Software Engineer

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.

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 building the future of accounting and finance software at Rillet, and we need engineers who are hungry to grow and make an impact early. As a fullstack engineer on one of our product teams, you'll own real features from day one, working alongside our CTO, product, and design to build software that finance professionals actually love to use.

We're an AI-native company, and we expect our engineers to bring that same mindset to how they work. If you're energized by using AI to move faster and solve problems differently, you'll fit right in.

We're looking for teammates within commutable distance of our NYC or San Francisco offices (or willing to relocate). Team members work in-office Tuesdays and Thursdays, plus one additional flexible day.

• Own features end-to-end across the full stack, from backend systems to the interfaces users interact with every day.

• Collaborate closely with product, design, and finance experts to shape what we build, not just how we build it.

• Ship high-quality software through continuous delivery, test-driven development, and a strong sense of ownership in production.

• 2+ years of software engineering experience with a track record of shipping in a product engineering environment

• Pragmatic problem solver who thinks about user impact, not just technical correctness

• Actively incorporates AI tools into your day-to-day workflow, not just as a productivity shortcut but as a way to tackle problems differently

• Hungry to learn, grow fast, and contribute in a collaborative, high-bar engineering environment

• Background in fintech, ERP, or accounting software

• Room to Grow: We're building a team of ambitious, high-performing people who will grow with the company. As Rillet scales, so will your role, responsibilities, and compensation.

• 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.

• Build Real Connections: Great work happens when people connect. Join us for team offsites in incredible locations, our team has bonded everywhere from New York and San Francisco to Toronto, Italy, France, and beyond.
