Job description

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)

Benefits at Mejuri

• A minimum of four weeks vacation, plus personal days and three religious/cultural observance days.
• A hybrid work model for all corporate roles
• ‘Mejuri Passport’ which allows employees who meet specific criteria to work in other locations for one month per year.
• Comprehensive medical and dental benefits, including mental health coverage, and generous personal and sick days for our full-time employees. We also offer bereavement leave, including miscarriage and stillbirth support.
• Parental leave salary top-up of up to 80%, as well as a personalized return-to-work transition and accommodation plan for full-time employees.

Please note that these benefits apply to full-time employees.
