Senior/Staff Software Engineer

About the role

ABOUT MAXIMA

Nobody went into accounting to spend the first week of every month matching transactions by hand. Maxima was built so they don't have to. Our agents do the accounting work itself: journal entries, transaction matching, reconciliations, and flux analysis, continuously and with a full audit trail. Accountants review and approve. Nothing posts without a person signing off. We remove the grind, not the human.

Maxima is the agentic AI platform for enterprise accounting. Our three co-founders scaled finance at Rubrik from $5M ARR to a $15B NYSE IPO, built the reconciliation and billing systems behind Netflix's $32B in annual revenue, and built AI infrastructure serving two billion monthly users at Meta. We've raised $41M from Redpoint Ventures, Kleiner Perkins and Audacious Ventures, joined by former BlackLine executives and the CFOs of Rubrik and Vanta. To date we've processed more than $400B across 350M transactions at 100.00% accuracy, for customers including Scale AI, Rippling, Glean, Zendesk, Handshake, Zip, and Decagon.

We're early and moving fast. The playbook here gets written, not inherited, and the person closest to the work makes the call. We're looking for people who build from first principles and hold themselves accountable for what actually lands — people who'd rather build the category than join it. Everything you need to know is below.

THE ROLE

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 Senior or Staff Engineer, you will drive initiatives with broad business and technical impact. The role is not tied to a single area: senior and staff engineers here take on our most important and complex problems, own major product and engineering areas, and work directly with customers. Beyond technical excellence, we value engineers who are curious and take initiative.

WHAT YOU'LL DO

- Build the agentic systems that power real-world enterprise accounting automation

- Scale the platform to support large and growing enterprise workloads

- Architect a durable and scalable financial data processing layer

- Build the infrastructure that powers our agentic systems

- Solve intricate accounting workflows through clean and robust abstractions

WHAT WE'RE LOOKING FOR

- Typically 5 or more years building systems at high-growth companies

- Strong familiarity with web development, relational databases, and distributed systems

- A record of owning a product or engineering area end to end and driving initiatives that cut across teams

- Ability to design, deploy, and iterate on infrastructure that has to be accurate and reliable under high-volume financial data
