Description

Imagine what we could do together. At Apple, new ideas have a way of becoming phenomenal products, services, and customer experiences very quickly. Bring passion and dedication to your job, and there’s no telling what we could accomplish. Apple is seeking a visionary and highly experienced Software Engineer to pioneer the next generation of internet transport technologies that power Apple's services and devices. In this role, you will be at the forefront of designing, implementing, and standardizing advanced protocols, with a particular focus on QUIC, HTTP/3, and other emerging transport layers. You will influence the future of the internet by contributing to open standards (e.g., IETF), driving cutting-edge research, and ensuring Apple's services leverage the most performant, secure, and resilient network infrastructure possible. Your work will directly impact the speed, reliability, and user experience of millions of Apple customers worldwide. DESCRIPTION As a CDN Architect, you will be a key technical leader within Apple's Edge Services team, responsible for shaping the evolution of our Edge Services infrastructure. Your responsibilities will include leading the research, design, and implementation of next-generation internet protocols and network optimizations for Apple's Edge services. You will also actively participate in and influence internet standards bodies (e.g., IETF) to drive Apple's strategic Edge services initiatives. This role involves developing high-performance, production-grade network stack components and libraries in C/C++ or Rust, and collaborating with OS teams, service teams, and external partners to integrate and deploy new protocol capabilities across Apple's ecosystem. Furthermore, you will provide technical guidance and mentorship to other engineers, fostering a culture of innovation and excellence, while staying abreast of the latest advancements in internet research and technology and evaluating their potential impact on Apple's products and services. MINIMUM QUALIFICATIONS Extensive experience in Internet protocol engineering, with a strong emphasis on transport and application layer protocols. Demonstrable expertise and significant contributions to the design, implementation, and standardisation of modern internet protocols (e.g., QUIC, HTTP/3, TCP, TLS). Exceptional proficiency in C/C++ or Rust for developing high-performance, low-latency network stacks and infrastructure. Deep understanding of network architecture, congestion control algorithms, packet scheduling, and transport security (TLS). PREFERRED QUALIFICATIONS Experience with network emulation, simulation, and performance benchmarking tools. Familiarity with operating system network stack internals (e.g., Linux, macOS, iOS). Prior experience in a research-oriented or advanced development role within networking. Familiarity with proxy systems like Envoy and their integration with custom protocols. Experience with open-source projects and a history of significant contributions to the community. Strong analytical and problem-solving skills for debugging complex network issues at scale, including performance analysis and optimisation. Excellent written and verbal communication skills, especially for presenting complex technical concepts to diverse audiences and collaborating effectively in standards bodies. Proven track record of actively contributing to IETF RFCs, drafts, or similar open standards bodies.
