Description

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.

Responsibilities

  • 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

Requirements

  • 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)

Compensation range:

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