At HelloFresh we are moving away from a model where software developers just execute tickets toward one where product engineers are trusted to own customer problems. A Product Engineer takes a problem, forms a point of view, validates it with customers and data, and ships it using AI as a force multiplier.Build and maintain personalized landing pages and funnel steps using React, TypeScript and Next.JsWork across frontend and infra tasks, including Cloudflare Workers, cache rules and Vercel Edge functionsIntegrate dynamic content and variations coming from our CMSImplement and validate A/B tests with Statsig, ensuring clean tracking and test integrityEnsure strong performance on mobile and desktop, focusing on Core Web Vitals and low latency personalizationImplement and monitor frontend performance and error tracing using tools like Sentry and HoneycombWork with SSR and modern rendering patterns in Next.Js to balance performance, caching and personalizationUse AI tools to speed up development, UI building and content workflowsWork closely with product, machine learning and design teams to shape new personalized experiencesOwn features end to end, from design to rollout, monitoring and iterationWork 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.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.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.Solid experience with React, TypeScript and modern frontend development, including strong debugging skills across frontend and infra logicHands on experience with Next.Js and edge runtimes like Vercel Edge or Cloudflare WorkersGood understanding of caching strategies and how they affect personalization and performanceExperience with web performance and frontend monitoring, including Core Web Vitals, Sentry, Honeycomb or similar toolsExperience writing and maintaining tests at different levels, including unit, integration and end to endExperience integrating with a CMS, for example Contentful or Builder.IoExperience with A/B testing frameworks (e.G. statsig, optimizely)Familiarity with analytics platforms like GA4 or SnowplowYou take full ownership.
