Job description

What We Do

Rillet serves accounting and 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 Mercor, and Function Health 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.

Who We Are

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.

Who You Are

You’re 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 you’re excited to help establish design foundations at a growing company. You balance strategic thinking with hands‑on craft, and you’re energized by the challenge of making complex financial software genuinely elegant.

We’re looking for teammates who value in‑person collaboration and are within commutable distance of our NYC or San Francisco offices (or willing to relocate). Team members are required to work in‑office Tuesdays and Thursdays, plus one additional flexible in‑office day. Certain roles may require additional in‑office time based on function.

What You’ll Do

• Partner with product and engineering to shape product direction and contribute to roadmap planning

• Help establish and evolve Rillet’s design system and design principles

• Contribute to user research initiatives that uncover user needs and validate design decisions

• Navigate user goals, business requirements, and technical constraints to create intuitive solutions for finance & accounting workflows

• Pull inspiration from various sources to invent new interaction paradigms in finance & accounting

• Collaborate with and mentor other designers as the team grows

• Stay hands‑on and contribute directly to Rillet’s UX/UI design

Who We’re Looking For

• 5+ years product design experience in B2B SaaS environments with a strong portfolio demonstrating end-to-end ownership

• Proven ability to tackle complex design problems and visualize complex systems, from financial concepts to interaction patterns

• Experience across all stages of design from discovery and research through implementation and iteration

• Strong collaboration and communication skills with ability to work effectively with cross‑functional teams and articulate design rationale

• Challenger mindset that questions assumptions and pulls inspiration from diverse sources to create innovative solutions

Life at Rillet:

• Competitive Pay & Benefits: Backed by world‑class investors, we offer strong salaries plus equity so you share in our success. We’ve got you covered with top‑tier health and dental insurance, premiums partially or fully covered for you, plus 90% coverage for dependents.

• Flexibility That Works: Take the time you need with flexible PTO and 9 company‑wide holidays. We value both the flexibility of remote and hybrid work and the creativity and energy that comes from in‑person collaboration at our hubs in San Francisco, NYC, and Barcelona.
