Base Salary
$160k - $330k/yr
Responsibilities
- Design and build a user-space, VPP-based data plane connecting microVM sandboxes to one another, Baseten services, and the internet.
- Build multi-tenant virtual private networking and EVPN, GENEVE, and VXLAN overlays across regions.
- Expose networking capabilities through a programmable API for the rest of the platform.
- Improve latency and connection scale for agent-to-agent and agent-to-service traffic.
- Build regional routing that directs requests to nearby regions and preserves connections across sandbox suspension and resumption.
- 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 layers and debug production issues end to end.
- Collaborate with compute, storage, GPU infrastructure, and datacenter teams.
Requirements
- Production experience with user-space packet processing such as DPDK or VPP, or with virtualized network functions such as VNF/NFV.
- Production experience building multi-tenant networking using technologies such as VXLAN, GENEVE, or VRF.
- Experience building a software-defined network, overlay network, or packet-processing data plane in production.
- Strong production systems programming skills in Rust, Go, and/or C/C++; network architects must be hands-on builders rather than only configurators.
- Experience building cloud networking as a provider rather than only consuming a cloud provider’s network.
- Strong 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 using packet captures, tracing, and profiling.
- Preferred experience with VPP/FD.io, GENEVE or VXLAN overlays, EVPN, Linux kernel networking, eBPF/XDP, netfilter or nftables, network namespaces, virtual machine networking, IPv6, multi-region routing, anycast, BGP, TLS termination, DNS, or egress security controls.
- Preferred background in telecom user-plane or 5G core networking, or low-latency trading networks.
Benefits
- Competitive compensation including meaningful equity.
- For U.S. employees, 100% medical, dental, and vision insurance coverage for employees and dependents.
- Flexible paid time off and a company-wide Winter Break from Christmas Eve through New Year’s Day.
- Paid parental leave.
- Fertility and family-building stipend through Carrot.
- For U.S. employees, a company-facilitated 401(k).
- Exposure to a variety of ML startups and related learning and networking opportunities.
