Senior Financial Analyst

Join Mozilla Finance as a Senior Financial Analyst, where you'll be responsible for strategic resource allocation and overseeing day-to-day financial operations. You'll prepare forecasts, reconcile actuals, maintain headcount and vendor tracking, and produce reporting for budget owners and the COO. This role requires a detail-driven, resourceful self-starter with strong financial analysis skills and the ability to communicate effectively with non-finance audiences.

• Prepare the Core Services forecast each cycle, build and load cost center detail in Pigment, validate inputs, reconcile against the prior cycle, and document what moved along with the drivers behind it.
• Assemble the monthly budget update, prepare variance to plan, drivers, and open items for budget owners and the COO, ready for the Finance Manager to carry into leader conversations.
• Partner with Accounting through monthly close, tie out actuals, accruals, and forecast, and resolve coding and timing issues at the source rather than correcting for them downstream.

• Bachelor's degree in Finance, Accounting, Economics, or another quantitative field, or equivalent experience
• Interest in applying AI, automation, and systems thinking to reduce manual effort in recurring finance work
• 5+ years of work experience in business unit FP&A, corporate FP&A, strategic finance, or a comparable analytical finance role, including hands-on work through a full budget and forecast cycle with close and variance analysis
• Excellent written and verbal communication skills, including the ability to explain a variance concisely to a non-finance audience
• Ability to work across functions, distilling detail into structured summaries that leaders can act on
• Advanced spreadsheet and financial modeling skills. You care about formula cleanliness, auditability, and accuracy
• Are looking to build depth across a complex portfolio before moving into a lead partnership seat
• Positive attitude, intellectual curiosity, and ability to learn quickly
• You will likely be happy and productive in this role if you…
• Enough familiarity with cloud cost or FinOps concepts to interpret reporting prepared by a technical team and question what looks off
• Grounding in accounting fundamentals, including accruals and the monthly close cycle
• Are resourceful. You identify alternative solutions and resources to continue progress
• Have low ego and high flexibility. You approach problems with your opinion on the best solution, but can accommodate and adjust to differing viewpoints
• Ability to balance multiple competing priorities and cycle deadlines without loss of accuracy
• Possess an ownership mentality. You get things done accurately with minimal oversight, proactively flagging risks to timelines
• Experience with enterprise planning tools (Pigment, Adaptive, Workday, etc.) and accounting systems (NetSuite preferred)
• Experience building automations or AI-assisted workflows within a Finance context — or the drive and resourcefulness to learn
• Experience supporting technical or G&A functions in a shared-services finance environment, where the internal team is the customer
• Experience with BI tools, SQL, Python, Power Query, or other data querying and programming languages
