Our products promise things most providers will not put in writing: sub-millisecond round trips, four nines of uptime, streams that sustain over a hundred thousand messages a second. Somebody has to make those numbers true every day. That is this role.
You will run the fleet behind OpenInfra, NoLimitNodes and HyperliquidRPC: bare-metal servers, private networking, validators, RPC nodes and the observability that watches all of it. You will also advise clients on their own infrastructure when engagements call for it.
What you will do
Run and grow our bare-metal fleet: provisioning, networking, storage and capacity planningKeep our latency and uptime promises honest with real measurement and alertingOperate Solana and Hyperliquid node infrastructure, including upgrades and incident responseAutomate everything that gets done twice, from provisioning to failoverDesign private networking and peering so data takes the shortest pathHandle escalations and take part in a sane on-call rotationAdvise clients on infrastructure during consulting engagementsWhat we are looking for
