Software Engineer, Networking (Agent Infra)

Job summary

Responsibilities

Every agent on Baseten Sandboxes runs in its own microVM. Agents call models, reach tools and APIs, expose services, and more and more often talk to each other. Networking built into today's cloud providers was not designed for very large numbers of isolated machines that suspend, resume, and…

• Design and build the user-space, VPP-based data plane that connects microVM sandboxes to each other, to Baseten services, and to the internet
• Build multi-tenant virtual private networking and overlays (for example EVPN, GENEVE, VXLAN) across regions
• Expose the network as a programmable API that the rest of the platform calls
• Cut latency and raise connection scale for agent-to-agent and agent-to-service traffic
• Build routing that sends each request to the nearest region and keeps connections working as sandboxes suspend and resume

What they're looking for

• 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
• You write production code: strong systems programming in Rust, Go, and/or C/C++. Network architects are welcome if they build, not only configure
• Experience building cloud networking as the provider, not only consuming a cloud provider's network
