Status Active Location NY Location Country United States Location Region Location City New York City Description The  Role This is the most strategic commercial finance role in the team. You'll be the finance partner to ATG's Digital leadership team and the product and data organization, sitting at the intersection of product strategy, marketplace economics, and financial performance. Your job is to connect what the product team builds to the financial outcomes it creates.

When aproduct experiment improves conversion by 50 basis points, you're the person who translates that into incremental revenue, validates it against actuals, and helps the business decide where to invest next.

When the team is evaluating whether to prioritize search improvements or shipping expansion, you bring the financial lens that turns a product debate into an investment decision.

You'll also oversee a Commercial Finance Analyst who covers A&A commercial performance, giving you a small team that spans the full A&A growth story — from product investment decisions through to commercial execution and revenue delivery.

This role requires someone who is as comfortable with Amplitude experiment data and product metrics as they are with a P&L. If you've only ever worked in traditional finance, this probably isn't the right fit. If you've worked at the intersection of product, data, and finance in a technology or marketplace business, this is exactly what we're looking for.

What Sets This Role Apart This isn't a traditional FP&A role with a product label attached. You'll be embedded in ATG's product and data ecosystem, working with experiment data, marketplace dynamics, and buyer/seller economics every day. The closest analogy is a "product finance" or "strategic finance" role at a high-growth marketplace — but with the stability and complexity of a listed company.
