Senior Frontend Engineer

What We Do

Rillet serves finance teams. Our customers are the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight.

Rillet is an AI-native ERP that can drive a zero-day close. We are different because of our unified source-of-truth data model, hundreds of best-in-class native integrations (Stripe, Ramp, Salesforce, etc), automated & auditable workflows, multi-entity consolidation, and quickly expanding army of specialized AI agents (e.g., accrual, audit, P&L flux, board decks, etc). These earn us a consistently perfect customer satisfaction score.

High-growth AI customers like Windsurf, Postscript, and Finch love our ship velocity, because their financial stack needs to scale as quickly as they do.

This huge market is ours to take. We have raised $100M from leading investors (including Sequoia, a16z, Iconiq, Oak HC/FT, and First Round) to help everyone run their numbers at the speed of AI.

Rillet’s pace is not for everyone. Intelligence is table stakes. To succeed here, you need extreme speed, agency, and flexibility.

Successful Rilleteers do not wait for assignments. They internalize a mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for.

Work revolves around our customers. Successful Rilleteers are energized by delivering the most important things, even those that weren’t in the original plan.

In this role, you do not need to be an accountant. But you do need to appreciate the value that our customers can create for their own company when we equip them with the perfect financial tools. Successful Rilleteers love powering the financial core of the world’s fastest-growing companies.

We're looking for an experienced frontend engineer to shape the user experience of Rillet's industry-defining accounting and finance software. You'll join a growing engineering team and work closely with the CTO, product, and design to build intuitive, high-performance interfaces that finance professionals love to use.

While we offer flexible work arrangements, we're building our presence in the San Francisco Bay Area and New York City. We're looking for candidates who can work hybrid (in-office at least 2 days per week) from one of these locations or are open to relocating.
