Tech Lead Mobile

* Drive an AI-first way of working within the team by setting standards and guardrails for AI-assisted development and exploring new AI tools and approaches.
* Ensure the app meets its quality targets and that releases are reliable, covering everything from CI/CD to staged rollouts.
* Act as the app's technical counterpart for the backend, identity, commerce, and loyalty teams, ensuring requirements are clearly communicated and potential gaps are identified early.
* Support and mentor engineers, share knowledge across teams, and contribute to the assessment of technical skills during recruiting as a senior expert without disciplinary responsibility.
* In close collaboration with the Product Owner, identify opportunities where AI and technology can create additional value within the app itself.

Profile:

* Several years of hands-on mobile development with deep experience in cross-platform development, ideally React Native, including at least one consumer app with a large user base shipped and run on iOS and Android.
* Experience as a Tech Lead or Lead Engineer, setting technical direction for other engineers and mentoring them, including in distributed teams.
* Solid knowledge of mobile architecture: navigation, state management, offline behaviour, performance, deep linking and push notifications.
* Proven experience connecting mobile apps to backend APIs and to customer login and identity systems, and with mobile build, release and production monitoring.
* Substantial hands-on experience developing software with AI coding assistants and agents, with the judgement to know where they help and where they don't.
* Ideally, experience with retail, e-commerce or loyalty apps, apps across several countries and languages, or migrating an existing app while keeping its users.
* Pragmatic decision-making, clear communication, and a strong sense of ownership for product quality and the customer experience.
* Business-fluent English; German is a plus.
