Software Engineer

NO C2C OR THIRD PARTIES

Role Summary:

• Title: Automation Engineer (IC5/Principal Level)
• Location: Not specified, but assume remote or based on norms
• Urgency: High – resumes due within 48 hours

Key Responsibilities:

• Build test automation infrastructure from scratch for Yahoo Mail iOS.
• Define best practices for automated testing: what to test, how to test, and how to write testable code.
• Evaluate tools and frameworks (e.g., XCUITest, XCTest, Appium).
• Design systems that integrate with CI/CD (e.g., Git, PR workflows, Git hooks).
• Collaborate with multiple teams, offering guidance on testability, not direct management.
• Mock backend API calls to ensure stable and fast test execution.
• Work on solutions for AB testing challenges, localization, and platform variance.
• Not a black-box QA role – it's heavily engineering-focused.

Ideal Candidate Profile:

• Strong engineering background (must understand large-scale Swift + Objective-C iOS codebases).
• Hands-on experience building automation test infrastructure from scratch.
• Experience with:
• CI/CD pipelines
• Git workflows
• Mocking APIs
• Handling flaky tests
• Exposure to:
• Large-scale consumer-facing apps
• UI testing tools like XCUITest, XCTest, or Appium
• Capable of recommending architectural improvements for better testability.
• Experience navigating 15+ year-old codebases, including:
• UIKit transitioning to SwiftUI
• Objective-C being converted to Swift

Important Notes:

• This is an individual contributor (IC) role with leadership through influence, not management.
• The candidate will not implement features in the mail app, but must understand the code well enough to create solid testing systems.
• Role is a "zero to one" project – minimal current automation exists.

Responsibilities:

As an Automation Engineer, you'll be a critical contributor to the quality and efficiency of the Yahoo Mail iOS application. Your responsibilities will include:

• Leading the design, development, and implementation of a robust, scalable automation testing pipeline for the Yahoo Mail iOS app, driving comprehensive test coverage and efficient execution within our CI/CD systems.

• Architecting and evolving automated test frameworks and tools that enable continuous integration and continuous delivery (CI/CD) for mobile releases.

• Developing, maintaining, and enhancing sophisticated automated test suites for functional, regression, performance, and integration testing across diverse iOS devices, OS versions, and network conditions.

• Collaborating deeply with iOS development, product, and manual QA teams to embed automation into every stage of the development lifecycle, ensuring testability and quality are considered from inception.

• Identifying, analyzing, and triaging complex defects uncovered by automation, working closely with engineering teams to ensure timely resolution and root cause analysis.

• Mentoring and guiding other engineers on best practices in test automation, code quality, and building highly testable iOS features.

• Establishing and reporting on key quality metrics derived from automation results, providing actionable insights to leadership and cross-functional teams.

• Researching, evaluating, and advocating for new automation technologies and methodologies to continuously advance our testing capabilities and efficiency.

• Acting as a subject matter expert for iOS test automation, influencing architectural and design decisions to promote inherent testability and reliability of the application.

A little about US

***, with a strong foundation of 900 million users monthly, is in the midst of a renaissance; backed by substantial investment to drive meaningful, long-term growth, led by great products. Are you up for the challenge of writing a chapter on one of the biggest consumer product success stories in history?
