produce network and architecture diagrams, project charters, status reporting, and executive summaries
• Escalate slipping commitments and unresolved blockers to the VP of IT and VP of Cybersecurity early enough to act on them, and represent IT leadership in meetings they cannot attend
• Support the CMMC and NIST SP 800-171 program alongside executives: milestone plans, POA&M status, remediation coordination, evidence collection, assessor coordination; technical control decisions stay with the security team
• First 90 days: inventory all eight programs and their owners, stand up the Jira and Confluence structure, publish the first integrated portfolio schedule, and establish the recurring reporting cadence
