About the Role

Senior Frontend Engineer – Contract (3 months, with possibility to extend)

Responsibilities

• Lead front‑end build/migration of pages and components from Stencil to Catalyst (or a headless alternative) using the architecture defined by our SI vendor.
• Implement a high‑performance front‑end layer: ensure site speed, Lighthouse metrics, core web vitals improvements.
• Collaborate with Product, Design, and Engineering leadership to integrate smoothly with backend APIs and MakeSWIFT configuration.
• Build reusable component libraries, UI patterns, and page templates aligned to our design system and brand.
• Work in an Agile/Scrum environment; deliver sprints of new pages/features, monitor and fix performance regressions.
• Provide mentoring and knowledge transfer to new full‑stack engineers to ramp them up on the Catalyst/Makeswift environment.
• Help define monitoring and instrumentation for front‑end performance (e.g., real‑user metrics, analytics hooks) and support integration with backend performance analytics.

Requirements

• Strong front‑end engineering background (6‑10 years) in React, TypeScript, modern CSS/Sass, responsive design, and performance optimisation.
• Proven experience in a headless e‑commerce or large CMS architecture, ideally with migration from monolithic or older front‑end frameworks such as Stencil to a headless/API‑first approach.
• Experience with BigCommerce Catalyst (or similar headless BigCommerce) or other headless CMS frameworks (e.g., Contentful, Shopify Hydrogen, Next.js) is a significant plus.
• Demonstrated record of improving web performance (Core Web Vitals, Lighthouse scores, page‑load times, TTI, etc.).
• Comfortable collaborating in multi‑vendor, large‑team environments; able to pick up existing codebases quickly and lead builds with limited ramp‑up.
• Excellent problem‑solving, clear communication, and ability to mentor others.
• Familiarity with CI/CD pipelines, front‑end performance tooling (WebPageTest, Lighthouse CI, etc.), browser profiling, and bundler optimisation.
• Bonus: experience in e‑commerce (luxury/retail) environments, understanding of the BigCommerce ecosystem, and Stencil limitations.

Desirable Attributes

• Self‑starter, comfortable with ambiguity (legacy Stencil context, integration issues).
• Pragmatic trade‑off mindset (speed vs. perfection) given urgency.
• Able to document and articulate decisions, supporting hand‑over to internal teams.
• Experience in international/EMEA deployments helpful as you’ll be working globally.
