Staff AI Engineer at Stacks

This role is based out of our Amsterdam office 🇳🇱 or London office 🇬🇧 We are an office-first company & believe great products are made when we are together. ABOUT STACKS At Stacks, we’re transforming the way finance teams approach one of their most critical processes: the monthly close. For mid to large enterprises, the close is a painstaking, manual effort that pulls finance teams away from strategic initiatives to focus on repetitive, tedious tasks. We believe this needs to change. Our vision is bold. With the power of AI, we’re reimagining the monthly close to be as simple as a single click—providing the most accurate, detailed financial insights on day one of each month. By giving finance teams their time back, we enable them to focus on high-impact, strategic work that drives their companies forward. Our team is a blend of finance, product, and technical experts from top-tier companies like Uber, Plaid, Miro, Mollie, and Bunq, united by the drive to create a game-changing solution. Based in the heart of Amsterdam, our office offers inspiring views over the iconic canals. Backed by leading VCs and executives from Stripe, Plaid, and OpenAI, we’re ready to reshape the future of finance.
