Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

Mozilla Finance partners with business units to drive strategic resource allocation and financial insight across our product portfolio. Our team of analysts supports revenue and cost ownership across Search, Advertising, Firefox, Marketing, and New Products.

We're adding a commercially-minded analyst will cover three areas: New Products (revenue and costs for B2B and SaaS-type initiatives), Ads revenue analysis in partnership with our Data Science team, and Marketing cost including labor and program spend reconciliation through close.

Beyond ownership of those areas, you'll contribute to the team's broader push to standardize how we plan and report. This role reports to the Senior Director, Finance and works alongside three senior analysts.

The right person has done commercial finance in a B2B environment, is comfortable working with data scientists, and doesn't wait to be asked before making something better.

What you'll do:

Own New Products financials: Maintain the forecast for New Products revenue and costs (labor + program spend). Validate inputs, reconcile actuals through close, and document drivers. Maintain position-level detail on how labor is forecasted and reported

B2B Financial Modelling. Once a B2B deal or New Products initiative is live, maintain an ongoing financial model, updating commercial assumptions as the business evolves. Keep operating view current as actuals come in and support with ad hoc scenarios as needed.

Support Ads revenue analysis. Partner with Data Science to conduct deep-dive research into Ads revenue trends, building the analytical frameworks and recurring views that help the business understand performance and pursue growth. Translate findings into clear insights.

Marketing cost reconciliation. Support reconciliation of Marketing program spend, coordinating with the Marketing cost lead to ensure accuracy through close and flagging issues before they compound.

Drive team standardization and reporting: Help build shared processes and templates so results can be presented as a unified view.

Be a reliable business partner. Field data and reporting questions, anticipate stakeholder needs, and communicate complex information in terms non-finance partners can use — escalating items that call for a broader partnership discussion.

Apply AI and automation to recurring work: Identify opportunities to reduce manual effort across forecast, close, and reporting cycles.

What you'll bring:

Core Experience

3–5 years of experience in commercial finance, B2B finance, FP&A, or a comparable analytical finance role, including hands-on work through a full budget and forecast cycle with close and variance analysis.

B2B commercial experience required. Familiarity with revenue modeling, deal economics, or partner, SaaS, or subscription revenue models in a B2B context.

Bachelor's degree in Finance, Accounting, Economics, or another quantitative field, or equivalent experience.

Technical Skills

Advanced spreadsheet and financial modeling skills. You care about formula cleanliness, auditability, and accuracy.

Experience with enterprise planning tools (Pigment, Adaptive, Workday, etc.) and accounting systems (NetSuite preferred).

Grounding in accounting fundamentals, including accruals and the monthly close cycle.

Comfort working with data science or analytics teams. Able to interpret analytical outputs, ask the right questions, and translate findings into financial terms.

Experience with revenue analysis or commercial modeling, including reconciling actuals to forecast in a multi-product or multi-channel environment.

Interest in applying AI, automation, and systems thinking to reduce manual effort in recurring finance work.

Ability to balance multiple competing priorities and cycle deadlines without loss of accuracy.

Communication & Collaboration

Strong written and verbal communication skills, including the ability to explain a variance, a revenue trend, or a forecast assumption clearly to a non-finance audience.

Experience building effective working relationships across functions. You know when to loop people in, can adjust how you present depending on who's in the room, and back your points with both numbers and context.

Ability to distill complex detail into structured summaries that business partners and senior stakeholders can act on.

Positive attitude, intellectual curiosity, and the drive to learn a new business quickly.

Nice to have:

Experience in B2B SaaS revenue analysis, digital advertising, and search monetization

Familiarity with revenue reconciliation or commercial reporting in a multi-product environment

Experience building automations or AI-assisted workflows within a Finance context, or the drive and resourcefulness to learn.

Experience with BI tools, SQL, Python, Power Query, or other data querying and programming languages.

Success Factors

You will likely be happy and productive in this role if you…

Possess an ownership mentality. You get things done accurately with minimal oversight, proactively flagging risks to timelines.

Have low ego and high flexibility. You approach problems with your opinion on the best solution, but can accommodate and adjust to differing viewpoints.

Are resourceful. You identify alternative solutions and resources to continue progress.

Learn new businesses fast. You ask the right questions, connect dots quickly, and build credibility with stakeholders through understanding what drives their results — not just the numbers.

By the end of your first year, New Products is running on a clean forecast model, the team has at least one shared reporting process it didn't have before, and you've made the Ads revenue picture meaningfully clearer.
