Key Responsibilities

• Design, build and ship features across our web products, from scoping to production
• Be the main engineering contact for Product and Design on your workstreams
• Build reusable components and content tooling so non-engineers can create and update pages themselves
• Keep our sites fast, accessible and SEO/GEO optimised across many languages

• Comfortable with server-side JavaScript and APIs (REST, GraphQL)
• Hands-on with Vercel, AWS or Cloudflare: deployments, CDN and caching, firewall rules, DNS, logs and monitoring
• Secure web development practices
• Fluent with AI coding tools like Claude Code, with the judgment to know when the output can’t be trusted
• Clear written and verbal English, strong presentation skills, and a self-driven work style
• BS in Computer Science or equivalent experience

Nice to Have

• Monorepos and design systems
• CI/CD and infrastructure as code
