Infrastructure Engineer - Labs
Etched · San Jose
About this role
## About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference—backed by hundreds of millions from top-tier investors and staffed by leading engineers. ## Job Summary Every Etched system starts its life in a lab. Before a rack-scale inference product reaches a customer, it goes through bring-up, validation, and testing in our factories, labs, or data centers—requiring networked, provisioned, monitored infrastructure ready before the hardware arrives. As an **Infrastructure Engineer (Infra Labs)**, you’ll own the racks and server infrastructure across Etched’s labs and data center sites—from our office lab at Santana Row to our hardware facility in Milpitas and our Bay Area colocation footprint. Once forward-deployed engineers install a system, you’ll take it from there: connect it to the network, provision it, integrate it with storage and compute dependencies, and ensure it’s observable and healthy through bring-up and testing. **This is hands-on, full-stack infrastructure delivery** in environments that change every week. It is **not** a cloud role and **not** a production SRE role. ## Key Responsibilities - Own management and support of racks and server infrastructure across labs and data center sites (from handoff through bring-up, validation, and testing). - Deliver full-stack infrastructure for new lab and data center sites: compute, networking, storage, and core services such as **DHCP, DNS, zero-touch provisioning, and NFS**. - Build and maintain bare-metal provisioning using **PXE/iPXE**, **DHCP**, **BMC/Redfish-driven imaging**, and **golden images** for near-zero-touch bring-up. - Troubleshoot Linux hosts end-to-end on custom/early-stage hardware (kernel, PCIe, NIC driver/firmware, bonding, storage, boot, power). Drive to root cause and document. - Bring racks onto the network: top-of-rack/uplink configuration, VLAN/IP planning, optics/cabling (with network engineers). - Diagnose physical-layer and hardware faults (link flaps, CRC errors, dirty/failed optics, power faults, coolant leaks) and coordinate repairs/RMAs. - Run shared lab compute by supporting the **Slurm** cluster (partitions, reservations, maintenance drains) and expanding storage/compute as programs grow. - Extend observability (e.g., **Prometheus, VictoriaMetrics, Grafana**) to every lab rack with dashboards and alerts for health, power, and link status. - Write infrastructure automation in **Ansible** and **Python** via reviewed, tested pull requests. - Manage software releases/changes under change control, respond to incidents, and keep runbooks, inventory, and design records current. ## Representative Projects - Stand up full infrastructure for the **Milpitas** hardware facility (network, provisioning, storage, telemetry, access) ready before first engineering cabinets. - Build a portable, containerized provisioning stack (DHCP, PXE, HTTP, ZTP) to bring up servers/switches in new labs/racks. - Plan and build lab infrastructure for bring-up of next-generation silicon so systems are reachable and imaged on arrival. - Take a colocation cage from empty to live: coordinate cross-connects/circuits, configure ToR switches/uplinks, and hand racks over ready for internal workloads. - Build a link- and hardware-health pipeline to detect rising bit error rates, C
