As Tech Lead App (React Native), you shape the technical direction of our mobile applications across iOS and Android, ensuring a scalable, consistent and high-performing app foundation within our digital ecosystem.
You connect product ambitions with robust mobile engineering solutions, ensuring that React Native applications, native modules, backend APIs, data flows, and third-party services work together coherently to deliver seamless customer experiences across mobile platforms.
This is a hands-on technical leadership role. You are expected to be deeply embedded in the codebase while guiding architectural decisions across React Native structure, state management, performance, native integrations, and release workflows. You understand modern mobile engineering practices well enough to challenge, guide, review, and contribute directly when needed. In short: not only leading from design discussions, but also actively shaping implementation in the real product.
You are not a gatekeeper, but a facilitator of strong engineering practices, shared ownership, and continuous improvement within the mobile domain.
About the team
You will join the Digital Architecture & Technology team, a team that works across Digital to shape scalable, secure, and maintainable technology solutions. We partner closely with product teams, engineers, business stakeholders, and external technology partners across areas such as MarTech, Customer Relations and Content & Design.

What we expect from you
We’re looking for someone who leads by example through clean code, clear thinking, and a calm, constructive way of working. Someone who naturally brings others along, rather than taking over decisions, and helps create real shared ownership within the team.
In mobile, you’re comfortable with complexity. You make pragmatic choices around performance, device differences, UX constraints, and native quirks, always keeping the user and product in mind.
You help others understand the “why” behind decisions. Technical trade-offs don’t stay hidden with you, you translate them clearly for both engineers and non-technical partners, bringing alignment instead of confusion. You balance speed with sustainability. You care about delivering today, but not at the expense of tomorrow’s stability or maintainability. And you stay curious. You follow how React Native and the wider mobile ecosystem evolves, and you take time to evaluate what’s genuinely valuable, not just what’s new
