Software Engineer - OS and System Services

The Cloud OS System Software Team is seeking an exceptional software engineer to build and integrate software for orchestrating workloads across highly performant and energy-efficient data center systems. This collaborative role focuses on utilizing hardware acceleration for machine learning and high-performance computing. The engineer will develop and maintain system software, including runtime libraries, frameworks, and daemons, and partner with teams across Apple to scale software on a novel compute platform, laying the foundation for future cloud architecture. The role involves optimizing OS performance, scalability, and reliability for large-scale distributed systems.

Must Have

• Develop, maintain, and optimize OS-level components for data center infrastructure.
• Collaborate with cross-functional teams to improve performance, security, and resource efficiency.
• Troubleshoot and resolve low-level OS issues, networking bottlenecks, and hardware-software integration challenges.
• Contribute to the development of automation, monitoring, and diagnostic tools.
• Participate in code reviews, design discussions, and architectural decisions related to OS-level services.
• Design, implement, and maintain system daemons that manage hardware components and host processes.
• Implement robust fault detection and recovery mechanisms for hardware and daemon failures.

Good to Have

• Familiarity with init systems (systemd, launchd, upstart) and service orchestration.
• Knowledge of distributed systems, cloud computing, and large-scale data center infrastructure.
• Experience with Swift, Objective-C and Apple development tools.
• Experience with AI accelerators (GPUs, TPUs, ASICs) or distributed systems.
• Knowledge of container technologies (Docker, Kubernetes) and AI workload orchestration.

Perks & Benefits

• Comprehensive medical and dental coverage
• Retirement benefits
• Discounted products and free services
• Reimbursement for certain educational expenses (tuition)
• Opportunity to become an Apple shareholder through employee stock programs
• Ability to purchase Apple stock at a discount via Employee Stock Purchase Plan
• Eligibility for discretionary restricted stock unit awards
• Eligibility for discretionary bonuses or commission payments
• Eligibility for relocation
