Mobile Staff Product Engineer, Platform/Infrastructure (all genders)

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

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.
• You are comfortable operating with a high degree of autonomy, making sound technical decisions in ambiguous situations, and supporting teams during complex production incidents.
