Senior Frontend Engineer, Consumer Alliance (f/m/x)

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 is a customer transformed into an engaged user? Within the Loyalty & Virality Tribe , the relationship is maintained through technical excellence. The scope involves architecting the HelloFresh Rewards and Loyalty ecosystem, where the goal is to create a "sticky" experience that keeps members engaged. This role involves collaborating with a high-cadence team focused on one primary goal: Loyalty Member ROI . The project focuses on building reasons for millions of users to engage with reward points, explore new products, and feel valued at every step of the journey—from the shopping funnel and beyond. What You’ll Do: The Recipe Drive Loyalty ROI: Design and ship features across the Rewards domain that encourage members to earn, track, and—most importantly—spend their points. Full-Stack Flexibility: While the focus is React , the service includes contributing to React Native mobile experiences and engaging with Backend topics to ensure end-to-end delivery of features. High-Velocity Iteration: Maintain an aggressive development cadence, turning hypotheses into live experiments in day(s), not weeks. AI-Augmented Engineering: Develop usage patterns and tailor processes to enable optimal customer impact. This involves finding ways to utilize AI to automate tasks and accelerate code generation. Shape the Backlog: Drive the product direction. High-level contribution to the hypothesis backlog is expected, helping decide what is built based on data coming from customer behavior. What You’ll Bring: The Ingredients Web Mastery + Mobile Curious: 5+ years of experience with React and TypeScript . You have a solid foundation in web, and either past professional experience with React Native or a hunger to apply your skills here "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. The Speed Factor: You thrive in environments with aggressive prioritization. You know when to build for the long term and when to build a "quick and dirty" experiment to prove a point. GenAI Savvy: You are already using AI tools to supercharge your workflow and are excited about pushing the boundaries of how AI can assist in product development and improving the customer experience Cross-Funnel Thinking: You understand that "Loyalty" doesn't stop at the Rewards page—it lives throughout the user experience, in the checkout, the account settings, and the homepage. Above all, we are looking for people who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences. So even if you don’t “tick all the boxes” but think you’d thrive in this role, we would really like to learn more about you. Wh
