Senior Tax Manager

We're building the creative layer for modern communication. Every month, over a billion people make presentations — but the tools they use to make them haven't evolved in decades. We're changing that, using AI to disrupt a massive market.

Millions of people rely on Gamma to create, teach, and persuade, creating more than 1 million gammas every day.

We see Gamma as the next great workplace tool, combining viral B2C love with a massive B2B opportunity. We believe AI can be a true creative partner: one that understands context, clarity, and taste.

We’ve reached a $2.1B valuation
, crossed $100M in annual recurring revenue
, and have been profitable since 2023.

We're an imaginative, passionate team who takes our work seriously, but not ourselves. Our culture is warm, a little quirky, and fueled by curiosity.

You’ll build and lead the tax function at Gamma, reporting to the Director of Accounting. With tens of millions of users worldwide and a fast-growing B2B business, our tax footprint is expanding quickly across global indirect tax, income tax provision, corporate returns, and local filings. You’ll be our dedicated tax owner: shaping strategy alongside the Director of Accounting, running the compliance calendar, and managing external advisors, all while staying hands‑on with the technical work yourself.

This is a builder’s role. We keep finance lean and put automation and AI to work wherever we can, so you’ll design tax processes and systems that scale with the business instead of scaling headcount. If you want to own a global tax function end‑to‑end, with the judgment calls, advisor relationships, and cross‑functional influence that come with it, this role was built for you.

• Lead Gamma’s tax function end‑to‑end in partnership with the Director of Accounting, owning the global tax calendar and the relationships with our external advisors
• Own global indirect tax across our self‑serve and enterprise business: US sales and use tax (nexus analysis, registrations, filings) plus international VAT, GST, and digital services tax obligations
• Manage the quarterly and annual income tax provision under ASC 740, and review US federal, state, and local corporate income tax returns and estimated payments prepared by external advisors
• Handle local and other tax obligations (franchise, property, gross receipts, business licenses), and maintain the controls, documentation, and audit support that keep the function clean
• Advise on the tax implications of international expansion, entity structuring, transfer pricing, and equity compensation as Gamma grows globally
• Build scalable tax processes and implement tax technology, using AI and automation to keep the function lean as complexity grows

Our team has a strong in‑office culture and works in person 4–5 days per week in San Francisco. We love working together to stay creative and connected, with flexibility to work from home when focus matters most.

• An active CPA license and a bachelor's degree in Accounting, Finance, or a related field, plus 8+ years of progressive tax and accounting experience spanning Big Four public accounting and in‑house industry roles
• Deep technical command of ASC 740 tax provision, multi‑state corporate income tax, and US sales and use tax compliance
• Strong working knowledge of global indirect tax (VAT, GST, digital services taxes) for SaaS or digital products sold internationally
• A builder’s mindset: you’ve created tax processes, controls, and documentation from scratch and managed external advisors to get leverage
• The range to operate both strategically and hands‑on with limited oversight, translating complex tax issues clearly for non‑tax partners, paired with genuine excitement for AI tools and a track record of automating manual work
• A Master’s in Taxation, experience with tax technology platforms like Anrok, Avalara, or Vertex, transfer pricing or international structuring experience, or time at a high‑growth SaaS or AI company (Nice to have)

The base salary for this full-time position, which spans multiple internal levels depending on qualifications, ranges between $190K - $240K plus…
