Senior Frontend Engineer

What do we do? Paddle offers digital product companies a completely different approach to their payment infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we’re a Merchant of Record for our customers. That means we take away 100% of the pain of payment fragmentation. It’s faster, safer, cheaper, and, above all, way better. We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North and serve over 6000 software sellers in 245 territories globally. The Role: The Experience Group at Paddle is made up of several closely connected teams. Two of those, Dashboard and Developer Experience (DX), are hiring for this role. Dashboard transforms our seller-facing products into rich, seamless experiences that help thousands of customers run and grow their business on Paddle, and shapes our design system to drive consistency and adoption across multiple products. Developer Experience makes Paddle a world-class platform to integrate with, owning our docs platform at developer.paddle.com http://developer.paddle.com, our SDKs and public libraries, and the tooling that makes integrating with Paddle simple and enjoyable. As a Senior Frontend Engineer in the Experience Group, you'll lead frontend craft across the products that thousands of organisations rely on, from small businesses and independent developers to the next generation of AI-native builders, whether that's the seller dashboard, our design system, or the developer-facing surfaces sellers and their engineers hit every day. TypeScript, React, and our design system are core to the work, alongside React Router 7 on the dashboard side and Astro on the docs side. You'll partner with product managers, designers, and technical writers, using our design system as a bridge between design intent and engineering reality, and you'll ensure that our UI surfaces remain consistent, accessible, and high-fidelity at scale. You'll work with experts to achieve success, develop your own skills, and grow your career. What you'll do: - Lead and help shape frontend work across the Experience Group's products, from the seller-facing dashboard, to our docs platform (built on Astro) and DX initiatives like our app marketplace, transforming them into rich, seamless experiences that help our sellers grow and our developers integrate with ease. - Own the technical direction and lifecycle of products and tooling in your remit, including public libraries like Paddle.js and our Node SDK, from technical planning through rollout and long-term maintenance. - Shape and enhance our design system in collaboration with product designers, driving adoption across multiple products as both a consumer and a contributor. - Contribute high-quality TypeScript and React code in a large codebase used by several teams, optimising for collaboration, developer experience, and throughput. - Champion frontend excellence and ways of working across the frontend guild. - Level up the team's engineering practices through mentoring other engineers, leading the technical planning of team initiatives, and driving improvements to quality with an eye for edge cases. - Collaborate on features end-to-end with product managers, designers, technical writers, and other engineers, from initial concept and planning right through to rollout, with excellent written and verbal communication. - Practise DevOps: you're responsible for getting your code to production, supporting and monitoring its performance. We'd love to hear from you if you have: - Deep proficiency in TypeScript, React, and CSS, with a track record of leading medium-to-large frontend initiatives end-to-end at scale. - Hands-on experience with design systems as both a consumer and a contributor, ideally driving adoption across multiple products. - A deep interest in excellent user experiences and how they can be achieved through technical craftsmanship. - Experience mentoring other engineers, with strong writte
