HelloFresh’s mission is to change the way people eat, forever. We’re the world’s leading mealkit provider, and our eight brands serve millions of households with meal kits, ready-to-eat meals, meat and seafood, and pet food.

About the Role: What’s in the Box

Join the Shopping AI & Search squad in our Warsaw office, part of the Shopping Journey tribe. You’ll build AI Assistant experiences on iOS and Android, including conversational search, personalized recommendations, and in-app assistant features, to help customers find and order what they love.

What You’ll Do: The Recipe

  • Build and evolve a high-scale React Native app that serves AI-powered shopping experiences across our brands.
  • Integrate LLM-powered features on the device, designing for latency, cost, non-determinism, and graceful degradation.
  • Own features end to end, from RFC to rollout, using feature flags, analytics, and A/B tests.
  • Work with GraphQL (Apollo Federation) APIs and own app reliability and performance.
  • Help shape mobile architecture across the tribe and lead medium-to-large technical initiatives.

What You’ll Bring: The Ingredients

  • Strong React and TypeScript experience, ideally with React Native. Experienced React web engineers are welcome to apply.
  • Daily hands-on use of AI-assisted coding tools (such as Claude Code, Cursor, or Copilot) and interest in production GenAI features.
  • A track record of shipping consumer apps at scale, with solid knowledge of state management, navigation, and performance.
  • Ownership of code quality, including unit, integration, and E2E testing, code review, and pre-release checks.
  • Strong collaboration skills across backend, AI, product, and design teams.

Nice to Have

  • LLM integration in production, native iOS (Swift) or Android (Kotlin) experience, multi-market feature flags, A/B testing tools, and search or recommendation systems.

What We Offer: The Toppings

  • Collaboration with HelloTech’s international engineering teams and a strong knowledge-sharing culture.
  • Real impact: AI systems that serve millions of customers worldwide.
  • Technical leadership and end-to-end ownership in an autonomous, product-led setup.
  • Modern workspace at Mennica Legacy Tower (Prosta 20), with showers, breakout zones, outdoor space, bike parking, and refreshments.

Are you the missing ingredient? If you don’t tick every box but think you’d thrive here, we’d still like to hear from you. We aim to review your profile and respond within 5 business days.
