About the team and position 🔥
We are looking for a Senior Software Engineer (iOS) with deep iOS expertise experience to elevate platforms and lead Swile Apps to the best possible user experience. You will own user-facing features end-to-end, raise the quality bar, and push the org to operate with a consistently high bar and high performance.
Senior Mobile Software Engineers for the iOS platform at Swile are responsible for delivering the best experience to all our end users and ensuring that our iOS app performs well even on older devices, remains secure, and is stable.
We also expect you to be able to deliver well-documented, tested, high-performance code in Swift and Objective-C, following best development practices and ensuring that everyone on your team does the same through code reviews, always aiming to improve the quality of your team's deliveries.
Your day to day activities 📈
- Own and ship iOS features from problem framing → design → implementation → rollout → measurement.
- Set and enforce mobile quality targets (e.g., crash-free >99.9%, cold-start p95 down quarter over quarter, accessibility compliance, securite software).
- Lead iOS architecture and standards (modularization, design system components, networking, telemetry).
- Ship safely using feature flags, staged rollouts, server-driven config, kill switches, and clear rollback plans.
- Instrument, monitor, and alert on critical journeys (errors, latency, jank, memory/battery, app size).
- Accelerate others via design/code reviews, mentoring senior engineers, CI/build-time reductions, and clear docs.
- Partner tightly with Product/Design/Data; prototype, experiment, and make decisions grounded in user signals.
Requirements ⚒️
- 6+ years building large-scale iOS apps; track record of shipping high-impact user features.
- Expert in Swift; strong SPM expertise; strong SwiftUI/UIKit and Objective-C interop; solid concurrency (async/await/GCD) and Instruments profiling.
- Depth in networking (REST/GraphQL), offline/caching, secure storage (Keychain), privacy, and accessibility.
- Proven release/quality engineering: XCTest/XCUITest/snapshot, CI/CD, staged rollouts, feature flags, and reliable rollback.
- Demonstrated org-level influence: multi-team designs, standards adoption, mentoring seniors, raising execution pace.
- Crisp written/spoken communication; partners effectively with Product, Design, and Backend; data-driven decisions.
- C1 English.
