Software Engineer II, App Platforms (IOS)

Wayfair•Boston, MA

4d•Hybrid

About The Position

The App Platforms team plays a pivotal role in the seamless functioning of Wayfair's suite of 10+ native Android and iOS apps. We act as a force multiplier for the rest of the mobile organization. While we own the "paved road" infrastructure that ensures efficient builds and releases, our primary mission is providing the core libraries, frameworks, and architecture that feature teams rely on to build delightful user experiences. 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.

Requirements

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 Haves

Experience with GraphQL (Apollo).
Exposure to Snapshot testing or UI testing frameworks.
Experience writing scripts to automate manual tasks.

Responsibilities

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.
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.
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.
