Senior Design Engineer

Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money—bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses. At Relay, we believe that quality and craft are no longer just nice to haves, they’re product requirements. That belief shapes how we build. Design Engineering is a small, deliberate function with a clear mandate: own the front-end across the product, hold a high bar of quality, and raise it over time. The team works directly with product and design, responsible for the UI, the interactions, and the design systems that everything is built on top of. We're expanding the team and hiring two design engineers who will have real ownership across the product. You'll work on the hardest things to get right: the details that make an interface feel intentional, the systems that make quality consistent at scale, and the problems that require someone who thinks in both design and code. This is a formative moment for the Design Engineering function at Relay while it’s still relatively new. You’ll have the chance to make an outsized role in shaping how it grows, how it integrates across product teams, and what it means for how Relay builds product going forward. If you’re curious to learn more about the standard we hold ourselves to, and the kind of work you’d be owning before you apply, check out some of our recent work: - Telegraph design system documentation https://storybook.relayfi.design/: The foundations used by engineers across the company to ship product. The details are intentional, and so is the fact we made it public. - Relay’s new home page https://relayfi.com/: a collaboration with our marketing design team to introduce a new level of expression to our front door. WHAT YOU'LL BE DOING - Set a high bar of quality across the product by owning the front-end. Identify and systematically reduce UI and UX debt, improve implementation patterns, and raise the overall level of craft across the application. - Embed within product teams to lead UI implementation for new features from concept through launch. Partner closely with product managers, designers, and engineers to ensure shipped experiences meet a high standard for quality, usability, and polish. - Own and evolve Telegraph, our design system. Define and maintain component APIs, composition patterns, interaction standards, and documentation that enable teams to build consistent, scalable interfaces efficiently. - Champion accessibility and performance as core product requirements. Ship experiences that are fast, resilient, and accessible by default through semantic implementation, keyboard support, focus management, testing, and ongoing performance optimization. - Partner closely with designers throughout the product development process. Work collaboratively in code and design tooling to iterate on concepts, refine interactions, and reduce the gap between design and implementation. Help evolve a workflow that replaces traditional handoffs with continuous collaboration. - Create leverage for the broader organization by translating intent into scalable implementation: reusable components, guidelines, sandboxes/playgrounds, and “how to use it” documentation that reduces drift. - Build the infrastructure and workflows that support AI-accelerated product development. Some areas we’re currently exploring include: automating QA and code review processes, connecting design and engineering tools, and setting up prototyping templates. WHO YOU ARE - You're well-versed in React, JavaScript (TypeScript), HTML, and modern CSS - You work in a real engineering environment. You’re comfortable using Git, writing PRs, reviewing code, and contributing directly to a shared
