Senior Manager FP&A

We are seeking a Senior Manager, FP&A to join our Boston-based Finance team. Reporting to the Director, FP&A, this individual will support and own planning, forecasting, and analytics across a significant portion of the Company's operating expense base, partnering directly with department leaders to translate strategic priorities into credible financial plans. This is a broad, high-visibility role with exposure to both our scientific organization and our corporate functions. You will be a core contributor to the annual planning cycle, quarterly reforecasts, monthly close, cash and runway analysis, and Board-level reporting. The scope is intentionally wide — we are looking for someone who wants to understand how the whole company works, not just one slice of it.

Responsibilities

• Own the annual operating plan, quarterly reforecasts and long-range plan for assigned areas.
• Build and maintain driver-based models for headcount, personnel costs, external spend, consumables, capital and allocations.
• Prepare monthly and quarterly reporting packages with budget-versus-actual variance analysis.
• Include forward-looking commentary on the full-year outlook.
• Contribute to cash forecasting, burn analysis and runway management.
• Support financing planning, Board materials, budget presentations and external operating expense guidance.
• Build financial models and decision support for CRO/CDMO and vendor contracts, collaborations, capital equipment, software and facilities.
• Evaluate resource allocation trade-offs across programs, platforms and infrastructure.
• Model headcount plans, compensation cycles, recruiting plans and payroll/benefits forecasts with People Experience & Operations.
• Work with Accounting on accruals, reclasses and spend validation.
• Check that expense classification follows policy and external reporting requirements.
• Improve FP&A processes, reporting templates and self-service reporting in NetSuite and planning tools.
• Support internal controls, SOX-readiness and audit requests on budgeting and forecasting.

Requirements

• Bachelor's degree in Finance, Accounting, Economics or a related quantitative field.
• 7–10+ years of progressive FP&A, corporate finance or accounting experience.
• Demonstrated ownership of multiple full budget and forecast cycles for meaningful cost centers, including direct work with senior non-finance leaders.
• Advanced Excel and financial modeling skills, able to build a clean, auditable, flexible model from a blank sheet.
• Strong command of accrual accounting and the month-end close process.

Preferred

• Biotech, pharma or life sciences experience, ideally at a clinical-stage company, with exposure to R&D cost centers.
• Also hands-on NetSuite and an EPM/planning tool (e.g., Adaptive), plus familiarity with public company reporting (10-Q/10-K, SOX, Board reporting).
