Senior Frontend Software Engineer

What you will do

Build and evolve high‑performance frontend features on our consumer‑facing web platforms, with a strong focus on Core Web Vitals and SEO best practices that directly impact organic audience growth.
Own frontend architecture decisions within a cross‑functional team (product, design, backend devs), ensuring code quality, scalability, and measurable performance improvements.
Drive technical SEO initiatives, from rendering strategy and structured data to crawlability and page speed, collaborating closely with SEO and product stakeholders.
Explore and develop new content and engagement channels aimed at deepening user engagement with our platforms.
Analyse frontend performance using real‑user metrics and synthetic tooling, identifying bottlenecks and leading the resolution with a data‑driven approach.
Mentor junior and mid‑level engineers, fostering a culture of quality, ownership, and continuous improvement.
Integrate AI‑assisted development practices (e.g. Claude Code) into day‑to‑day workflows and contribute to AI‑powered product features that shape how millions of shoppers interact with our platforms.
You’ll partner with the Engineering Manager to support healthy team dynamics and contribute to a culture where people do their best work. We expect the same collaborative growth mindset from your peers.
