We are seeking a Senior Tools Engineer to help build intelligent internal platforms, automation frameworks, and developer tools that improve quality, and engineering productivity across Apple Ads.

This is a hands-on engineering role focused on building AI/LLM-powered internal tooling and automation systems across mobile, backend, API, and data platform ecosystems. The ideal candidate combines strong software engineering fundamentals with experience building scalable automation, developer infrastructure, and full-stack engineering platforms.

DescriptionIn this role, you will help build AI/LLM-powered internal tools that help to continuously understand signals across products, detecting risk patterns early, and enabling autonomous validation and recovery workflows. You will work on unifying fragmented solutions across multiple Apple Ads business lines into a single intelligence layer integrated with a unified validation platform, replacing bespoke tooling with a scalable and adaptive ecosystem accessible through prompts, APIs, and MCP servers. This role is focused on leveraging existing AI models and platforms to build intelligent internal developer tools rather than developing or training AI/ML models. We are looking for candidates who can operate effectively in ambiguous environments, drive clarity across complex problem spaces, and influence cross-functional teams through strong technical leadership and excellent communication skills, including experience partnering with senior engineers and engineering leadership.
