Senior Finance Manager, Product & Engineering

About the Role

We are seeking a Senior Finance Manager to serve as a key partner to Mixpanel’s Engineering, Product, and Design (EPD) organizations. This person will own infrastructure cost, EPD opex, and headcount planning while building scalable systems to improve visibility and decision-making, as well as the analytical frameworks that guide how Mixpanel deploys capital and allocates resources across these areas. You’ll partner cross-functionally with Engineering and Product leadership, People, and Finance to ensure investments are intentional, efficient, and aligned with long-term company strategy.

Responsibilities

• Own the Product investment envelope – Manage OpEx and headcount budgets across EPD. Ensure investments align with company strategy while maintaining efficient spend and margin targets.
• Drive rigorous workforce planning across technical and corporate teams – Build bottoms-up headcount models by function and level. Partner with Engineering leaders to sequence hiring against roadmap needs, compliance requirements, and operational scale.
• Model infrastructure and internal systems economics – Develop clear forecasting models for cloud hosting, AI/compute, internal tooling, SaaS applications, and enterprise systems. Identify optimization opportunities across both product infrastructure and corporate tech stack.
• Translate roadmap and corporate priorities into financial tradeoffs – Evaluate build vs. buy decisions, capitalizable vs. expensed R&D, and vendor investments across EPD. Provide clear recommendations grounded in ROI and long-term cost structure impact.
• Elevate budget vs. actuals rigor across the organization – Lead monthly BvA reviews for EPD. Automate reporting, improve accrual accuracy, and surface actionable insights—not just variance explanations.

We're Looking For Someone Who Has

• 8+ years of experience in FP&A or strategic finance at a high-growth technology company.
• Proven to be a partner to Engineering leaders – You’ve supported technical teams and corporate functions, understanding how product velocity and operational infrastructure translate into financial outcomes.
• Fluency in infrastructure and SaaS cost drivers – You understand cloud economics, AI/compute scaling, enterprise tooling, and how architecture and vendor decisions impact margins.
• Strong workforce planning – You’ve managed complex headcount models across multiple departments, aligning hiring pace with financial guardrails.
• Advanced financial modeling – You build scenario-driven models with clear assumptions and sensitivity analysis that stand up to executive scrutiny.
• Strong analytical judgment and the ability to identify the few variables that matter most within large and complex datasets.
• Ability to operate independently through ambiguity and bring structure to problems that do not have an established playbook.
• Excellent executive communication skills, including the ability to simplify complex financial and technical topics and develop polished, executive ready deliverables.
• A high say/do ratio, strong attention to detail, and the ability to thrive in a fast-paced environment where priorities, assumptions, and technology can change quickly.

Bonus Points For

• Hands-on experience with Pigment.
