Engineering Manager, Networking

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the Role The infrastructure networking group designs and builds the network infrastructure for Anthropic’s Points of presence, Data Centers and Backbone. Additionally, we are responsible for Anthropic’s interconnects with and between our VPCs inside of our CSP partners (AWS, GCP, and Azure). We are responsible for the network architecture, engineering and operations. We are also responsible for all of the software that are used to deploy, manage, and operate this network. We are working across disciplines including backbone networking, long haul optical networking, data center design, and cloud networking. We're looking for an Engineering Manager to build and lead our Infrastructure Expansion team—a small, high-leverage group responsible for the network infrastructure that connects our rapidly expanding compute capacity. With our recent $50 billion commitment to AI infrastructure and new data center sites coming online, this team is critical to enabling frontier AI research at scale. This is a role with extraordinary scope and leverage. You'll be bootstrapping and maturing a team that currently operates more like an early-stage startup, establishing the charter, practices, and priorities as it grows. As our capacity buildout proceeds at unprecedented pace, you'll help ensure ML teams can seamlessly use compute across AWS, GCP, and our own data centers without worrying about underlying network complexity. If owning the whole problem and having outsized impact on our infrastructure investment sounds compelling, this role might be for you. Key Responsibilities Build and lead the team : Recruit, develop, and retain a team of exceptional engineers; establish team charter, practices, and priorities as the team matures Drive technical strategy : Partner with technical leads to prioritize work across WAN buildout, data center networking, cloud connectivity, and host networking—ensuring we're solving the right problems at the right time Ensure operational excellence : Mature the team's approach to reliability, observability, and incident response as the network becomes increasingly critical to research and production workloads Unblock research at scale : Enable ML teams to seamlessly use compute capacity across multiple cloud providers and our own data centers Communicate and coordinate : Serve as the bridge between the networking team and the broader organization—clearly articulating dependencies, risks, and progress to stakeholders Stay technically grounded : Maintain enough technical depth to understand your team's work, provide meaningful guidance, and credibly represent networking concerns in cross-functional discussions About You We're looking for a technical leader who thinks of themselves as a problem-solver and team-builder first. Minimum Requirements: 8+ years of experience in an Engineering Manager role Experience building teams in environments with ambiguity and rapid change Strong technical foundation in networking: you can credibly discuss TCP/IP, BGP, routing architectures, and network debugging at a level that earns respect from senior ICs Experience across multiple networking domains (WAN, data center networking, host networking, cloud networking), with a strong emphasis on data center networking Ability to balance technical depth with pragmatic decision-making; you know when to dive deep and when to trust your team Strong communication skills—you can translate complex technical challenges into business terms and vice versa Comfort with end-to-end ownership in environments where best practices don't yet exist Preferred Requirements: Experience at compani ...
