Senior Director - Network Engineering

• 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 our 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 — so capacity lands on schedule
• Own the network operating and capital budgets (OpEx and CapEx) and driving 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 that change how we build
• Establish the telemetry and monitoring architecture that lets us find and mitigate risk proactively rather than reactively
• 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 across every layer
• Lead multi-disciplinary network and software engineering teams, and hire, develop, and retain the engineers and the leaders who manage them
• Manage through leads and senior ICs, developing both — regular 1:1s, clear performance feedback, growth planning, and sponsorship of meaningful work
• 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

You

• Have 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
• Bring deep expertise across data center and cloud networking — BGP, EVPN/VXLAN, Clos and spine-leaf fabrics, software-defined networking, and traffic engineering — plus zero-trust security, network automation, and cloud platforms such as AWS or OCI
• Have designed or operated high-performance fabrics at scale (internet, backbone, RoCEv2 or InfiniBand)
• Have a proven track record of building and scaling engineering organizations that deliver mission-critical, high-performance cloud connectivity at scale
• Have 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
• Show strong judgment about when to go deep technically, when to delegate, and when to escalate
• Have a track record of project and product delivery in fast-paced, high-pressure environments
• Communicate excellently in writing and in person — you use high-quality written artifacts to drive high-quality decisions and to get alignment on problems and solutions
• Hold a BS or MS in Computer Science, Electrical Engineering, or a related field, or have equivalent practical experience
