Senior Infrastructure Engineer

Own the bare metal, networks and platforms behind OpenInfra, NoLimitNodes and HyperliquidRPC, where a millisecond is a feature and downtime is a refund.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
