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 on the AI Agents team, you will lead the building and scaling of the core agentic systems behind enterprise accounting automation: the agents that do the accounting work for our customers. You will own the full lifecycle of agent architecture, implementation, deployment, and optimization, and solve hard distributed systems and intelligent automation problems where software engineering, AI, and enterprise operations meet.
You will own mission-critical product and engineering areas, talk to customers regularly to understand what real-world requirements look like, and help drive the roadmap for the platform. We value engineers with strong technical foundations who show initiative, curiosity, and the ability to iterate quickly.
What You'll Do
- Build and evolve the agentic systems that perform and orchestrate complex accounting automation
- Scale the AI Agents platform to support large and rapidly growing enterprise workloads
- Architect durable, highly available, and scalable financial data processing layers to support the agents' work
- Build low-latency, extensible infrastructure for deploying and iterating on new agents
- Solve intricate enterprise accounting workflows through robust, composable abstractions
What We're Looking for
- Typically 5 or more years building backend systems at high-growth, high-scale technology companies
- Experience architecting, building, or maintaining AI agent harnesses and agentic platforms
- Strong familiarity with web development, relational databases, and distributed, data-intensive systems
- Ability to design, deploy, and iterate on scalable infrastructure and automation components for AI-driven workflows
- Deep interest in AI agent architectures, workflow engines, data pipelines, or mission-critical automation in domains like fintech or enterprise software
- Strong communication and collaboration skills, and an eagerness to work cross-functionally
Where and How You'll Work
This role is based in our San Mateo office. We value in-person collaboration and are in office four to five days a week for our on-site roles.
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.
Why Join Maxima
- The work. Agentic accounting is a category being defined right now, and Maxima is one of the companies defining it. The product does the accounting work itself, so what you build, sell, or deploy shows up in a customer's books
- The people. Founders who ran the finance org at Rubrik and built the close systems at Twitter and Netflix. Engineers from Robinhood, Glean, Google, Netflix, and Meta. Controllers and accountants on the team who have closed books themselves. Small teams in San Mateo and Toronto that work in the same room, say what they think, and hold a high bar
- The benefits. Competitive salary, 401(k) for US employees, unlimited PTO, lunch in the office, and commuter benefits
- The process. A person reads every application, and we tell you where you stand at every stage
