Senior Product Designer

Senior Product Designer role at Rillet

Rillet serves finance teams. Our customers are the financial brains of their companies. Our mission is to help them run the numbers with impossible speed, accuracy, and insight. We are an AI-native ERP that can drive a zero-day close. Our unified source‑of‑truth data model, hundreds of best‑in‑class native integrations, automated & auditable workflows, multi‑entity consolidation, and a growing army of specialized AI agents enable us to deliver perfect customer satisfaction and ship velocity to high‑growth AI customers such as Windsurf, Postscript, and Finch.

We raise $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. Successful team members internalize a mission, design a strategy, and deliver results faster and more creatively than a manager could ask for. We value in‑person collaboration and require on‑site work Tuesdays and Thursdays (plus one flexible day) in NYC or San Francisco (or willing to relocate). Certain roles may require additional in‑office time.

You are an experienced product designer who thrives in ambiguity and sees constraints as creative opportunities. You’ve contributed to products from early stages through scale and are excited to help establish design foundations at a growing company. You balance strategic thinking with hands‑on craft and are energized by making complex financial software genuinely elegant.
