Quick Facts

• Role: Senior iOS Engineer

• Start: ASAP, December, or January

• Duration: 6 months initial

• Location: Stockholm (4 days per week in the office)

Description

Join a team building a global, real-time consumer app. You will write modern Swift, design and ship features with SwiftUI and UIKit, and help shape a Swift-first, modular architecture.

Responsibilities

• Design and ship user-facing features in Swift using SwiftUI and UIKit, leveraging async/await.

• Translate complex requirements—real-time data, map interactions, and push alerts—into reliable, performant code.

• Drive architecture discussions (MVVM, modularization, dependency injection) and evolve the codebase.

• Write unit, snapshot, and UI tests; raise quality through code reviews and pair programming.

• Collaborate daily with Android, designers, backend engineers, QA, and product to deliver cohesive cross-platform experiences.

• Maintain and improve CI/CD with Fastlane and Xcode Cloud for fast, predictable, safe releases.

• Mentor mid-level engineers and share knowledge via RFCs, tech talks, and documentation.

Requirements

• 5–8 years of iOS experience shipping high-quality, high-traffic consumer apps.

• Expert Swift skills with deep experience in both SwiftUI and UIKit and the trade-offs between them.

• Strong modern concurrency knowledge: async/await, structured concurrency, and actors.

• Experience with MVVM, Clean Architecture, Coordinator patterns, and dependency injection.

• Hands-on testing experience: XCTest, snapshot testing, and CI/CD tooling.

• Performance profiling experience using Instruments (CPU, memory, rendering).

• Strong collaboration and feedback skills.

Bonus

• Real-time mobile data experience (live feeds, websockets, high-frequency UI updates).

• MapKit or third-party map SDKs and custom map-layer performance tuning.

• Background modes, Core Location, push notifications, and Live Activities.

• StoreKit 2, App Store optimization, or experimentation frameworks.
