Role summary
We are seeking a Sr. Tools & Automation Engineer to join our iCloud Quality Engineering team. You will be responsible for building, owning, and evolving the test automation ecosystem for iCloud's core products across iOS, macOS, and the web. This role involves designing frameworks, tools, and infrastructure to ensure reliable and scalable testing, with a focus on applying AI to testing workflows.

You will work in a fast-paced environment, adapting to changing priorities and enhancing the effectiveness of surrounding engineers.
Description
We are looking for a Tools and Automation Engineer to build, own, and evolve the test automation ecosystem for iCloud's core products across iOS, macOS, and the web. You will design the frameworks, tools, and infrastructure that make testing reliable and scalable across large, complex systems, and you will apply AI to how tests are written, run, and triaged. The ideal candidate is a strong software engineer first. You have deep experience building production-quality automation, and you debug problems across every layer of the stack. You can own a project end to end: deciding what needs to be automated, designing and delivering it, and producing a signal people trust when they make release decisions. You work well in a fast-paced environment, adapt quickly when priorities change, and make the engineers around you more effective.
Minimum Qualifications
4+ years of experience in test automation, software development in test, or quality engineering. Strong programming skills in Python, Swift, or a comparable language. Proven track record of building and maintaining production-quality automation code. Experience designing and building automated test frameworks and tools, not only writing tests within existing ones. Experience writing test plans and creating automated UI tests with XCTest, WebDriver, or equivalent tools. Solid understanding of the software development lifecycle, testing methodologies, and QA processes. Experience working with CI systems and test infrastructure. Strong debugging, analytical, and problem-solving skills, with the ability to investigate and triage difficult problems both independently and collaboratively.
Preferred Qualifications
Experience leading quality for a cross-functional project, or owning automation for a product area end to end. Experience mentoring engineers or setting technical direction for an automation codebase. Experience integrating LLMs or agentic workflows into developer and QA tooling, such as automated failure triage, test-case generation, or log and artifact analysis. Hands-on experience using AI coding assistants to speed up test authoring, debugging, and automation development. Experience building internal developer tools or test infrastructure, such as execution platforms, test data services, or results dashboards. Familiarity with API, integration, and UI automation strategies, and with testing distributed cloud services. Hands-on experience with Apple platforms (iOS, macOS) and the web. Experience improving test reliability and reducing flakiness in large-scale environments. Excellent communication, documentation, and presentation skills. BS in Computer Science, Computer Engineering, or equivalent practical experience.
