The Role 

We are seeking a highly motivated finance leader to join our team as a Sr. Manager, FP&A responsible for our hyperscaler and cloud infrastructure spend, including Microsoft Azure and Amazon Web Services (AWS). This role reports to the Head of FP&A and serves as the finance owner of one of our largest and fastest-growing cost categories. You will lead and develop a Sr. Financial Analyst who supports cloud reporting, forecasting, and optimization tracking.

You will partner closely with Engineering, DevOps, and product leadership to understand the drivers behind cloud consumption, translate technical usage into financial outcomes, and help shape our long-term hosting strategy. You will own the monthly cloud forecast and its impact across all three financial statements (income statement, balance sheet, and cash flow), and you will help Engineering identify and execute cost optimizations, including maximizing AWS credits available under our Strategic Collaboration Agreement (SCA).

Your Day to Day

• Lead, coach, and develop a Sr. Financial Analyst, setting priorities, delegating work, reviewing output, and building their skills and visibility with Engineering and Product partners.

• Own the budget, monthly forecast, and annual and quarterly outlook for Azure and AWS infrastructure spend, including the impact on the income statement, balance sheet, and cash flow.

• Partner with Engineers and developers to understand cloud usage drivers (compute, storage, data transfer, managed services, etc.) and translate them into unit economics and forecast assumptions.

• Analyze variances to budget and forecast, and review results and key drivers with Engineering, Product, and Finance leadership.

• Help Engineering identify, prioritize, and track optimization opportunities, such as rightsizing, commitment coverage (Reserved Instances, Savings Plans, and Azure reservations), architecture changes, and waste reduction, and quantify the financial benefit.

• Support the identification, tracking, and claiming of AWS SCA credits and other vendor incentives, working with Engineering, Procurement, and the AWS account team to ensure eligible credits are captured and forecasted accurately

• Model the financial implications of commitment agreements and vendor contract terms, including prepayments, amortization, and credit utilization, in partnership with Accounting and Procurement.

• Partner with Product leadership to understand the cloud cost impact of roadmap decisions, new launches, and customer growth, and provide insight into margin and gross profit implications.

• Contribute to the strategic hosting plan, including cloud mix and workload placement across providers, long-term capacity planning, and build-versus-buy decisions.

• Develop and report key metrics such as cloud cost as a percent of revenue, cost per customer or per unit of usage, commitment utilization, and optimization savings realized.

• Build and maintain financial models, dashboards, and reporting that connect cloud billing data (e.g., cost and usage reports, FinOps tooling) to the financial forecast.

• Prepare ad hoc analyses and executive-level materials for the Head of FP&A and senior leadership.

• Drive improvements to tools, systems, and processes to support timely and accurate forecasting, cost allocation, and cloud financial governance (FinOps).

What you bring to the tea

• 7+ years of experience in Finance, FP&A, or a related field, ideally within a SaaS, technology, or cloud-delivered business.

• Experience managing cloud or infrastructure budgets and forecasts, with working knowledge of AWS and/or Azure billing and pricing models.

• Experience leading, mentoring, or developing financial analysts, with a track record of delegating effectively and raising the quality of team output.

• Strong understanding of three-statement financial modeling and accounting principles, including prepaid expenses, amortization, capitalization, and cash flow timing.

• Demonstrated ability to artner with technical teams, translate engineering concepts into financial terms, and influence decisions without direct authority.

• Experience with financial planning tools and systems (e.g., Excel, ERP, and planning platforms such as Adaptive).

• Advanced proficiency in Microsoft Excel and PowerPoint; experience with SQL, BI tools (e.g., Tableau, Power BI), or cloud cost management platforms is a plus.

• Strong communication and interpersonal skills, with the ability to present complex analysis clearly to senior leaders and non-finance stakeholders.

• Ability to work effectively within tight deadlines, manage multiple priorities, and collaborate as part of a team.

• Bachelor’s degree in Finance, Accounting, or a related field; MBA, CPA, or CFA is a plus.

Nice to have

• Familiarity with FinOps practices or FinOps Foundation certification.

• Experience negotiating or modeling enterprise commitments (EDP, MACC, or similar) and vendor incentive programs such as AWS SCA.

• Experience building unit economics and COGS or gross margin models for a SaaS or platform business.
