Senior Mobile Engineer - React Native, Platform/Infrastructure (all genders)

As a Senior Mobile Engineer in the Consumer Foundations tribe, you'll join the Client Platform squad and work hands-on to help evolve our mobile platform. Alongside engineering and product teammates, you'll help move our white-labeled, multi-brand application from a native brownfield React Native setup toward a more scalable greenfield architecture. This is a chance to build strong technical foundations, contribute to shared tooling, and help a growing engineering organization ship reliable mobile software.

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.

• Contribute to Migration Work: Help execute the brownfield-to-greenfield React Native migration within our white-labeled, multi-brand application ecosystem.
• Support Monorepo Scaling: Work within our React Native monorepo to support concurrent development across multiple squads, and help maintain shared npm packages used across mobile and web.
• Strengthen CI/CD: Help maintain and improve our CI/CD pipelines in Bitrise, and contribute to the team's ongoing evaluation of a future Expo migration.
• Build Test Automation: Design and extend end-to-end test coverage using Maestro, helping raise the bar for release quality and confidence across the app.
• Improve Observability: Build and maintain tracing and dashboards in Honeycomb to help the team make data-informed decisions about app health.
• Collaborate Across Squads: Partner with your Engineering Manager and teammates to review technical solutions and bring good engineering practices into your day-to-day work.
• Support Application Health: Help investigate and resolve production issues, contributing to a culture of stability and reliability.
• Document Decisions: Write clear technical documentation — design proposals, ADRs, or lightweight write-ups — appropriate to the scope of the work.

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.
