AR​/VR, Software Development Engineer

Sunnyvale, California, United States Software and Services

Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other's ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better.

It's the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you'll do more than join something — you'll add something.

Join our Systems Software Architecture Team under VPG, where we're pioneering a revolutionary framework that's redefining how Apple products deliver real-time experiences. Our framework enables developers to express workloads as interconnected graphs, creating demand-driven systems that optimize for latency and enable zero-copy data access. Originally developed to help vision

OS achieve its critical motion-to-photon latency targets—providing users with a seamless, realistic experience through Vision Pro—our technology is now expanding to iOS and macOS. As Apple deploys LLMs and other real-time features across platforms, our framework is becoming essential infrastructure that enables the next generation of Apple product experiences.

As a Systems Framework Engineer, you will design and develop critical framework features that power real-time experiences across Apple's product ecosystem. You'll collaborate with cross-functional teams to architect solutions for products like Vision Pro, iPhone, and Mac, creating systems that meet demanding performance requirements for latency, jitter, and user experience. This role requires deep technical expertise in systems programming, the ability to navigate complex architectural tradeoffs, and a passion for delivering technology that enables breakthrough product features.

• Design and implement framework features that enable customer-facing capabilities on vision
  
  OS, iOS, and macOS platforms.
• Develop code using C/C++, Objective-C, and/or Swift.
• Create architectural RFCs that describe how product features operate and guide the team in developing framework features.
• Collaborate with cross-functional partners to understand requirements and deliver optimized solutions.
• Triage and prioritize incoming issues based on metrics including MTBF, client team impact, user experience, and test coverage.
• Evaluate tradeoffs between different technical approaches and provide guidance on optimal solutions for complex problems.
• Optimize system performance to meet critical KPIs for latency, jitter, and resource utilization.

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, or related field, or 3 years of equivalent work experience.
• Strong foundation in operating systems fundamentals including process management, memory management, inter-process communication, concurrent programming, and synchronization primitives.
• Proficiency in C/C++ programming for systems-level development.
• Experience with debugging tools such as gdb or lldb.
• Ability to analyze system performance and identify bottlenecks.

• Deep understanding of computer architecture and hardware-software interaction.
• Experience with resource-constrained Embedded Systems development, and delivering performance-critical features in production systems.
• Knowledge of real-time systems design principles and scheduling algorithms.
• Background in safety-critical systems development and verification.
• Experience with AR/VR systems, spatial computing, or graphics pipelines.
• iOS or macOS development experience using system frameworks.
• Proficiency in Objective-C or Swift for platform development.
