About The Position

Maxima is the first agentic AI platform for enterprise accounting. Our agents do the accounting work itself: journal entries, transaction matching, reconciliations, and flux analysis, in real time and to SOX standards. Accountants review and approve. Nothing posts without a person signing off. We remove the grind, not the human. Maxima is the first agentic AI platform for enterprise accounting. Our founders oversaw the finance org at Rubrik and built the month-end close systems at Twitter and Netflix. We've raised $41M from Redpoint Ventures, Kleiner Perkins, and Audacious Ventures, and we're backed by finance leaders at OpenAI, Rubrik, and Vanta. Maxima runs in production at Scale AI, Rippling, Glean, and SpotOn. We are early, we are growing fast, and we are hiring people who would rather build the category than join it. Here is one way to do that. We are working on some of the hardest problems in enterprise automation, with an engineering team that includes staff-level talent from Robinhood, Glean, Google, Netflix, and Meta. The system handles high-volume financial data and complex accounting workflows, and every execution has to be accurate and reliable, because the output is a company's books. As a software engineering intern at Maxima, you will work directly with our engineers, founders, and product team on the systems that automate complex financial workflows and power our agentic automation framework. This is not a shadowing internship. You will write production-quality code, sit in architectural discussions, and work with large language model integrations, workflow orchestration, and data-intensive systems, and you will see how AI and automation get applied to real enterprise problems at scale.
