Proven track record with modern observability tools (Prometheus, Grafana, OpenTelemetry) and robust CI/CD pipelines. ## Description The Apple Backbone Engineering group operates one of the world's most extensive, critical, and high-performance Global Wide Area Networks (WAN). We are seeking a Senior Software Engineer to design, build, and scale our next-generation Software Defined Networking (SDN) and Software Defined Infrastructure (SDI) platforms. In this role, you will lead the architecture and implementation of distributed WAN controllers, automated configuration generation and intent-push engines, real-time streaming telemetry pipelines, and distributed control planes that govern global traffic routing, path computation, and network resiliency. If you are passionate about distributed systems, routing protocol daemons, network element programmability, and building carrier-grade platforms from the ground up, come join our team., Distributed WAN Controllers & Control Planes: Design fault-tolerant SDN controllers and state synchronization systems for global traffic engineering, dynamic path optimization, and intent-based routing Configuration Modeling & Automated State Push: Architect declarative config generation, schema validation, and transactional push engines to multi-vendor network elements using OpenConfig/IETF YANG models and gRPC Routing & Forwarding Plane Interaction: Build software controllers that can create customized routing / forwarding table views and program the control / data planes on the physical and containerized routers using gRIBI or vendor specific SDKs and APIs. IP/Optical Cross-Layer Integration: Extend controller capabilities to bridge IP and optical transport layers Streaming Telemetry & Observability: Build reliable, high-throughput telemetry and analytics pipelines using NetFlow, IPFIX, gNMI, gRPC, BMP, and OpenTelemetry that is engineered to operate at Global scale ingesting several 100s of Millions of BGP routes and flow records High-Performance Microservices & Resiliency: Implement secure, low-latency services (Go, C, Python) with TLS/mTLS, adopting SRE best practices and GitOps-driven deployment (Kubernetes, Terraform, ArgoCD). ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Exploring the Power of gRPC-Gateway for Writing RESTful Services](https://www.wearedevelopers.com/videos/2072-exploring-the-power-of-grpc-gateway-for-writing-restful-services) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) - [Boosting OpenSearch Performance: gRPC Search in Action](https://www.wearedevelopers.com/videos/1964-boosting-opensearch-performance-grpc-search-in-action) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know) - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer)
