• Implement best practices for iOS development, including code review, automated testing strategies, and CI/CD.
• Integrate mini-apps, payments, and virtual currency systems into the Xsolla App ecosystem.
• Collaborate with product and design teams to turn business goals into native experiences.
• Work with cross-functional teams, including backend developers, QA engineers, and project managers.
• Participate in technical discussions to align development work with business objectives.

Architecture & Design

• Design and implement scalable application architecture for iOS.
• Lead architectural decisions around modularization, dependency injection, navigation, and state management.
• Configure and optimize the Xcode build graph, Swift Package Manager dependencies, and modular targets.
• Build and maintain an internal SwiftUI component library and design system implementation.
• Establish and enforce coding standards, design patterns, and best practices across the mobile development team.
• Create technical specifications and architecture documentation for complex features and systems.
• Partner with Android and React Native engineers to keep shared API contracts coherent.
• Drive observability for mobile: structured logging, crash monitoring, performance tracing, and release health dashboards.

AI-First Engineering

• Use AI coding agents and assistants as a core part of your daily workflow.
• Build and maintain the context that makes agents effective in our codebase.
• Prototype and ship AI-powered product features using Core ML and server-side LLMs.
• Design evaluation and guardrails for AI features.
• Mentor engineers on AI-assisted development and help set quality-preserving standards.

Qualifications

• 5+ years of professional iOS development experience, with deep expertise in Swift.
• Proven track record of shipping commercial iOS applications.
• Strong command of modern Apple frameworks: SwiftUI, Swift Concurrency, Combine, UIKit interop.
• Strong understanding of iOS architecture patterns and state management.
• Experience with automated testing on iOS and CI/CD for iOS release pipelines.
• Solid grasp of performance, memory, and energy profiling using Instruments.
• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent experience).
• Proven use of AI coding agents and AI-assisted development tools.
• Experience with third-party integrations, REST/GraphQL APIs, and mobile SDK consumption.
• Strong problem-solving abilities and a results-driven approach.
• Effective communication skills, both written and verbal.

Nice to Have

• Experience with widgets, App Intents, Live Activities, push notifications, or deep linking at scale.
• Experience bridging Swift modules into React Native, or with Kotlin Multiplatform on the iOS side.
• Familiarity with StoreKit 2 and Apple’s in-app purchase entitlements.
• Familiarity with gaming ecosystems, virtual currency platforms, and digital commerce flows.
• Experience with mobile security practices.
• Contributions to open source, technical writing, or conference talks in the mobile or AI engineering space.

Benefits

• Comprehensive Benefits Program including medical, dental, and vision.
• PTO and a personalized career roadmap for each employee.
