Equinix is seeking a Sr Principal Engineer to serve as a senior technical authority for the architecture, automation, telemetry, and continued evolution of our global corporate enterprise network, known as the GEN network.

This individual-contributor role combines deep network architecture and protocol expertise, hands-on Python automation, and applied artificial intelligence. The successful candidate will define the future-state architecture of the GEN network, establish global standards and reference designs, and lead a three-to-five-year modernization strategy.

The Sr Principal Engineer will bridge network engineering and software development, helping Equinix move from manual and tool-specific practices toward automated, testable, observable, policy-driven, and AI-augmented network operations.

This role requires a mature technical leader who can evaluate complex network designs and automation capabilities, influence global engineering teams without formal authority, and communicate architecture decisions to executives through business value, risk, cost, security, resiliency, and operational impact.

• Define the target-state architecture and multiyear strategy for the global GEN corporate enterprise network.
• Provide architectural direction across global LAN, WAN, campus, branch, wireless, corporate data center, cloud connectivity, secure access, network security, carrier services, and resiliency.
• Establish global standards, reference architectures, design patterns, technical guardrails, and architecture-governance practices.
• Identify technical debt, lifecycle risks, capacity needs, architectural constraints, and modernization opportunities.
• Own most corporate network architecture decisions while aligning with security, cloud, infrastructure, enterprise architecture, risk, and other Equinix standards.
• Evaluate architecture alternatives and emerging technologies based on scalability, availability, security, operational readiness, cost, and measurable business value.

• Provide deep technical leadership in routing, switching, traffic engineering, control-plane behavior, network resiliency, and complex failure scenarios.
• Apply expert knowledge of BGP and OSPF, with strong working knowledge of IS-IS and large-scale routing concepts.
• Guide architecture involving EVPN, VXLAN, leaf-spine fabrics, Layer 2 and Layer 3 boundaries, multihoming, segmentation, SD-WAN, cloud interconnection, and high-speed networking.
• Personally write, review, troubleshoot, or materially guide Python used for network automation, telemetry, and data processing.
• Translate network requirements into reliable software-enabled workflows in partnership with network engineers and software developers.
• Establish network-as-code practices using Python, Ansible, Terraform, Git, APIs, structured data, and Git Ops.
• Define authoritative sources of truth for intended network state, inventory, topology, configuration, policy, and service data.
• Establish production controls for testing, configuration validation, drift detection, compliance, deployment, rollback, and post-change verification.
• Evaluate multi-vendor and open-networking…
