Software Engineer, Infrastructure Services (Cloud Network Fault Tolerance)

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.

Responsibilities:

Design and build automated detection, diagnosis, and remediation systems for network faults across a hyperscale cloud environment

Develop the decision logic and safety mechanisms that allow automated systems to take corrective action on production infrastructure with confidence

Analyze failure patterns and systemic weaknesses across the network and design software solutions to eliminate or mitigate them

Build simulation, chaos testing, and fault-injection tooling to proactively surface weaknesses before they cause real incidents

Apply formal reasoning about distributed systems, failure modes, and control systems to build robust, production-grade software

Translate emerging research and industry innovation in resilience engineering into practical systems that work at Apple's scale

Bring new ideas and approaches to the team, this is a group expected to push the boundaries of what's possible in network resiliency

Prototype and experiment rapidly, validating ideas against real production data and failure scenarios

Partner with Cloud Network production and reliability teams to understand real-world failure modes and operational constraints

Work with peer infrastructure teams to ensure self-healing systems integrate safely and effectively across the broader platform

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

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
