Software Development Engineer in Test - Platform System Validation

Do you have a strong interest in low-level firmware and operating systems? A desire to work on complex software features, driving a high standard of quality into Apple's products? The CoreOS Platform Enablement & Quality Engineering organization is looking for a talented and passionate software engineer to join the Platform System Validation team. As a critical member of the team, you will focus on software technologies in low-level firmware and Apple silicon domains.

Your responsibilities will span all phases of software delivery of Apple's products, from early design to product launch and beyond. You'll become intimately familiar with one or more major technologies, taking on responsibilities of test, framework, and tool development, along with influencing design decisions.

Devise a testing strategy for one or more major SoCs and products, focusing on low-level firmware, silicon features, and boot loader technologies. Gain a deep understanding of the design, requirements, and architecture. Influence the inclusion of testability into software design. Develop and automate system-level tests focused on software stress and stability. Define and drive quality metrics to track progress and improvements. Collaborate cross-functionally with systems, quality engineering, and development teams.

Assess and represent the end-user impact of issues, shaping key product decisions. Explore novel approaches to create new test frameworks, automation, and infrastructure to streamline testing. Scale the team’s test automation infrastructure to support growing hardware and workload validation needs across the organization. Develop and validate system workloads and test cycles for new hardware bring-up across multiple chip platforms. Lead architecture efforts for core test infrastructure and tooling, driving both development and operational execution from design through release.

Build and maintain tooling that integrates with CI/test frameworks to support continuous validation across hardware programs. Contribute to the team’s AI-driven initiatives, extending tooling for issue triage and workload generation for new product programs. Partner with cross-functional teams (hardware, software, program leads) to unblock validation dependencies and keep programs on schedule.
