Senior Mobile Product Engineer, Menu Discovery

Location: Warszawa, Masovian Voivodeship, Poland

Department: Tech

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

HelloFresh’s Menu Discovery squad owns the customer experience that helps millions of people find and customise meals across brands and markets. The squad is compact and cross-functional, and what customers do in the app shapes every decision we make. The work runs on our React Native apps for iOS and Android, which turn federated GraphQL responses into fast, reliable shopping experiences. Performance is a requirement from day one, and we design for it from the first RFC. You’ll take features from RFC to production, rolling them out gradually across markets with feature flags and measuring impact through analytics events and A/B tests. Beyond the squad, you’ll help shape architecture across the tribe, from navigation and state management to module boundaries. If you want a large technical surface area and a visible impact on a large customer base, this role offers both.

What you’ll do: The Recipe

• Lead the app experience, owning the metrics that reflect quality for mobile customers (retention, crash-free sessions, conversion).
• Work beyond your specialization when the problem demands it. Your specialization anchors your work without limiting it.
• Operate what you build. You instrument, monitor, and improve your systems in production. Shipping starts the learning cycle.

What you’ll bring: The Ingredients 

• Hands-on experience working with AI tooling (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.
• Deep expertise in React Native and TypeScript. Proven ability to design, build, and operate high-traffic consumer mobile apps used by millions, with a clear understanding of the impact on software architecture, dependencies, and business value.
• Deep mobile engineering expertise, with experience across the app release cycle, test automation, on-device performance and platform UX conventions.
• You take full ownership. You have a bias to ship. You finish the last twenty percent.
• You have product sense and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.

Above all, we are looking for individuals 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.

What we offer: The Toppings

• Global collaboration at scale: Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.
• Technology with real-world impact: Build and operate modern systems at global scale, supporting 6+ millions of customers and complex supply chain operations.
• Technical/Product/Design leadership: Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.
• End-to-end development/delivery: Drive decisions from problem definition to production, improving systems and enabling long-term scalability.
• Access to workspace at Warsaw Centre Point. The hub offers modern facilities including showers, breakout zones, outdoor space, cycle parking, and refreshments (coffee, soft drinks, and fruit).
