Role Number:

200665933-0836 The OS Performance Tools team is looking for a passionate and versatile engineer to help Apple engineers and 3rd party developers understand and improve the performance of code running across Apple's platforms (macOS, iOS, watchOS, tvOS, visionOS). The team builds software that Apple engineers and 3rd party developers use to understand & analyze performance of their code, enabling them to ship delightful experiences to Apple customers.

This role will initially focus on performance triage and analysis, with a strong emphasis on leveraging AI to scale the team's impact: automating the repetitive parts of investigation, gleaning deeper insights from diagnostics and telemetry, and connecting related issues surfaced across different systems and pipelines. We are looking for someone who is excited to learn broadly across the stack and apply that breadth to make our tools — and the engineers who depend on them — dramatically more effective. Description In this role, you will spend your time at the intersection of data, systems knowledge, and software engineering. Some days that means diving into performance diagnostics to understand why a user interaction felt slow — tracing the problem through layers of the system and surfacing a finding that helps another team ship a fix. Other days it means stepping back to ask how that same investigation could be faster, more automated, or more insightful at scale, and then building the tooling or AI-assisted workflow to make it so. You will work closely with engineers across many disciplines — systems, graphics, data, and more — learning how Apple's platforms work end to end, and translating that knowledge into tools that make the broader organization more effective. The role rewards curiosity, systems thinking, and a bias toward impact. Responsibilities Build next-generation tools to inspect, analyze, and model performance across Apple's platforms Design and ship AI-assisted workflows that scale the team's ability to surface and connect performance insights Triage real-world performance issues and surface actionable findings to the teams responsible for resolving them Identify and execute on opportunities to extend coverage — adding new instrumentation, automating analysis, and closing gaps in our tooling Collaborate with teams across Apple — hardware, kernel, frontend, graphics, data analytics, and more — to ensure tools meet the needs of the engineers who depend on them Minimum Qualifications Excellent problem-solving and critical-thinking skills Strong OS & Systems fundamentals Proficient in C/ObjC/Swift or similar language Prior development experience in Unix, Linux, macOS, or iOS Aptitude to independently learn new technologies, prototype and propose software design and solutions Passion for product quality and attention to detail Excellent spoken and written communication CS degree or equivalent experience Preferred Qualifications None Pay & Benefits At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $147,400 and $272,100, and your base pay will depend on your skills, qualifications, experience, and location. Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan. You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses — including tuition.
