Full Job Description
Description

You will join a team chartered to make Apple's hyper-scale cloud network dramatically more fault-tolerant by building systems that detect and remediate failures automatically, with minimal or no human intervention. This means designing and building the sensing, decision-making, and remediation layers that allow the network to identify anomalies, localize root cause, and take corrective action in real time.

You'll work on problems like: how do you detect a degrading network path before it causes an outage? How do you safely automate remediation actions on live production infrastructure without introducing new risk? How do you build a system that learns from past incidents to prevent recurrence? These are open, hard problems, and you will be expected to bring rigorous thinking, creativity, and strong engineering execution to solve them.

This role is ideal for someone who loves taking a deep, formal understanding of distributed systems, control theory, graph algorithms, or fault-tolerant design patterns and turning it into resilient, real-world software running in production at enormous scale. You should be comfortable reading research papers and translating relevant ideas into working systems, while also being pragmatic about the constraints of operating in a live, hyper-scale environment.

If you have exceptional technical depth from your academic background, competitive programming, research experience, or personal projects, and you're hungry to work on problems most companies aren't yet equipped to solve, this team is built for you.

Minimum Qualifications

Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent practical experience

4 to 6+ years of professional software engineering experience designing, building, and operating production-grade distributed systems and backend infrastructure

Deep foundation in computer science fundamentals, including distributed systems architecture, concurrency models, graph algorithms, and systems design

Strong proficiency in at least one systems-level or high-performance language, such as Go, C++, Rust, or Python

Direct experience designing and building fault-tolerant mechanisms, including automated self-healing, active remediation, circuit breaking, load shedding, and blast-radius mitigation for network services

Demonstrated ability to model complex failure domains, handle network partitions and split-brain scenarios, and reason rigorously about system behavior under extreme load and degradation

Practical experience with chaos engineering, fault injection, simulation-based testing, and stress testing in production or staging environments

Track record of technical ownership, including authoring design documents, driving code reviews, and leading post-mortem root cause analyses

Preferred Qualifications

Master's or Ph.D. in Computer Science, Distributed Systems, Networking, or a related technical discipline

Deep domain knowledge in cloud networking architectures, Software-Defined Networking (SDN) control planes, L3/L4 routing protocols, overlay networks, and Linux networking constructs (such as eBPF, XDP, or OVS)

Hands-on experience implementing or tuning distributed consensus algorithms (such as Raft or Paxos) and closed-loop control systems or reconciliation controllers

Experience architecting high-throughput telemetry pipelines and automated anomaly detection systems for real-time network health analysis

Proven ability to digest academic papers and industry research, translating state-of-the-art resilience concepts into production systems

History of notable open-source contributions, technical publications, or patent filings in distributed networking and systems reliability

About Apple

Apple is a corporation that designs, manufactures, and markets mobile communication and media devices, personal computers, portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. Apple provides many products and services, including iPhone; iPad; iPod; Mac; Apple TV; a portfolio of consumer and professional software applications; the iOS and OS X operating systems; iCloud; and accessories, service, and support offerings. It sells its products worldwide through its retail stores, online stores, direct sales force and third-party cellular network carriers, wholesalers, retailers, and value-added resellers to the consumer and also sells third-party iPhone, iPad, Mac and iPod compatible products, including application software and accessories through its online and retail stores. Introduced in 1984, the Macintosh was the first widely sold personal computer with a graphical user interface (GUI). That feature and others such as an improved floppy drive design and a low-cost hard drive that made data retrieval faster helped Apple cultivate a reputation for innovation. Apple was named as the most admired company in the United States in 2008 and in the world from 2008 to 2012 by the Fortune magazine. The company was founded by Steven Paul Jobs, Steve Wozniak, and Ronald Gerald Wayne on April 1, 1976, and is headquartered in Cupertino, California.
