What We Do
Rillet serves accounting and finance teams, the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight.
Rillet is the Agentic ERP built for modern finance teams. We help companies automate the most critical parts of finance, from closing the books and recognizing revenue to consolidating entities and reporting to investors. More than 600 companies run on Rillet, including Mercor, Scribe, and Function Health, and we partner with leading accounting firms including EY and KPMG.
We’re building in one of the largest software markets in the world, with the momentum to match. Rillet has raised more than $200M, is valued at $1B, and is backed by Sequoia, a16z, ICONIQ, Bain Capital Ventures, Oak HC/FT, and other leading investors. We’re using that backing to build the financial infrastructure for the next generation of companies and help every business run its 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.
The people who thrive at Rillet do not wait for assignments. They internalize the mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for.
Our work revolves around our customers. The people who succeed here are energized by delivering what matters most, even when it was not part of the original plan.
Rillet is built on deep accounting expertise, and it takes people from many disciplines to build a category-defining company. You do not need to be an accountant to thrive here. You do need to care deeply about the problems we solve and the impact our customers can create. Together, we combine the precision of accounting with the speed, creativity, and ambition of AI-native software to power the financial core of the world’s fastest-growing companies while redefining what finance teams should expect from their software.
Who We Need
Experienced software engineers who drive real business impact - whether that's owning a product capability, leading a technical system, or shaping engineering strategy across teams. You've scaled through high-growth, you partner well cross-functionally, and you care about how a team builds, not just what ships.
We're building industry-defining accounting and finance software. We want engineers who bring a point of view to the work.
Our Tech Stack: Svelte 5/TypeScript frontend, Kotlin + Spring Boot backend, PostgreSQL, AWS. We're AI-native - meaning thoughtful application, not outsourced thinking. Our engineers still reason from first principles; AI helps with execution.
We’re looking for teammates who are based near our New York City or San Francisco offices, or open to relocating. Our hybrid schedule brings the team together in person on Tuesdays and Thursdays, plus one additional flexible day each week. Some roles may spend more time in the office depending on the needs of the team.
What You'll Do
Own features and systems end-to-end across the full stack, from backend architecture to the interfaces users interact with every day
Partner with product, design, and finance experts to shape what we build - advocating for the right technical tradeoffs and keeping the customer perspective central
Raise the bar for engineering quality: continuous delivery, test-driven development, production reliability, and a culture of ownership
Grow the team around you through code reviews, mentorship, and hands-on collaboration
Who We're Looking For
5+ years of software engineering experience, with a track record on complex, large-scale projects
Strong backend fundamentals and willingness to jump into frontend when needed
Comfortable making technical decisions and navigating hard tradeoffs at whatever scope your role demands
Strong product instincts - you think about user impact, not just technical correctness
Energized by building in a fast-moving environment where the playbook is still being written
Bonus Points
Experience in fintech, ERP, or accounting software
Hands-on experience with Kotlin, Java, or TypeScript,
Familiarity with enterprise readiness (SOC 2, SSO/SAML, audit logging, or similar)
The expected base salary range for this role is $170,000-$350,000 in New York City and San Francisco. Final compensation within this range will depend on factors including skills, experience, qualifications, and the scope of the role. This role is also eligible for equity and benefits.
