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 Run and grow our bare-metal fleet: provisioning, networking, storage and capacity planning
Keep our latency and uptime promises honest with real measurement and alerting
Operate Solana and Hyperliquid node infrastructure, including upgrades and incident response
Automate everything that gets done twice, from provisioning to failover
Design private networking and peering so data takes the shortest path
Handle escalations and take part in a sane on-call rotation
Advise clients on infrastructure during consulting engagements
What we are looking for Years of hands‑on experience running production infrastructure, ideally bare metal as well as cloud
Strong Linux fundamentals: networking, storage,



performance tuning and debugging under pressure
Experience with infrastructure as code and configuration management
Comfort with monitoring and observability stacks, and opinions about what to alert on
A track record of being calm and practical during incidents
Able to work from our Toronto office part of the week
Nice to have Experience running blockchain nodes or validators at scale
Familiarity with high‑performance networking, kernel tuning or DPDK‑style work
Experience with Kubernetes and with deciding when not to use it
Background in data centre selection, peering and transit negotiation
Scripting or systems programming in Go, Rust or Python
Who you are You think uptime numbers should be measured, not marketed
You would rather automate a task than document a manual process
You stay calm when the pager goes off and honest in the postmortem
You enjoy squeezing latency out of systems most people consider fast enough
You like owning things end to end

2 Deep‑dive conversation about systems you have run and incidents you have handled
