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
The Client Platform squad is looking for a Senior React Native Engineer to work on the mobile and web apps as platforms. The customers are the internal feature teams who rely on such platforms to build and deliver the features that power the digital experience across all HelloFresh Group's brands and markets, used by millions of customers every day, globally.
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.
What you’ll do: The Recipe
Work on a team focused on mobile and web development, interfacing with virtually all the feature teams in the tech organization
Help to enable the feature teams to iterate fast and learn about users by planning, building, testing, and launching features
Collaborate with engineers across the department and the company to continuously improve the code base, systems, and processes
Design and develop solutions that can continue to scale
Support other team members through workshops, pair programming, and code reviews
What you’ll bring: The Ingredients
Solid hands-on experience working with AI coding agents (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents as thought partners to onboard on unfamiliar codebases and navigate new areas of the code with confidence. You have a practical sense of how the context you provide to AI tools - specifications, constraints, examples - shapes output quality, and a developing awareness of how agentic outputs can fail, with growing habits around verifying, testing, and setting boundaries on AI-generated work.
At least 2-3 years of hands-on work with React Native
A minimum of 5 years of experience working with HTML, CSS, and JavaScript
Proficiency in building component-based architectures using React.js and Node.js
Deep understanding of integrating frontend and backend services seamlessly
Familiarity with CI/CD workflows, along with solid testing practices, including unit, integration, and end-to-end testing
Strong collaboration skills when partnering with engineers and other functional roles, like product management and UX designers
Nice to have: Hands-on experience working on platform teams
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 a global scale, supporting 6+ million 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 the 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).
