Full Job Posting

  • Design, build, and maintain our native iOS application in Swift and SwiftUI, used by players and developers worldwide.
  • Deliver high-quality features on time throughout the development lifecycle, from technical design through release and post-launch iteration.
  • Own the full iOS release process: code signing, provisioning, TestFlight distribution, App Store review and submission, phased rollouts, and crash triage.
  • Implement best practices for iOS development, including code review, automated testing strategies, and CI/CD with Xcode Cloud, Fastlane, or equivalent.
  • Integrate mini-apps, payments, and virtual currency systems into the Xsolla App ecosystem.
  • Collaborate with product and design teams to turn business goals into experiences that feel genuinely native.
  • Work with cross-functional teams, including backend developers, QA engineers, and project managers, and communicate effectively across distributed, multi-timezone teams.
  • Participate in technical discussions to align development work with business objectives.
  • Design and implement scalable application architecture for iOS with a focus on maintainability, performance, and developer experience.
  • Lead architectural decisions around modularization, dependency injection, navigation, and state management (MVVM, TCA, or Observation-based approaches).
  • Configure and optimize the Xcode build graph, Swift Package Manager dependencies, and modular targets for fast, incremental builds.
  • 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 the Android and React Native engineers to keep shared API contracts, design tokens, feature flags, and analytics schemas coherent across the app family -without flattening the platform into a lowest common denominator.
  • Drive observability for mobile: structured logging, crash monitoring, performance tracing, and release health dashboards.
  • Use AI coding agents and assistants as a core part of your daily workflow, and raise the bar for how the team prompts, reviews, and verifies AI-generated code.
  • Build and maintain the context that makes agents effective in our codebase: project rules, tool integrations, reproducible dev environments, and automated checks that catch what review misses.
  • Prototype and ship AI-powered product features using Core ML, the Foundation Models framework, and server-side LLMs - with a clear eye on latency, cost, privacy, and offline behavior.
  • Design evaluation and guardrails for AI features, including prompt regression testing, fallback behavior, and handling of model failure modes in production.
  • Share what works: mentor engineers on AI-assisted development and help set practical, quality-preserving standards for the organization.
  • 5+ years of professional iOS development experience, with deep, hands-on expertise in Swift.
  • Proven track record of shipping commercial iOS applications, with apps you built currently live in the App Store.
  • Strong command of modern Apple frameworks and idioms: SwiftUI, Swift Concurrency, Combine, UIKit interop, and the Observation framework.
  • Strong understanding of iOS architecture patterns (MVVM, Clean Architecture, unidirectional data flow), dependency injection, and state management.
  • Experience with automated testing on iOS - XCTest, Swift Testing, snapshot and UI tests - and with 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, daily use of AI coding agents and AI-assisted development tools (e.g. Claude Code, Copilot, Cursor) to accelerate real production work - scoping tasks for agents, critically reviewing AI-generated code, and measurably increasing your own and your team’s velocity.
  • 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.
  • 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 and external purchase link entitlements.
  • Familiarity with gaming ecosystems, virtual currency platforms, in-app purchases, or alternative payment and digital commerce flows.
  • Experience with mobile security practices: secure storage, certificate pinning, obfuscation, and fraud prevention.
  • Contributions to open source, technical writing, or conference talks in the mobile or AI engineering space.
  • Criminal history check
  • Employment verification
  • Education verification
  • Accessing confidential company data
  • Ensuring compliance with regulatory requirements
  • Handling sensitive financial information/ managing budgets /accessing funds
