Senior Engineer, iOS - Instant Rips

Description

The company is building a global digital sports platform that sells fan gear, collectibles, and trading cards, and is expanding into sportsbook and iGaming.

Its collectibles business serves over 100 million fans and is reworking how collectors find, buy, sell, and join in their hobby through live sessions at high volume.

The flagship mobile app combines live card breaks, real-time auctions, busy chat, marketplace trades, and collection management tools. It is built for peak traffic, where lag is noticed and reliability cannot slip.

You will join the Instant Rips iOS team, which owns the live-break experience: bidding, joining breaks, following a fast chat stream, and trading in the marketplace.

The iOS codebase uses SwiftUI, The Composable Architecture (TCA), Swift Concurrency, Apollo GraphQL, and a modular SPM setup generated with Tuist. The team expects engineers to use AI tools well, giving them good context and checking their output.

Responsibilities

• Build and release production iOS features for live breaks: auctions, stream viewing, chat, marketplace, and collector tools.
• Take features from API contract through reducers, SwiftUI views, tests, and release.
• Write meaningful tests, including unit tests with mocked dependencies, TCA TestStore checks, and async test patterns.
• Review pull requests, flag real defects, rank issues by impact, and guide others on what can be let go.
• Help shape architecture decisions on modularization, effect management, and failure handling.
• Mentor earlier-career engineers and raise the quality bar across the team.

Requirements

• 5+ years building consumer iOS applications at scale.
• Practical experience with AI development tools, including LLM improvement loops and Xcode command line integration.
• Swift Concurrency: async/await, structured concurrency, Sendable, and Swift Macros.
• SwiftUI: stateless and stateful view patterns, NavigationStack, and performance-minded composition.
• TCA: Reducer, Store, Action, and State, effect management, parent-child delegation, and TestStore testing.
• Apollo GraphQL for iOS: schema-driven development, Swift codegen, and subscriptions.
• SPM multi-package architecture with feature modules, local packages, and clean dependency graphs.
• Tuist or XcodeGen for project generation, with no committed.xcodeproj.
• CI/CD pipelines such as Bitrise or Fastlane, or equivalent automated build and test setups.
• Static analysis with SwiftLint, Periphery, or equivalent code quality gates.
• Structured commit and PR habits tied to a tracker such as Linear or Jira, or equivalent.
• Bonus: experience with livestreaming, real-time auctions, or high-throughput WebSocket or subscription workloads.
• Bonus: exposure to marketplace or e-commerce iOS applications.
• Bonus: a passion for sports cards, collectibles, or live commerce.
