Job description

We are seeking a Software Development Engineer in Test (SDET) to help drive quality across core kernel and hardware technologies within the Darwin Kernel organization. In this role, you will partner closely with cross-functional teams across Apple to proactively define test strategy, develop robust automation, execute validation plans, and deliver clear, trustworthy quality signals for complex, low-level systems. The Darwin Kernel QE team owns the quality of features and projects delivered by the broader Darwin Kernel engineering organization. As an SDET, you will be responsible for investigating and triaging test failures, diagnosing kernel and infrastructure-level issues, improving test frameworks, and building automation that enables fast, reliable feedback throughout the development lifecycle. This role requires strong technical depth, excellent communication skills, and a systems-level mindset. You will work independently on ambiguous problems, influence quality decisions across teams, and help raise the overall bar for kernel validation. The ideal candidate is technically curious, detail-oriented, and motivated to make a measurable impact on the stability and reliability of Apple’s system software. Proven ability to independently manage QA efforts across cross-functional teams. Skilled at communicating quality status to stakeholders with strong project and time management skills. Skilled in testing methodologies, test planning, and defining validation strategies. Excellent analytical, problem-solving, and debugging skills, and experience with programming languages like Python and C. Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field. Skilled at communicating quality status to stakeholders with strong project and time management skills.
