Assistant Controller

Affinity is seeking a technically strong and operationally minded Assistant Controller to join our accounting team reporting to the Controller. We're looking for someone who started their career in the Big 4 and transitioned into corporate, bringing that foundation with them. Along the way, you’ve driven process improvements, led system implementations, and never been afraid to roll up your sleeves. You’ve also built and managed lean, high‑performing teams and know what it takes to scale people and process together. Your experience reflects where we are today as a business, and just as importantly, where we're headed. This role will be instrumental in owning our technical accounting, financial reporting, and the controls infrastructure that supports a scaling SaaS business. The Assistant Controller will take meaningful ownership of complex accounting areas across all entities, serve as a key contributor to the monthly close process, and partner with external auditors. What You’ll Own Technical Accounting: Own US GAAP research and application across revenue recognition (ASC 606), stock‑based compensation (ASC 718), capitalized software (ASC 350‑40), leases, and other areas as they arise. Close Participation: Serve as a key contributor to the monthly close process across all entities, with primary ownership of technical and financial reporting deliverables. Financial Statement Preparation: Own the preparation of monthly internal financial statements (income statement, balance sheet, statement of cash flows, and statement of equity) and full GAAP financial statements for annual reporting. External Audit: Manage the external audit relationship end‑to‑end – PBC schedules, fieldwork coordination, and auditor communication. Not just support; ownership. Equity Administration: Administer the equity program via Carta, including option grants, exercises, modifications, ISO/NSO tracking, and ASC 718 expense. Internal Controls & Policy: Design, establish, and maintain the internal controls framework and accounting policy documentation as the company scales. Systems & Process: Work across NetSuite, FloQast, Ramp, Rippling, Carta, and MonetizeNow to improve how we operate, not just to keep the lights on. What We’re Looking For 6+ years in public accounting (Big 4 or national firm) plus industry, or a longer industry track record with strong technical depth. CPA required. Demonstrated hands‑on experience with ASC 606, ASC 718, and ASC 350‑40 in a SaaS environment – not just exposure, real ownership. Experience managing an audit cycle end‑to‑end, not just supporting one. Multi‑entity and multi‑currency close experience. NetSuite proficiency; comfortable improving systems, not just using them. Strong written communication – you’ll be authoring technical memos, policies, and communications for auditors and leadership. Nice to Have Equity administration experience, ideally in Carta. Experience with FloQast or similar close management tools. Background in a high‑growth B2B SaaS environment. Work Location San Francisco – hub‑hybrid model. Team members within commuting distance are expected in‑office 2–3 days per week, typically Tuesday through Thursday. Flexibility is balanced with meaningful in‑person collaboration.
