Senior Frontend Engineer

Who We Are

Coefficient is a VC-backed SaaS startup based in the SF Bay Area. Our culture is centered around people who are smart, driven, curious and collaborative. We are embarking on a journey to unleash the power and flexibility of spreadsheets across all of the data in company systems. The founders are serial entrepreneurs whose last startup, Shopular, was backed by Y Combinator and Sequoia and acquired by Rakuten Ebates.

What We Do

Coefficient provides a no-code solution that enables business teams to access their company data in real-time directly from their spreadsheets and make it actionable across the organization. Whether their data lives in business applications, databases, data warehouses, or business intelligence solutions, business users can easily work with this data without IT involvement.

Using Coefficient, business teams can be more effective with company data that's connected, automated and performant in the most familiar and flexible analytics product - their spreadsheet. By meeting users where they are, companies can now reduce friction between IT and business teams to drive higher efficiency and growth.

Your Role

We are looking for a Senior Frontend Engineer to help us shape and deliver our vision. You will work alongside the founders to define product, design core backend architecture, and develop resilient, scalable systems from the ground up. You may be a good fit if:

• You have 7+ years of experience building and shipping production web applications


• You have deep experience with TypeScript, React, and Next.js


• You have strong fundamentals in modern frontend architecture, state management, and performance optimization


• You care deeply about UX, interaction design, and polish , especially for power users


• You have experience building complex, data-heavy interfaces (tables, dashboards, editors, workflows)


• You are comfortable collaborating closely with backend engineers and working against APIs


• You have experience deploying and operating frontend applications in production cloud environments


• You are thoughtful about software development best practices and care about code quality, maintainability, and clean abstractions


• You communicate clearly in writing and verbally; as a remote-first team, strong documentation and async communication matter


• You are self-directed, can deliver complex features with minimal oversight, and thrive in environments with high ownership and responsibility


• You are excited about joining an early engineering team and helping build both the product and the company

This is a hybrid in-office role in San Mateo, CA. We are looking for this person to be in-office three days a week with our team.

Bottom Line

This is a unique opportunity to join the early engineering team of a funded startup, and to shape the future of both our product and company. We are creating a new breed of data software that will make business teams orders of magnitude more productive when working with data.
