<p>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.</p> <p>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.</p> <p>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.</p> <h2><strong>About the role: What's in the Box</strong></h2> <p data-path-to-node="1">Our mission is pricing and plans that flex with the customer, not against them.<span class=""> The squad directly impacts revenue across web,</span> iOS, and Android—owning the surfaces our global brands depend on: weekly menu pricing, plan building, bundles, and the cancellation flow. When pricing logic or an experiment misbehaves across markets, we find and fix it.</p> <p data-path-to-node="2">Our React Native codebase is shared across the engineering organization, with our squad owning the pricing and plan surfaces and the underlying backend services. Sitting inside the Consumer Mega Alliance, we build scalable logic across multiple brands (HelloFresh, EveryPlate, GreenChef, Factor, and more), currencies, and pricing models.</p> <p data-path-to-node="3">This is a mobile-first, senior role: most of your time will be spent in our shared React Native codebase shipping to iOS and Android. We are an AI-first engineering team looking for a senior engineer who can own problems end to end, elevate our mobile architecture, and set the standard for testing and observability.</p> <p>At HelloTech, flexibility and cross-functional collaboration are core to how we work. While this role is aligned to a specific Alliance, strong candidates may also be considered for opportunities across different teams or projects.</p> <h2><strong>What you’ll do: The Recipe</strong></h2> <ul data-path-to-node="6"> <li> <p data-path-to-node="6,0,0"><strong data-path-to-node="6,0,0" data-index-in-node="0">End-to-End Ownership:</strong> Lead feature delivery from technical design and implementation to phased rollout behind feature flags and post-launch measurement.</p> </li> <li> <p data-path-to-node="6,0,0"><strong data-path-to-node="6,1,0" data-index-in-node="0">Mobile Architecture:</strong> Build and refine high-performance React Native surfaces across brands, focusing on modularity, offline resilience, and cross-market price correctness.</p> </li> <li> <p data-path-to-node="6,2,0"><strong data-path-to-node="6,2,0" data-index-in-node="0">Full-Stack Fluency:</strong> Primarily work with React Native and TypeScript, while comfortably navigating our GraphQL APIs and backend pricing data when needed.</p> </li> <li> <p data-path-to-node="6,3,0"><strong data-path-to-node="6,3,0" data-index-in-node="0">Quality & Observability:</strong> Maintain high test coverage (unit, integration, and Maestro E2E) and establish proactive observability (metrics, traces, alerts) for critical revenue paths.</p> </li> <li> <p data-path-to-node="6,4,0"><strong data-path-to-node="6,4,0" data-index-in-node="0">Mentorship & Experimentation:</strong> Run and analyze A/B experiments, unblock mid-level engineers through thoughtful reviews, and share mobile patterns across chapters.</p> </li> <li> <p data-path-to-node="6,5,0"><strong data-path-to-node="6,5,0" data-index-in-node="0">AI-First Delivery:</strong> Leverage AI tools across the entire engineering lifecycle—from scoping and design to coding and test generation—while exercising strong critical judgment on generated code.<br><br></p> </li> </ul> <h2><strong>What you’ll bring: The Ingredients </strong></h2> <ul> <li> <p data-path-to-node="9,0,0"><strong data-path-to-node="9,0,0" data-index-in-node="0">Core Experience:</strong> Senior-level software engineering experience, including 2–3+ years of production React Native alongside TypeScript and modern React.</p> </li> <li> <p data-path-to-node="9,1,0"><strong data-path-to-node="9,1,0" data-index-in-node="0">Architecture & Systems:</strong> Proven ability to manage complex state, modular architectures, and API integrations (GraphQL/REST) in large-scale shared codebases.</p> </li> <li> <p data-path-to-node="9,2,0"><strong data-path-to-node="9,2,0" data-index-in-node="0">Testing & Release Rigor:</strong> Hands-on experience with unit, integration, and E2E testing (e.g., Jest, React Native Testing Library, Maestro), paired with solid CI/CD release hygiene.</p> </li> <li> <p data-path-to-node="9,3,0"><strong data-path-to-node="9,3,0" data-index-in-node="0">AI-Assisted Workflow:</strong> Proven track record of u
