What you'll do

  • Build internal products end-to-end, from the Slack ping through root-cause analysis in production data to the fix going live shortly after
  • Turn fuzzy requirements from influencer marketing, e-commerce, finance and customer care into the right feature; prioritize, scope and cut
  • Use Cursor, agents and LLM features as standard tools to ship fast without losing sight of quality
  • Connect Shopify Admin API, payment and affiliate systems (e.g. GoAffPro), Resend and analytics sources to internal databases
  • Further develop the Shopify storefronts for DE and NL
  • Own monitoring, clean migrations and fail-closed behavior for permissions and shipping, since real users, emails and revenue depend on production

What we're looking for

  • Several years of experience in software development
  • Ideally TypeScript, React/Next.js, Postgres (Supabase) and Vercel
  • Demonstrably ships faster thanks to AI-assisted development; masters agents, prompting and review discipline
  • Has worked as Product Owner, founder or in a hybrid role and recognizes what is really behind a request
  • Knows terms like CM3, attribution, draft order or conversion, or builds this knowledge in the first four weeks
  • Works independently: without a ticket system and without a second dev team as a safety net
  • Fluent German and solid English
