Senior Web Developer

Join Relay, a high-growth fintech company, as a Senior Web Developer. In this role, you'll lead complex web projects, shape technical decisions, and help scale the platform behind Relay's growth. You'll work in a modern Next.js codebase with React, TypeScript, Tailwind, and Contentful, tackling architectural challenges that directly impact site performance, scalability, and discoverability. You'll own projects from technical planning through launch, mentor other developers, and partner closely with teams across the company.

Lead complex web projects from technical planning through launch, ensuring high-quality work and measuring performance post-launch.

This is an ideal role for a front-end developer who thrives on ownership, enjoys solving complex technical problems, and wants to make a measurable impact

About Relay

You push relentlessly for reinvention: You're always asking "how can this be better?" -- in your work, in your craft, in yourself. Comfort is a signal to push harder, not coast. You'd rather build something better than defend something familiar

Small businesses are why we're here: Relay exists to help them thrive -- and that mission has to resonate with you

You build with AI, not just use it: You're actively embedding AI into how you work, pushing what's possible, and bringing your team along with you

We're looking for people who are relentless, curious, and care deeply about the work. You're encouraged to apply even if your experience doesn't perfectly match the job description -- your perspective and drive matter more

Responsibilities

• Define the technical approach for features and projects, making thoughtful decisions around server/client boundaries, caching, revalidation, and CDN behavior.
• Proactively improve site performance, accessibility, security, and technical SEO, including structured data, metadata, and semantic markup.
• You actively use AI tools and workflows to improve development efficiency, with the judgment to evaluate outputs, manage risks, and maintain code quality
• You're a proactive problem-solver who thinks beyond individual tasks, understands customer needs, challenges assumptions, anticipates downstream impacts, and adapts quickly to new technologies and feedback

Requirements

• You're skilled in modern front-end architecture, with a strong understanding of server/client boundaries, caching, revalidation, and CDN behaviour. You think in systems, designing scalable solutions while anticipating downstream impacts
• You have 4+ years of front-end development experience, ideally in a high-growth B2B SaaS or fintech environment, with a proven ability to work independently and deliver high-quality solutions
• You have a strong understanding of web performance, accessibility, and technical SEO, including Core Web Vitals (LCP and CLS), image optimization, bundle analysis, WCAG 2.1 AA, semantic HTML, metadata, structured data, sitemaps, and heading hierarchy
• You're strong in React, Next.js, and Node, and you write TypeScript by default. Our repo is fully typed in strict mode with type checking enforced in CI, so strong TypeScript proficiency is essential
• You're proficient in Tailwind and experienced working with design systems, reusable components, and headless CMS platforms. You understand content modelling and integrations, with experience in Contentful and GraphQL being valuable but not required
• You have strong project management and communication skills, with the ability to lead cross-functional initiatives, manage competing priorities, and translate technical concepts for non-technical stakeholders
• You've built analytics, experimentation, and marketing integrations using tools like Segment, GTM, Statsig, and HubSpot
• You've worked with AWS Amplify Hosting or similar CI/CD platforms and built end-to-end tests using Playwright or equivalent tools
• You've built animations using GSAP or Framer Motion and have experience with SCSS
• You seek out feedback: You see directness as respect, not criticism. You actively seek input, sit with hard truths, and use feedback as fuel for improvement
• You crave autonomy: We trust our team with big challenges and the freedom to solve them. If you’re someone who takes initiative, is comfortable taking risks, and seeks input when needed, you’ll find the freedom here empowering
• You own your work: You take pride in your work, follow through on commitments, and feel a deep sense of responsibility for outcomes, not just tasks
• You’re energized by complexity and ambiguity: You enjoy tackling problems that don’t come with a playbook. You’re comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward
• You care about impact, not noise: You care deeply about the substance of your work. You measure success by results, not recognition, and you let your work speak for itself
