Job description

• 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

Benefits

• Equity: Substantial incentive stock plan for all salaried employees


• Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans


• Flexible PTO policy


• Vision: 100% coverage + 50% for dependents


• Dental: 100% coverage, orthodontia extra, 50% for dependent


• Voluntary Life, Accident, Hospital, Critical Illness, Commuter and FSA are offered as employee contributed benefits


• Team-bonding company outings, happy hours and in-person camaraderie


• Beautiful El Segundo headquarters close to the Pacific Ocean

• Must be willing to work extended hours and weekends as necessary to accomplish our mission


• 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


• Strong written communication skills, producing documentation that is respected by engineers and actionable for executives


• 6+ years in technical program or project management, including infrastructure and security programs


• Breadth of IT experience


• 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


• Regulated environment experience (nuclear, defense, aerospace, life sciences, or similar) including work under compliance frameworks


• 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


• Foster a culture of influence, effective stakeholder management, and teamwork


• Delivered IT infrastructure into new construction or facility buildouts: manufacturing, industrial, healthcare, or multi‑site commercial


• Familiarity with CMMC, NIST SP 800‑171, or FedRAMPDOE, national laboratory, or ITAR‑controlled environment experience


• Exposure to OT and IT convergence in manufacturing or plant settings


• Site decommissioning or IT asset disposition experience


• PMP or equivalent formal project management training


• Multi‑site or multi‑state portfolio experience with regular travel
