React Native Engineer, Consumer Alliance

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. HelloTech works in autonomous, cross-functional alliances, each owning a specific product or domain end-to-end. By working with our Warsaw office, you will help shape scalable, data-driven products used across our markets, working with a modern tech stack and international teams to continuously improve how people discover, order, and enjoy HelloFresh’s products, today and in the future. About the role: What's in the Box How do we transform a customer into an engaged user? In the Loyalty & Virality Tribe , we own the relationship. We are the architects of the HelloFresh Rewards and Loyalty ecosystem, where our goal is to create a "sticky" experience that delights our members and keeps them coming back. You’ll be contributing to a high-cadence team focused on one primary goal: Loyalty Member ROI . The team doesn't just build features; it builds reasons for millions of users to engage with their reward points, explore new products, and feel valued at every step of their journey—from the shopping funnel and beyond. What you’ll do: The Recipe Drive Loyalty ROI: Design and ship features across the Loyalty and Rewards domain that encourage members to earn, track, and—most importantly—spend their points.

High-Velocity Iteration: We move fast. You will help us maintain an aggressive development cadence, turning hypotheses into live experiments in day(s), not weeks. Shape the Backlog: You are encouraged to contribute to our hypothesis backlog, helping decide what is built based on data coming from customer behavior. What you’ll bring: The Ingredients Agentic Engineering : Meaningful experience using AI coding agents (e.g., Claude Code, Cursor, Copilot) as part of your regular workflow. You use AI agents as thought partners to onboard on unfamiliar codebases and navigate new areas of the code. You are developing a feel for how the way you frame tasks for AI tools affects the quality of results, and for where AI assistance needs closer supervision. You are curious about how and why AI tools fail and are building habits around verification. Mobile Experience: A minimum of 1-2 years of hands-on experience with React Native and a minimum of 3 years of overall experience in mobile development or web-engineering. Component-Based Architecture: Solid working experience in building component-based architectures using React.js, coupled with a deep understanding of integrating frontend and backend services seamlessly. "Full-Stack Ready" Mindset: You aren't afraid of the "black box" of the backend. You’re willing to jump into APIs and services to unblock yourself and the team. Development Process Excellence: Familiarity with CI/CD workflows, along with solid testing practices, including unit, integration, and end-to-end testing. Collaboration: Strong collaboration skills when partnering with product designers to deliver impactful user experiences. The Speed Factor: You thrive in environments with aggressive prioritization, demonstrating an ability to mak
