Senior Director - Network Engineering

Stack

Responsibilities

• ▹Own the architecture of Lambda's global network (GPU fabrics, data center fabrics, backbone and internet edge) along with its security, performance and availability
• ▹Build multi-year roadmaps for network architecture, data center fabrics and cloud connectivity, and keep capacity ahead of demand
• ▹Set the strategy for the internet presence: peering, transit, IX footprint and backbone traffic engineering
• ▹Partner with security, product and executive leaders to align the network roadmap with business goals
• ▹Own network readiness for every AI data center build, including management, site turn-up and validation
• ▹Own the network operating and capital budgets (OpEx and CapEx) and drive cost per GPU/port/Gbps down as we scale
• ▹Own 24/7 global network operations: uptime, latency and jitter targets, on-call health, incident response and blameless postmortems
• ▹Establish the telemetry and monitoring architecture that finds and mitigates risk proactively
• ▹Drive an automation-first engineering culture built on Infrastructure-as-Code pipelines, declarative configuration management and version-controlled automated testing
• ▹Own company-level goals for network security posture, network health and traffic engineering capability
• ▹Partner with the CISO organization to embed secure-by-design segmentation, zero-trust edge patterns and SASE frameworks
• ▹Lead multi-disciplinary network and software engineering teams, and hire, develop and retain engineers and the leaders who manage them
• ▹Manage through leads and senior ICs: regular 1:1s, clear performance feedback and growth planning
• ▹Partner with Principal Engineers and technical leadership to hold a high engineering bar across design, operational reliability and change safety
• ▹Represent your org's work and technical direction to senior leadership, and to enterprise customers and partners where appropriate

Requirements

• ▹8+ years designing and operating highly available, large-scale networks for cloud infrastructure or enterprise network architecture, including leading network engineering teams and 2+ years managing managers
• ▹Deep expertise in data center and cloud networking (BGP, EVPN/VXLAN, Clos and spine-leaf fabrics, software-defined networking, traffic engineering), plus zero-trust security, network automation and cloud platforms such as AWS or OCI
• ▹Designed or operated high-performance fabrics at scale (internet, backbone, RoCEv2 or InfiniBand)
• ▹Proven track record of building and scaling engineering organizations that deliver mission-critical, high-performance cloud connectivity
• ▹Owned network capital and operating budgets, and can negotiate with and manage hardware, optics, transit and colocation vendors
• ▹Foster a data-driven, automation-first, AI-enabled, high-velocity organization
• ▹Translate ambiguous business and product goals into clear team priorities and executable engineering plans
• ▹Strong judgment about when to go deep technically, when to delegate and when to escalate
• ▹Track record of project and product delivery in fast-paced, high-pressure environments
• ▹Excellent written and verbal communication
• ▹BS or MS in Computer Science, Electrical Engineering or a related field, or equivalent practical experience

Nice to have

• ▹Experience in GPU cloud, HPC or AI/ML infrastructure environments
• ▹Deep familiarity with large-scale data center build-out: fabric deployment, structured cabling and optics, commissioning, capacity modeling or network supply chain
• ▹Experience running peering and transit strategy for a global network, including IX presence, ASN and IP address management, and DWDM or dark-fiber backbone
• ▹Hands-on depth with the platforms the teams use: Arista / Juniper / Cisco / NVIDIA Spectrum-X and Quantum / SONiC or white-box, Terraform, Ansible and streaming telemetry (gNMI/OpenConfig)
• ▹Experience taking a network through SOC 2, ISO 27001 or FedRAMP, or meeting data-sovereignty requirements across regions
• ▹Prior experience at a high-growth infrastructure or cloud company
