Senior eCommerce Engineer

M/F/D | Munich, Zagreb, Trnava | Remote

We offer

  • No bullshit work environment
  • Real technical ownership — shops that make money while you work on them
  • Personal impact
  • Career option as Lead Dev / CTO in one of our ventures
  • Awesome colleagues
  • True home office

Commerce stack

  • Shopify, ideally Plus — themes, apps, checkout extensibility
  • Headless commerce where it earns its keep
  • Payment, tax and shipping configuration across several countries
  • Migrations under live traffic — no downtime, no lost rankings
  • Two journeys in one funnel — repair and replace, laid side by side, so the shop knows when a repair should become a new device

Frontend stack

  • 100% TypeScript
  • React
  • AstroJS
  • Tailwind / Shadcn
  • Core Web Vitals as a hard requirement, not a report

Integrations & data

  • Order relay into ERP and fulfillment backends
  • Product, price and stock feeds — in and out
  • Analytics wiring that survives a replatform: GA4, GTM, server-side events
  • SEO mechanics: redirects, canonicals, structured data
  • Journey and decision data — what a customer looked at, what they were quoted, what they chose

Engineering philosophy

  • Pragmatic, not dogmatic
  • Migration and redesign are two projects, never one sprint
  • Every checkout change is measured, or it didn't happen
  • Principle of least surprise
  • Build the rollback before you need it
  • Two journeys, one decision — the funnel earns trust by getting the repair-or-replace call right

Requirements

  • You've taken a shop live — or migrated one — while it was making money
  • You tell us unprompted what went wrong last time
  • You think in checkout probability, not in design taste
  • Technology-agnostic mindset
  • Fluent communication in English
