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.

Web Development builds and runs relayfi.com — the pages, components, content platform, and infrastructure that turn organic search, AI-driven discovery, and paid traffic into new Relay accounts. We're a small team with a big impact, moving fast while holding a high bar for performance, accessibility, and SEO.

We're looking for a Senior Web Developer to 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.

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. Your technical judgment will carry weight here, and you'll have the autonomy to challenge assumptions, influence priorities, and shape how we build.

What You’ll Be Doing

- Project Ownership: Lead complex,



multi-part projects end-to-end — define scope, set milestones, coordinate with cross-functional teams, and deliver high-quality work on time. Own what happens after launch by measuring performance, identifying opportunities, and iterating on improvements

- Technical Architecture: Define the technical approach for features and projects, making thoughtful decisions around server/client boundaries, caching, revalidation, and CDN behaviour. Balance performance, scalability, and technical debt while proactively simplifying systems, improving maintainability, and addressing root causes

- Performance, Accessibility & Technical SEO: Proactively improve site performance, accessibility, security, and technical SEO, including structured data, metadata, and semantic markup that improve discoverability across search engines and AI platforms

- Content Platform Development: Build and optimize integrations between the headless CMS and front end, developing scalable content models and tools that empower non-technical teams to manage and publish content independently

- AI-Driven Development: Build and integrate AI workflows and agents that improve development efficiency, from automated code reviews and performance monitoring to design-to-component generation. Establish testing and review guardrails to maintain quality and help the team adopt AI effectively





- Measurement & Experimentation: Build and maintain analytics, event tracking, attribution, feature flags, and A/B testing infrastructure to support conversion optimization. Own integrations between the website, marketing tools, and CRM systems, including forms and lead routing

- Code Quality & Testing: Set a high bar for maintainable, performant, and well-documented code. Define testing strategies across unit, integration, and end-to-end tests, ensuring quality and reliability are built into every project

- Cross-Functional Leadership & Mentorship: Serve as a trusted technical partner to Marketing, Design, Product, and external agencies, translating business needs into technical solutions and driving alignment on priorities and tradeoffs. Mentor developers through pairing, code reviews, and knowledge sharing, while helping cross-functional partners navigate technical decisions
