Web Software Engineer (Hybrid - Tokyo)

As a Senior Web Engineer at Bitcoin.com, you design, build, and improve web products for one of the world's leading crypto content and onboarding platforms, serving millions of users globally. You take ownership of key engineering workstreams, collaborate closely with Product and Design, and leverage AI-first development practices to deliver high-quality solutions that bring crypto to the next billion users.

What you'll do

• Design, build and ship features across 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 sites fast, accessible and SEO/GEO optimised across many languages
• Own hosting and delivery: environments, CDN and caching, security rules, DNS and domains
• Support releases and lead the investigation of production issues
• Review code and raise the bar on quality, testing and documentation

What you bring

• 5 or more years of professional web development, including senior-level work on high-traffic production sites

• Hands-on experience with headless CMS platforms: content models and editor workflows that non-engineers can actually use
• Strong expertise in web performance, accessibility and technical SEO, including Core Web Vitals, rendering strategies and structured data
• Comfort with server-side JavaScript and APIs such as REST and GraphQL
• Hands-on experience with Vercel, AWS or Cloudflare for deployments, CDN and caching, firewall rules, DNS, logs and monitoring
• Knowledge of secure web development practices
• Fluency with AI coding tools like Claude Code, with the judgment to know when the output cannot be trusted
• Fluent written and verbal English, strong presentation skills, and a self-driven work style
• A degree in Computer Science or equivalent professional experience

Nice to have

• CI/CD and infrastructure as code
• Internationalisation at scale
• Automated and end-to-end testing tools such as Playwright
