Job summary

Radiant in El Segundo, CA is seeking a Technical Program Manager, IT & Security to own visibility and delivery across an expanding IT and security program portfolio. You will coordinate across construction, facilities, and external partners, ensuring schedules are kept, risks are tracked, and programs stay aligned with executive expectations.

You’ll produce architecture diagrams, manage Jira/Confluence workstreams, and support compliance with CMMC and NIST SP 800-171 while working 100% onsite at

Qualifications

• 6+ years in technical program or project management, including infrastructure and security programs.
• Experience delivering IT infrastructure into new construction or facility buildouts, manufacturing, industrial, healthcare, or multi-site.
• Ability to read a construction schedule, work with a facilities PM and general contractor, and know when the window for IT work opens and closes.
• Hands-on experience administering and structuring work in Atlassian tooling, building Jira projects, workflows, dashboards, and Confluence spaces that teams actually adopted.
• Ability to hold your own in an architecture review: read and produce network diagrams, understand infrastructure and security concepts, and ask the right questions of engineers without needing translation.
• Experience in a regulated environment, nuclear, defense, aerospace, life sciences, or similar, including work under compliance frameworks.
• Track record of driving accountability without direct authority, through influence, clear artifacts, and disciplined follow-through.
• Strong written communication, documentation that engineers respect and executives can act on.

Responsibilities

• Build the system of record for how IT and security programs are tracked at Radiant, standing up the tooling, cadence, and reporting that today lives across spreadsheets, inboxes, and people's heads.
• Own the operating cadence, including recurring status meetings within IT and security and cross-functional reviews with facilities, construction, engineering, and external partners; set agendas, drive to decisions, capture actions, and follow up.
• Maintain integrated schedules, dependencies, risks, and milestones across concurrent programs; know what's on track, what's at risk, and what needs escalation before anyone asks.
• Keep IT scope sequenced with construction, partnering with the facilities project manager to ensure structured cabling, MDF/IDF, low-voltage, access control, cameras, wireless, and carrier circuits are planned into general contractor milestones rather than retrofitted after drywall.
• Support the CMMC and NIST SP 800-171 compliance program alongside executives, tracking milestone plans, POA&M status, remediation coordination, evidence collection, and assessor coordination while technical control decisions remain with the security team.
• Produce technical and network diagrams, architecture documentation, 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.
