Senior Front End Engineer

Since 2015, Mejuri has reimagined what fine jewelry can be in a modern world—shifting it from a traditional gift to to a personal choice rooted in self-expression.

Founded by third-generation jeweller Noura Sakkijha, the brand was built on a simple idea: fine jewelry shouldn’t require a special occasion, and it should never come with guilt. It’s about celebrating yourself—your style, your life, your everyday.

Mejuri meets customers where they are—online, in app, and through a growing global retail footprint of 58+ stores worldwide. Mejuri is also deeply committed to doing things the right way, with responsible sourcing, sustainable practices, and philanthropic initiatives that reflect our values and long-term vision.

Job Overview As 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

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)
