Senior Technical Program Manager, Security & IT

Radiant Industries•El Segundo, CA

1d•Onsite

About The Position

Radiant is seeking a talented Technical Program Manager, IT & Security, to own visibility and delivery across our IT and security program portfolio. You will track eight concurrent programs spanning three states: 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 running across all of it. We have strong technical leaders on each effort. What we don't have is one person who can see the whole portfolio at once, keep it visible, and ensure teams meet commitments. In this role, you won't write the SSP or design the network. You'll make sure the people doing that work are aligned, unblocked, and delivering against a schedule everyone can see. You'll represent IT leadership in meetings we can't attend, and you'll be the reason nothing quietly slips.

Requirements

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 commercial.
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.

Nice To Haves

Familiarity with CMMC, NIST SP 800-171, or FedRAMP.
Experience in DOE, a national laboratory, or ITAR-controlled environments.
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.

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.
