About the Role
We're seeking a Senior Product Finance Manager to serve as the finance business partner to our CTO organization (Product, Engineering, R&D). This is a senior individual contributor role with high visibility to executive leadership and potential to build a team as we scale. This is a rare opportunity to build product finance infrastructure from the ground up and directly shape how we allocate capital across our evolving product suite. You’ll partner with leaders across Product, Engineering, R&D, GTM, and Operations to drive decision-making with clear unit economics, investment rigor, and pricing discipline. You thrive in ambiguity, bring structure to complex trade-offs, and can translate technical and financial drivers into clear recommendations for senior stakeholders.
Responsibilities
Act as the primary finance partner to the CTO organization (Product, Engineering, R&D), embedded in planning, prioritization, and major investment decisions
Lead business cases and driver-based models for new product launches, major feature investments, and launch readiness, including revenue potential, COGS impact, and margin outcomes.
Support investment gate materials (scenarios, sensitivities, and risks) and make recommendations for leadership.
Define and operationalize KPIs for evaluating product performance: unit economics, SKU-level profitability, pricing sensitivity, and contribution margins across our evolving product portfolio
Partner with Engineering leadership to understand and forecast key cost drivers (compute, infrastructure, vendor costs) and translate them into financial planning assumptions
Lead annual planning and forecast cadence for the CTO org: budget, headcount, prioritization, and productivity assumptions.
Partner with Product and GTM on pricing/packaging for new and existing offerings, ensuring value delivery aligns with value capture and cost structure
Collaborate with Analytics and DevOps to define KPIs and ensure adoption of reliable reporting (clear definitions, single source of truth, decision-ready dashboards).
Support the CFO and executive leadership on strategic initiatives
Skills & Experience

Advanced Excel/Sheets and comfort with BI tools (Looker, Omni, Tableau, etc.); SQL is a strong plus
Outstanding communication and stakeholder management skills with senior technical and GTM stakeholders, as well as non-finance audiences
Track record of operating in fast-paced, high-growth, VC-backed environments
Strongly Preferred
Understanding of cloud infrastructure and variable cost structures
Prior exposure to multi-product portfolio management and product-led growth motions
Experience scaling finance processes through periods of rapid organizational growth
