Senior Web Developer I

Relay, Toronto, ON

The role

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 will do

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

Why Relay Might Be the Perfect Fit For You

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