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 AI-native 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.
This huge market is ours to take. We’ve raised $200M+ from Sequoia, a16z, ICONIQ, Bain Capital Ventures, Oak HC/FT, and other leading investors 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
We’re looking for a Design Engineer who sits at the intersection of design and engineering—someone who cares as much about pixel-perfect details as about clean, performant code. This isn’t a role where design hands off to engineering. You’ll own the full arc from visual concept to shipped product.
You’ll be a key contributor to Rillet’s platform refresh—evolving our design language, building out our design system, and translating brand direction into a cohesive product experience. You’ll work closely with our product designer and engineering team, and you’ll be trusted to make independent design decisions.
The best person for this role has unusually high taste and unusually high curiosity. You care about the web as a medium. You study products, interfaces, motion, tools, and patterns because you cannot help yourself. You are excited by the possibility that financial software can feel fast, elegant, precise, and alive.
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
Drive Rillet’s platform refresh across core surfaces like the launchpad, side nav, login, navigation patterns, empty states, tables, workflows, and other high-frequency product experiences.
Turn rough ideas into shipped product. You may start from a loose Figma exploration, a customer problem, a brand direction, or a half-formed product intuition—and bring it all the way to polished, production-ready UI.
Build and evolve Rillet’s design system: tokens, components, interaction patterns, motion principles, layout primitives, documentation, and the implementation details that make product-wide changes fast and reliable.
Translate our upcoming brand refresh into the product quickly and thoughtfully, making sure the platform feels cohesive rather than “reskinned.”
Raise the bar for product quality across visual design, interaction design, accessibility, responsiveness, performance, and micro-details.
Prototype in code when Figma is too slow or too static, especially for motion, interaction, responsiveness, keyboard behavior, AI workflows, and complex financial surfaces.
Identify design-to-code workflows that should be automated, systematized, or agentized. Help build the context, components, and patterns that make AI-assisted product development faster and more brand-consistent.
Partner with product designers, engineers, and founders to shape the experience—not just implement it. You’ll be expected to bring opinions, taste, and alternatives.
Notice what’s off before anyone asks. Then fix it.
Who We're Looking For
Exceptional taste. You can tell when something is almost right but not quite—and you know how to make it better.
Deep curiosity. You are constantly exploring new products, tools, interaction patterns, AI workflows, visual systems, and ways of building on the web.
You genuinely enjoy both design and engineering, and you do not see them as separate phases of the work.
Strong product instincts. You can reason from customer needs to interface decisions, not just from mockups to implementation.
Frontend fluency. You understand how modern web interfaces are built and can write clean, performant production code. React experience is preferred; Svelte is a bonus.
Comfort working from ambiguity. You do not need every requirement spelled out. You can take an open-ended product area, form a point of view, prototype options, get feedback, and ship.
Systems thinking. You care about reusable primitives, scalable patterns, design tokens, component APIs, and the difference between a one-off fix and a foundation.
High craft in the details: spacing, type, hierarchy, motion, affordances, loading states, empty states, keyboard behavior, accessibility, and performance.
A portfolio or body of work that shows strong visual judgment, interaction sensibility, and the ability to move between design exploration and production execution.
Comfort using AI tools to move faster, prototype more broadly, and automate repetitive parts of the design-engineering workflow—without outsourcing taste.
A bias toward shipping. You can move quickly without lowering the bar.
The expected base salary range for this role is $170,000–$240,000 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.
