Responsibilities

Architect and build L4/L7 traffic platforms for ML training and inference using Envoy, Istio, and modern load-balancing techniques
Design and implement dynamic, capacity-aware, and metrics-driven load balancing strategies for HTTP, gRPC, and streaming ML inference workloads
Develop and optimize service mesh architectures for high-throughput, low-latency ML systems, including multi-cluster and multi-region topologies
Lead the evolution of client-to-server and server-to-server traffic patterns, including adoption of HTTP/3 where appropriate
Collaborate with ML and platform teams to support scalable inference, A/B traffic shifting, canarying, and adaptive routing strategies
Contribute to and upstream improvements in Envoy, Istio, Kubernetes networking, or related CNCF projects, representing Apple in the open-source community
Implement observability, telemetry, and debugging frameworks for traffic flows (latency, tail behavior, retries, backpressure, saturation)
Ensure traffic platforms are secure, resilient, and cost-efficient, supporting hybrid and multi-cloud environments at global scale
Mentor engineers and drive architectural decisions across networking and traffic-infra domains
