Senior Mobile Engineer (Swift and/or Kotlin)

Exerizon is a fast-growing strategy and technology consulting firm founded by former senior leaders from global consulting and cloud organizations. We help current and future market leaders tackle their greatest challenges — from digital strategy and cloud transformation to data & AI platforms and application modernization. We redefined the traditional consulting model: we share risk with our clients through impact-based remuneration, and we share ownership with our people from day one.

We are looking for a Senior Mobile Engineer to build and modernise native mobile apps for our clients in banking, insurance and healthcare — on iOS ( Swift ), Android ( Kotlin ), or both. You will work on apps that are the client's primary customer channel: high traffic, strict security and regulatory requirements, and real consequences when a release goes wrong.

Design and build native apps in Swift (SwiftUI, UIKit) and/or Kotlin (Jetpack Compose) — new features, modernisation of legacy codebases, and rewrites where they are justified Own the architecture on your platform: modularisation, MVVM / Clean Architecture / TCA, dependency injection, offline-first and data sync strategies Build and evolve server-driven UI (SDUI) : design component schemas with backend teams (JSON or Protobuf), own the client-side rendering engine, handle schema versioning, backward compatibility and graceful fallbacks — so product teams ship new journeys without an app release Practise AI-driven dev
