The posting, as Volta wrote it

ABOUT VOLTA

Volta is the category-defining, fully vertically integrated AI infrastructure platform – from capital to clusters to software, under a founder-led enterprise. Our mission is The Utility of Compute™: AI infrastructure as dependable and available as electricity, for every organization that needs it. Launched with a $10B strategic partnership with one of the leading frontier AI labs, a Series A led by Andreessen Horowitz, and a $5B AI Infrastructure Fund, Volta is building the infrastructure layer of the AI era from the ground up. We are 100+ people across London, Palo Alto, and New York, with rapid growth expectations to hundreds.

ABOUT THE ROLE

Volta builds and operates large scale GPU compute infrastructure for AI workloads. A single cluster is tens of thousands of GPUs, hundreds of switches, and tens of thousands of cables. At that size you cannot manage the fabric by hand, and you cannot find out whether a design works by deploying it.

This role builds the model and the tooling that make large topologies tractable: a machine readable source of truth for every site, generated configuration that flows from it, and a simulated fabric where changes are proven before they touch hardware. You will write the software that lets a handful of engineers run fabrics that would otherwise need a room full of people.

WHAT YOU WILL BE DOING

• Own Volta's network source of truth: the data model covering sites, racks, devices, interfaces, cabling, addressing, and rail-optimized topology, and keep it authoritative rather than descriptive.
• Generate device configuration from that model for every platform in the estate, so that config is an output of the model and never edited in place.
• Build and operate a simulation environment that reproduces full cluster topologies, and make pre-deployment validation of fabric change a normal step rather than an exception.
• Build the CI pipelines that validate network change: schema and policy checks, generated config diffs, simulated convergence, and reachability and routing assertions before merge.
• Detect and close drift between intended state and device state across sites, and make divergence visible rather than discovered during an incident.
• Automate bring-up verification with the bring-up teams: cable plan generation, LLDP based cabling validation, link quality and error checks, and acceptance test suites that produce a pass or fail against the design.
• Build the tooling that turns a new site from a design document into a provisioned fabric, and shorten how long that takes with each deployment.
• Instrument the fabric: streaming telemetry collection, topology aware metrics, and tooling that lets the team reason about a fabric of this size.
• Write production Python or Go in shared repositories, under the same review, testing, and CI standards as the rest of platform engineering.
• Support incident response and root cause work where modeling, simulation, or config his
