Software Engineer II, App Platforms (iOS)

We are seeking an experienced iOS engineer who is passionate about "how things work under the hood." Unlike a typical product role focused on customer-facing features, this role lives at the boundary of Mobile Engineering. You will spend the bulk of your time developing and maintaining the shared codebases-from Design Systems to Networking layers-that power the Wayfair app, while also pitching in to support the CI/CD tooling that delivers it.

What You'll Do:

Core Frameworks & Architecture (Primary Focus):

• Maintain & Evolve Core Libraries: You will build and support critical frameworks used by all feature teams, including our Networking Framework (Apollo integration), Logging/Performance frameworks, and Feature Toggle systems.

• Design System Engineering: Support UI consistency by maintaining our reusable Design System components, including Native Transitions, Image Fetching libraries, and core UI collections.

• Testing Infrastructure: Contribute to the stability of the app by enhancing our Testing Frameworks, specifically tooling for Unit, UI, and Snapshot testing execution.

• Privacy & Compliance: Assist in the technical implementation of privacy standards, including Cookie/Tracking policies (IDFA, GDPR) and Data Safety forms.

• Dependency Management: Ensure the health of our codebase through automatic dependency updates (Renovate) and SDK additions.

Infrastructure & Developer Experience (Secondary Focus):

• CI/CD Support: Assist in maintaining our build system deployment (Buildkite) and merge train tooling to ensure a stable development lifecycle.

• Release Operations: Collaborate with the team on release reporting, dashboarding, and troubleshooting issues with the CI/CD release process.

• Tooling: Help identify opportunities to automate workflows using local tooling (Fastlane, scripting) to increase developer productivity.

Collaboration & Best Practices:

• Code Review: Review code and provide guidance to other developers, believing that constructive feedback is the bedrock of a healthy team.

• Documentation: Ensure that documentation for framework usage and build tools stays up to date for the onboarding of new iOS engineers.

• Experience: 2+ years of professional iOS software development experience.

• Technical Foundation:

• Strong understanding of Swift , UIKit, and SwiftUI.

• Familiarity with architecture patterns (MVVM, Clean, etc.) and iOS fundamentals.

• Platform Curiosity: An interest in deep-diving into how apps are built, not just how they look. You are curious about platform build tools (Xcode, Fastlane) and SDK management.

Tooling Familiarity: Experience or strong interest in CI/CD systems (e.g., Buildkite, Circle CI) and scripting languages (Bash, Ruby, or Python) is a plus.

• Mindset: A drive to learn about new releases (WWDC), changes to iOS development, and a desire to reduce complexity for other engineers.

Nice to Have:

• Experience with GraphQL (Apollo).

• Exposure to Snapshot testing or UI testing frameworks.

• Experience writing scripts to automate manual tasks.
