About the role

Key responsibilities & impact

Design and build the user-space, VPP-based data plane connecting microVM sandboxes to each other, Baseten services, and the internet
Build multi-tenant virtual private networking and overlays across regions
Expose the network as a programmable API for the platform
Reduce latency and increase connection scale for agent-to-agent and agent-to-service traffic
Build routing to send requests to the nearest region and maintain connections as sandboxes suspend and resume
Build secure sandbox ingress and egress, including firewalling, static egress IPs, custom domains, and managed TLS
Build L7 proxies for request inspection, filtering, secret injection, and auditing
Own per-sandbox addressing, including IPv6, and network isolation between tenants
Build packet-path observability across guest, host, and network and debug production issues end to end
Collaborate with compute, storage, GPU infrastructure, and datacenter teams

Requirements

What you’ll need

Experience with user-space packet processing (DPDK, VPP, or similar) or virtualized network functions (VNF/NFV)
Experience building multi-tenant networking in production (VXLAN, GENEVE, VRF)
Experience building a software-defined network, overlay network, or packet-processing data plane in production
Strong systems programming in Rust, Go, and/or C/C++
Experience building cloud networking as the provider, not only consuming a cloud provider's network
Solid grounding in TCP/IP and routing
Experience building or operating proxies, load balancers, or L4/L7 gateways at scale
Experience debugging latency and throughput problems with packet captures, tracing, and profiling
Experience with VPP / FD.io, GENEVE or VXLAN overlays and EVPN, Linux kernel networking, virtual machine networking, IPv6, multi-region traffic routing, anycast, BGP, TLS termination, DNS, and egress security controls are nice to have
Ability to move fast and own a problem end to end on a small team
