Job OverviewAs a Senior Frontend Developer, you will play a critical role in enhancing Mejuri's digital experience, ensuring our website and customer-facing applications reflect our commitment to excellence. You'll work on high-impact projects, collaborate closely with cross-functional teams, and help shape the future of our digital presence, including how we use AI to build faster and better.
What you'll do- Build and maintain performant, scalable web applications on Shopify and Hydrogen, with a focus on performance, accessibility, and SEO.
- Lead architectural decisions for frontend projects and refactor existing systems, raising code quality as you go.
- Use AI coding tools as part of your daily workflow, with the judgement to know when to lean on them and when not to.
- Build AI-assisted workflows and internal tooling that make the wider team faster, not just yourself.
- Contribute to customer-facing AI features (search, personalization, content generation) and help evaluate whether the output is good enough to ship.
- Partner with design, product, and backend to turn ideas into seamless customer experiences.
- Mentor junior and intermediate developers, and contribute to code reviews, planning, and retrospectives
What you'll bring to the team- 5+ years of frontend development experience with strong TypeScript/JavaScript expertise
- Deep React experience, including React Router v7 or equivalent modern routing frameworks
- Experience building and maintaining large-scale e-commerce applications
- Strong understanding of Shopify's ecosystem, particularly the Hydrogen framework
- Experience with headless commerce architectures
- Hands-on experience with AI coding assistants in a production codebase, and a clear point of view on where they help and where they create risk
- Comfort writing effective prompts and context for AI tools, and reviewing AI-generated code with the same rigour you'd apply to a colleague's PR
- Proficiency writing unit and integration tests
- Experience with GraphQL and REST APIs
- Experience with performance optimization and web vitals
- Strong UX/UI sensibilities and the ability to collaborate closely with design
- We're building an AI-fluent organization. We welcome candidates at all stages of their AI journey - what matters is curiosity, a willingness to learn, and an openness to working alongside AI tools as part of how we do our best work.
Things we consider an asset: - React Native or mobile experience. This role sits on web, but engineers who can move across both are a real advantage to us.
- Exposure to agentic tooling or MCP-based integrations
- Experience shipping an AI-powered product feature end to end
- Familiarity with observability tooling (Honeycomb, Sentry, or similar)
- Experience with modern frontend tooling at scale (Git, NPM/Yarn, SCSS, ES6)
