Senior/Staff Software Engineer - Frontend at Maxima in San Mateo, CA

Company Description

At Maxima, we’re building an agentic AI platform to automate enterprise accounting.

Our system handles high-volume financial data, complex accounting workflows, and robust executions that must be accurate and reliable.

We’re tackling some of the hardest problems in enterprise automation, and we’ve assembled a world-class engineering team with staff-level talent from Robinhood, Glean, Google, Netflix, and Meta. Maxima is backed by top-tier investors including Kleiner Perkins and Redpoint Ventures, and we’re trusted by category-defining customers like Scale AI and Rippling.

Role Overview

As a senior/staff frontend engineer, you will own the user-facing surfaces of our enterprise accounting automation platform.

Notable challenges include:

• Designing and building UX patterns for agentic workflows
• Architecting performant, data-dense interfaces for complex financial workflows
• Building and scaling our design system and component architecture across an expanding product surface
• Translating intricate accounting workflows into clean, intuitive interfaces that's enterprise user friendly

You'll own major product surfaces end-to-end and work closely with customers to shape what we build. Beyond technical excellence, we value frontend engineers who care deeply about craft, performance, and the details that separate good products from great ones.

What We're Looking For

• Typically 5+ years building production web applications at high-growth companies
• Deep expertise in modern frontend — React, TypeScript, and the broader ecosystem
• Strong eye for design and interaction details
• Experience building data-dense interfaces or streaming/agentic UX patterns is a strong plus
• Comfort going beyond the frontend when needed — touching APIs, schemas, or backend code to ship a feature end-to-end
• Loves in-person culture, we are 5 days a week in office in downtown San Mateo

• Be a core part of a mission-driven startup looking to transform accounting processes.
• Work in a fast-paced environment where your decisions directly impact product direction and company growth.
• Opportunity to grow with the company and build a technical team from the ground up.
