The Web Engineer is the technical owner of KAST's public web presence. The role brings our marketing web stack fully in-house, migrating the site from Webflow to Next.js + Sanity and owning it long-term โ€” architecture, build, integrations, SEO, performance, and day-to-day operations.

This role is for builders, people who take initiative, think in systems, and care deeply about doing great work. If youโ€™re excited about working at the intersection of technology, execution, and impact, youโ€™ll feel right at home at KAST.

What Youโ€™ll Be Doing

  • Build and own the new Next.js + Sanity site, including a template system that lets Marketing and Content publish without dev support.
  • Lead the Webflow โ†’ Sanity migration without breaking URLs, SEO equity, or analytics.
  • Ship campaign and product landing pages from Figma to production โ€” build, QA, deploy, monitor.
  • Operate the web infrastructure: DNS, SSL, redirects, Cloudflare, and edge Workers.
  • Integrate the site with third-party systems (FX/currency API, lead capture, Pinpoint ATS, CRM, analytics).
  • Own SEO, Core Web Vitals, accessibility (WCAG AA), and analytics.
  • Run the website intake queue and keep stakeholders aligned across time zones.
  • Own reliability: uptime, monitoring, and launch-day fixes.

What You'll Bring

  • Strong production experience with Next.js / React.
  • Hands-on with a headless CMS, Sanity strongly preferred (schemas, editor experience, publishing).
  • Track record migrating marketing sites without losing SEO, URLs, or analytics.
  • Solid web infrastructure skills: DNS, SSL, redirects, CDN, Cloudflare, edge Workers.
  • Ability to build lightweight back-end integrations (route handlers, serverless functions, webhooks).
  • Strong technical SEO, performance, and accessibility (WCAG AA) knowledge.
  • Self-directed operator who can own a site solo and ship fast across distributed time zones.

Nice to have

  • Experience in fintech, crypto, or stablecoin/neobank products.
