Senior Frontend Engineer

What We Do

Rillet serves 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 Windsurf, Postscript, and Finch 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 We Need:

We're looking for an experienced frontend engineer to shape the user experience of Rillet's industry-defining accounting and finance software. You'll join a growing engineering team and work closely with the CTO, product, and design to build intuitive, high-performance interfaces that finance professionals love to use. This is a remote-first role with the option to work from one of our office hubs in New York City, San Francisco, or Barcelona.

While we offer flexible work arrangements, we have a preference for people excited about helping us build our presence in San Francisco Bay Area or New York City as we grow, whether that's through occasional office time, team gatherings, or local hiring efforts.

What You'll Do:

• Lead technical decisions for frontend architecture, driving discussions around component design, state management, and performance optimization

• Partner with product managers, designers, and finance experts to influence product direction, advocating for user experience and balancing design vision with technical feasibility

• Drive customer research initiatives, translating user feedback into frontend requirements and championing accessibility and usability in engineering decisions

• Establish and champion continuous delivery practices for frontend deployments, mentoring team members on deployment strategies and ensuring reliable, frequent releases

• Lead by example in test-driven development and automation, building robust testing frameworks for UI components and fostering a quality-first culture

• Own frontend performance and user experience excellence, implementing monitoring solutions, optimizing bundle sizes and load times, and ensuring exceptional interface responsiveness

• Mentor frontend engineers on the team, conducting code reviews, and raising the technical bar across the organization

What We're Looking For:

• 5+ years of frontend engineering experience with a Bachelor's degree in Computer Science, including a proven track record leading large-scale frontend projects and architecting component systems

• Strong proficiency in TypeScript and modern frontend frameworks

• Expertise in responsive design, CSS architecture (CSS-in-JS, Tailwind, CSS Modules), cross-browser compatibility, and frontend performance optimization

• Strong understanding of accessibility standards (WCAG), modern web APIs, and experience working with RESTful APIs or GraphQL

• Ability to find practical solutions to real user problems while thriving both independently and collaboratively within a small team, with a passion for continuous learning and knowledge sharing

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.

• 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.
