About this role

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. About the role: What's in the Box As a Staff Mobile Product Engineer in the Consumer Foundations tribe, you will provide technical leadership for the evolution of our mobile platform. Working alongside engineering and product teams, you will help shape the core architecture, tooling, and developer experience of our mobile applications.

This is a high-visibility, high-impact opportunity to contribute to the transition of our white-labeled, multi-brand application from a native brownfield React Native setup to a highly scalable Greenfield architecture. You will combine hands-on engineering with technical leadership, helping teams adopt scalable architectural patterns, shared tooling, and engineering best practices across the mobile ecosystem. By designing automated guardrails, shared infrastructure, and scalable developer workflows, you will enable a growing team of 50+ mobile engineers to deliver high-quality software safely, independently, and efficiently.

Our stack: Core: React Native, iOS (Swift), Android (Kotlin) Architecture: Monorepos, White-labeling, shared npm packages CI/CD & Automation: Bitrise, Expo (Future) Observability & Testing: Honeycomb, Maestro E2E What you’ll do: The Recipe 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.

Shape Architectural Direction: Shape the architectural direction and contribute to the execution of our brownfield-to-greenfield React Native migration within a white-labeled, multi-brand application ecosystem. Scale Infrastructure for Growth: Design and evolve the long-term scalability and developer experience of the React Native monorepo, enabling seamless concurrent development for 50+ mobile engineers across multiple squads.

Future-Proof Shared Code: Maintain and scale the monorepo to host shared npm packages designed for future cross-platform code sharing with web repositories. Champion CI/CD & Developer Experience: Maintain and optimize our current CI/CD pipelines in Bitrise while helping shape our future migration to Expo. Elevate Quality & Observability: Enable product teams to make data-informed decisions by building robust tracing and dashboards in Honeycomb.

Help establish and scale end-to-end testing frameworks across the organization using Maestro. Drive Technical Alignment: Partner with Engineering Managers and Product stakeholders to review technical solutions, provide architectural guidance, and promote engineering best practices across squads. Strengthen Application Health & Reliability: Lead technical efforts to improve application health and reliability by designing observability tooling, performance reporting, incident response practices, and operational guardrails that improve system stability.

Pragmatic Technical Governance: Facilitate architectural decision-making, choosing the appropriate level of documentation—from lightweight design proposals to formal RFCs and ADRs—based on the scope and impact of each initiative. Contribute to 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 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. 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.

React Native & Native Mobile Expertise: Deep, production-tested expertise in React Native, combined with strong knowledge of both iOS and Android. You understand React Native's internal mechanics, performance profiling, native code bridging, platform-specific features and constraints, as well as the respective app store release processes. You are comfortable working across the full mobile stack to build and scale enterprise-grade applications.

Agentic Engineering: Hands-on experience using AI coding agents (Claude Code, Cursor, Copilot) in production or near-production work. You think beyond prompts to context engineering—structuring specifications, tool configurations, and information flow so agents produce reliable output. You can decompose complex workflows across agentic components, identify unreliable outputs, and introduce the appropriate guardrails where needed.

Scale-Minded Developer Experience: Proven track record of managing and optimizing workflows, linting, caching, and build times for large engineering organizations (50+ developers). Systems & Monorepo Thinker: Experience managing complex build configurations, white-label scaling, and monorepo architectures. High Autonomy & Accountability: You are comfortable operating with a high degree of autonomy, making sound technical decisions in ambiguous situations, and supporting teams during complex production incidents.

Deep mobile engineering expertise, with experience across the app release cycle, test automation, on-device performance and platform UX conventions. Exceptional Cross-Squad Influence: You have a proven ability to influence technical direction across multiple engineering teams through expertise, communication, and collaboration. 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). Are you the missing ingredient? If this sounds like a tasty opportunity, we’d be excited to hear from you. We aim to review your profile and respond within 5 business days.
