The Sr. Manager, Project Controls - Cost is the technical and people leader accountable for cost management, forecasting, and billing governance across one or more mega-projects in Rivian’s Production Facilities portfolio.

This role owns the living control budget, cost coding and WBS, pay‑application controls, procurement cost evaluations, cash‑flow forecasts, and cost‑risk integration—ensuring that Rivian’s $1B+ per‑program CAPEX is accurately tracked, risk‑adjusted, and aligned to lender requirements.

The Sr. Manager, Cost Controls operates as the technical execution engine beneath the Director of Project Controls, partnering with the Sr. Manager, Preconstruction & Estimating and the Sr. Manager, Schedule to deliver unified, integrated financial oversight across every phase of a mega‑project. This role requires multi‑GMP, multi‑campus portfolio experience, quantitative risk integration, and lender‑grade financial and procurement controls typical of hyperscale industrial and data‑center environments.

• Direct cost and forecast responsibility over $1B in annual CAPEX, across one or more mega‑programs within Production Facilities.
• Full ownership of control budgets, forecasts, and procurement cost baselines across all project phases – FEL, design, procurement, construction, commissioning, and handover. Control estimates and classed estimates are received from and maintained in coordination with the Sr. Manager, Preconstruction & Estimating.
• Leadership of a cost controls team (cost engineers, cost analysts, project analysts) with close partnership across estimating, schedule, risk, procurement, and VDC leads to maintain integrated baselines.
• Active interface with Finance, Treasury, Internal Audit, and lenders as the primary cost counterpart.

• 10-15+ years in project controls with a primary focus on cost management, forecasting, and cost controls for industrial, data‑center, or manufacturing mega‑projects (>$1B).
• Demonstrated ownership of GMP contracts, multi‑package cost structures, pay‑application governance, and cost evaluation of bids and changes at owner‑operator or EPC/EPCM organizations.
• Proven experience managing cost controls during CMAR or GMP‑based contract delivery, including shadow estimating, trade partner bid validation, and change order audit.
• Strong background in engineering, construction management, finance, or applied mathematics; advanced degrees or professional certifications (e.g., CCP, CPC, CFA, or similar) preferred.
• Experience implementing EVMS, QCRA/QSRA, and portfolio‑level cost reporting is strongly preferred.
• Proficiency in Rivian’s controls technology stack or equivalent platforms (PMIS, ERP, Primavera P6, cost/risk tools, BI platforms).
• Cost Budget Enforcement & Baseline Management
  • Receive and operationalize the control estimate and GMP baseline; translate those baselines into the cost coding, WBS, and budget structures used to track and govern field execution.
  • Maintain the living control budget across all GMP amendments, change events, and scope revisions – ensuring real‑time alignment between the authorized budget, committed costs, and forecast‑to‑complete.
  • Lead budget reviews with PM, Engineering, and Finance; perform scope challenge and scenario analysis (scope adds/deletes, value engineering, alternates) to support change decisions and protect budget integrity.
  • Translate risk updates into forecast and contingency recommendations tied to quantitative risk outputs (QCRA/QSRA) and procurement risk such as market movement, vendor performance, and commercial terms.
• Cost Management, Invoicing & Forecasting
  • Design and operate the cost…
