Senior Mobile Engineer - React Native, Platform/Infrastructure (all genders)

Work with HelloFresh in Warsaw and its HelloTech organisation, HelloFresh’s global technology backbone with more than 1000 people, building the digital products that power our end-to-end food experience. From meal kits and ready-to-eat meals to specialty offerings like pet food and premium meat & seafood, HelloTech creates the platforms that bring tailored food solutions to millions of customers every month. Our subscription-based, direct-to-consumer model relies on technology at every step, from customer-facing apps and personalization logic to pricing, forecasting, supply chain optimization, and initiatives that help reduce food waste. While our brands operate independently to serve distinct customer needs, they are united by shared platforms, data, and operational excellence built by HelloTech.

About the role: What's in the Box

As a Senior Mobile Engineer in the Consumer Foundations tribe, you'll join the Client Platform squad and work hands-on to help evolve our mobile platform. Alongside engineering and product teammates, you'll help move our white-labeled, multi-brand application from a native brownfield React Native setup toward a more scalable greenfield architecture. This is a chance to build strong technical foundations, contribute to shared tooling, and help a growing engineering organization ship reliable mobile software.

Our stack: Core: React Native, iOS (Swift), Android (Kotlin) Architecture: Monorepos, White-labeling, shared npm packages CI/CD & Automation: Bitrise, Expo (Future) Observability & Testing: Honeycomb, Maestro E2E

What you’ll do: The Recipe

At HelloFresh we are moving away from a model where software developers just execute tickets toward one where product engineers are trusted to own customer problems. A Product Engineer takes a problem, forms a point of view, validates it with customers and data, and ships it using AI as a force multiplier.
