Senior iOS Engineer

About the team

We are a mobile-first bank, and our iOS app is a critical part of how customers experience Zopa.

Having recently completed our migration to fully native mobile, we are now focused on making our iOS platform exceptional: fast, reliable, accessible and easy for engineers to build on.

You’ll join our Mobile Platform team, which owns the infrastructure, tooling and engineering standards that sit beneath our customer-facing mobile experiences. This includes areas such as app architecture, shared modules, our design system, observability, developer tooling and CI/CD.

The team is accountable for keeping these foundations reliable, scalable and easy for our product squads to build on. You’ll help shape the direction of mobile engineering at Zopa, improve the developer experience, and reduce the underlying technical complexity that product engineers need to manage.

The Mobile Platform team does not own individual customer journeys or build product features on behalf of squads. Product teams remain responsible for their customer experiences and the services they own, including responding to incidents within those product-owned areas. Instead, your focus will be on creating and maintaining the shared capabilities, tooling and standards that enable those teams to deliver safely and effectively.

You’ll also be part of a strong iOS engineering community, contributing to standards, sharing knowledge and helping us continue to mature our native engineering practice.
