  • AI-Assisted Development: Experience leveraging Generative AI tools (e.g., Claude, GitHub Copilot) to accelerate development and improve code quality.
  • Communication: Exceptional ability to translate technical architecture into business value for non-technical stakeholders and product partners.
What we offer
  • Global collaboration at scale: Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.
  • Technology with real-world impact: Build and operate modern systems at global scale, supporting 6+ millions of customers and complex supply chain operations.
  • Technical/Product/Design leadership: Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.

You will contribute to a high-impact, cross-functional project focusing exclusively on menu personalization, acting as the bridge between sophisticated recommendation algorithms and the millions of customers who use HelloFresh daily.

In this capacity, you will provide expert services to design, implement, and improve the robust microservices that serve personalized culinary options across our global markets.
