Project Manager - General & Administrative Initiatives

Job Summary

The Project Manager, G&A Initiatives is an internal Celldex Therapeutics hire responsible for leading implementation and improvement projects across the company's General & Administrative functions — Finance & Accounting, Human Resources, Legal & Compliance, and IT & Facilities. This role does not own the day-to-day operation of those functions; instead, it drives the projects that implement, upgrade, and optimize the systems and processes those functions rely on — from ERP and HRIS rollouts to contract management platforms to office moves and infrastructure upgrades.

The ideal candidate is a versatile project manager who can flex across functional domains, build trust quickly with non-technical stakeholders, and bring consistent PM rigor — scope, schedule, budget, risk, and change management — to every G&A initiative on their plate

• Plan and manage Finance & Accounting system and process projects — ERP implementations or upgrades, close-process automation, AP/AR system rollouts, and reporting/BI initiatives — from initiation through go-live.
• Build and maintain project plans, budgets, and resource schedules for finance-related initiatives in partnership with Accounting and FP&A stakeholders.
• Coordinate testing, data migration, and cutover activities for finance system projects, including UAT sign-off with process owners.
• Track project-level risks and controls considerations, escalating issues affecting the financial reporting or GxP-regulated control environment.

• Lead HR systems and program implementation projects — HRIS or payroll platform migrations, benefits system transitions, and performance/talent management rollouts.
• Manage project scope, timeline, and budget for HR initiatives, coordinating between HR stakeholders, IT, and outside vendors (implementation partners, brokers, PEOs).
• Drive change management and communication planning for HR project rollouts, including training coordination and adoption tracking.
• Maintain project documentation — charters, RAID logs, status reports — for all active HR initiatives.

• Manage projects supporting Legal & Compliance functions — contract lifecycle management (CLM) system implementations, GRC/policy management platform rollouts, and compliance program initiatives.
• Coordinate cross-functional input from Legal, Compliance, and outside counsel on project requirements, timelines, and approval workflows.
• Track deliverables and milestones for risk and insurance program transitions, audit readiness projects, and corporate governance initiatives.
• Maintain project-level documentation repositories, ensuring version control and audit trail for compliance-related project artifacts.

• Lead IT and Facilities projects — infrastructure upgrades, business application rollouts (ERP, HRIS, CRM, collaboration tools), office moves/build-outs, and procurement system implementations.
• Develop project schedules and budgets for IT/Facilities initiatives, coordinating internal IT staff, facilities vendors, contractors, and managed service providers.
• Manage testing, cutover, and go-live logistics for system and infrastructure projects, minimizing disruption to end users.
• Support business continuity and disaster recovery planning projects for corporate systems and facilities.

• Serve as the central point of coordination across concurrent G&A projects at Celldex, ensuring consistent PM methodology, status reporting, and stakeholder communication across Finance, HR, Legal, and IT/Facilities work streams.
• Build and maintain master project plans, RAID logs, and dashboards; report project health, risks, and dependencies to the CFO and other executive sponsors.
