The opportunity

The Growth Mega Alliance (GMA) builds the platforms that power how HelloFresh acquires, converts, and retains customers across 18 markets and multiple brands, across five pillars: AdTech, Conversions, Payments, Communications, and Customer Value Optimization (CVO).

What you'll do

  • Own GMA's GenAI strategy: identify the highest-leverage opportunities across all five pillars where AI/ML unlocks step-change outcomes, for both engineering productivity and customer-facing capabilities.

  • Establish agentic development workflows: where specs drive AI-assisted code generation — and scale them from early adopters to standard practice. Build the guardrails and reference architectures that enable squads to work AI-natively.

  • Develop and articulate a clear point of view on how engineering teams need to: evolve in skills, process, and culture to realize the gains that agentic tools make possible.

  • Own the long-term technical architecture across GMA's five pillars: real-time personalization, experimentation at scale, AI/ML-driven automation, and cross-pillar data integrity.

  • Lead the most complex architectural decisions (shared identity schemas,: experiment assignment, AdTech-to-Conversions signal loops, payment authorization flows) and drive migrations with large impact.

  • Ensure GMA platforms integrate cleanly with internal infrastructure and meet: reliability, latency, and observability requirements at a global scale.

What they're looking for

  • Define GMA's experimentation strategy and execution framework to optimize: experimentation-based decision-making at scale.
  • Own the data path from customer event to business decision: instrumentation standards, identity resolution, attribution windows, and signal quality.
  • Define GMA's multi-year technical vision and communicate it with the: precision engineers need and the clarity executives can act on. Represent GMA in company-wide programs.
  • Partner with Intelligent Platforms, Consumer, and Operations Mega Alliances: to drive shared architectural standards and prevent fragmentation.
