About the role

The Growth Alliance enables HelloFresh to expand by getting more customers to try, recommend, and return to our products. We build digital experiences used by customers around the world, including our checkout funnel, discounting and wallet services, experimentation platforms, and referral technology. If you’re excited about building customer-facing products at global scale—and shaping how millions of people interact with food and technology—this is a strong place to grow your impact. S'more about the team As a Senior Mobile Developer, you’ll join a cross-functional team building features that empower both customers and internal stakeholders. You’ll contribute to developing high-quality mobile and web experiences using modern technologies, with a focus on performance, accessibility, and maintainability. You’ll work closely with senior engineers while taking ownership of well-defined features end-to-end, growing your technical depth and product intuition over time. We’re also increasingly leveraging AI-driven tools and systems —from developer productivity (e.g., code generation, testing support) to customer-facing experimentation and personalization—so you’ll have opportunities to build and iterate in an evolving, AI-enabled environment. Lettuce share what this role will be responsible for • Collaborate within a cross-functional team of engineers, product managers, designers, and analysts • Build, test, and ship features that improve the customer experience and drive growth • Contribute to code quality, performance, and maintainability of our mobile applications • Participate in system design discussions and help implement scalable solutions • Work with backend services and APIs to deliver seamless end-to-end functionality • Use data and experimentation to inform product decisions and iterate on features • Contribute to a culture of continuous improvement through code reviews and team discussions • Stay current with emerging tools and practices, including AI-assisted development workflows • Work beyond your specialization when the problem demands it. Your specialization is your anchor, not your boundary. • Operate what you build. You instrument, monitor, and improve your systems in production. Shipping is the beginning of the learning cycle, not the end. • All other duties, as assigned Sound a-peeling? Here's what we're looking for • 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. • 1–2 years of experience working with React or React Native • 2–4 years of experience building mobile applications (iOS and/or Android) using technologies such as Swift, Kotlin, or React Native • Solid understanding of integrating frontend applications with backend services and APIs • Experience with testing (unit, integration, or end-to-end) and CI/CD pipelines • Familiarity with agile development and working in cross-functional teams • Ability to collaborate effectively with designers and product managers • Strong problem-solving skills and a willingness to learn and grow • Nice to have: Experience with experimentation platforms (A/B testing) • Nice to have: Exposure to AI/ML-powered features or tools (e.g., personalization, recommendations, or developer tooling) • Nice to have: Experience optimizing performance for mobile applications at scale • 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. Let’s cut to the cheese
