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 a rapidly expanding army of specialized AI agents (accrual, audit, P&L flux, board decks, etc).

This earns us a consistently perfect customer satisfaction score and keeps high‑growth AI customers like Windsurf, Postscript, and Finch excited about our ship velocity.

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, and successful Rilleteers are energized by delivering the most important things, even those that weren’t in the original plan.

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. This is a remote‑first role with the option to work from one of our office hubs in New York City, San Francisco, or Barcelona.

While we offer flexible work arrangements, we prefer people who are excited about helping us build our presence in the San Francisco Bay Area or New York City.
