Frontend Engineer

We normalize real-time telematics and execution data from hundreds of thousands of trucks and trailers — across 130+ providers — into a single API. The data is complex, the customers are technical, and the interfaces we build need to make both feel approachable. We're looking for a frontend engineer who can help us get there. This is a hands-on engineering role. You'll work closely with our founding team and product designer to ship high-quality product interfaces, contribute to our component library, and help us build the frontend foundation that scales with the company. What You'll Do Build & Ship Product Interfaces — you'll develop the data dashboards, operational workflows, onboarding flows, and developer-facing tools that our customers use every day. The work is data-heavy and technically demanding. You'll focus on turning complex, real-time logistics data into interfaces that are fast, clear, and reliable. Own the Website & CMS — you'll build and maintain Catena's marketing site and content infrastructure using Next.js and Sanity CMS. That means owning the full stack from component architecture to content modeling — ensuring the site is fast, maintainable, and easy for non-engineers to update. Contribute to Design Systems — you'll help build and maintain the component library and design patterns that keep our product consistent as it grows. You don't need to own the design system end-to-end, but you care about the craft and leave code cleaner than you found it. Optimize for Performance — our product deals with high-volume, real-time data. You'll help ensure our interfaces handle it gracefully — fast load times, efficient state management, and responsive design that doesn't degrade under pressure. Collaborate Cross-Functionally — you'll work directly with engineering, product, and design to move features from concept to production. At 15 people, that means being in the room early, asking good questions, and taking ownership of your work all the way to ship. Who Fits This Role Strong candidates are engineers who have built production-grade frontend products before and care deeply about the quality of what they ship — not just that it works, but that it's maintainable, performant, and well-structured. You're comfortable in a React/TypeScript/Next.js codebase and have opinions about how to do things well. Specifically, you: Are proficient in React, TypeScript, and Next.js and have built complex, data-rich UIs in production environments. Have hands-on experience with Sanity CMS — content modeling, schema design, and building editor experiences that non-technical teammates can actually use. Understand state management, component architecture, and frontend performance — not just theoretically, but from having debugged real problems. Have worked with APIs and know how to handle real-time or high-frequency data on the client side. Write clean, well-tested code and take code review seriously in both directions. Collaborate naturally with designers and backend engineers and can close the gap between a Figma file and a production UI. Are comfortable with ambiguity and can make good decisions when the spec isn't fully written yet. Experience with data visualization, mapping, or logistics/supply chain products is a genuine plus — but curiosity about the domain matters more than prior exposure. 3+ years of professional frontend engineering experience, with meaningful time in React, TypeScript, and Next.js production codebases. Why Catena, Why Now Catena has raised $8.25M from Shaper Capital, Floating Point, Plug and Play, Liquid 2, and leading industry angels. Customers are already using us in production — many of them are also investors. The frontend surface area at Catena is growing fast — new product capabilities, new customer-facing tools, and a design system being built from scratch. The engineer who joins now will have real ownership over how our product looks and behaves, with direct access to the people making decisions about what gets built next. Remote-first. Optional travel for team offsites and occasional on-sites. #J-18808-Ljbffr
