The mission

Run and evolve our institutional-grade validator & full-node fleet across leading PoS networks. Keep us slash-free, highly available, and upgrade-ready while onboarding new chains fast and safely.

You will have the following responsibilities

  • Operate and optimize validators/full nodes for Ethereum (consensus+execution + MEV-Boost) and other PoS networks (e.g., Cosmos/Polkadot/Tezos/Cardano).
  • Engineer secure topologies (sentries/guard nodes, peer management), tune performance (DB/cache/IO), and manage archival vs pruned nodes.
  • Lead chain upgrades/forks with rehearsed playbooks, staged rollouts and rollback paths.
  • Own keys & signing pipelines (HSM/KMS, Vault, Tezos signer) with no-double-sign guarantees and rigorous access controls.
  • Build observability (Prometheus/Grafana/Alertmanager, logs), define SLOs, participate in on-call, drive post-mortems.
  • Automate via Terraform/Ansible, GitOps/CI; maintain Proxmox, Kubernetes &/or bare metal depending on chain needs.
  • Create a reusable new-chain onboarding kit (requirements → architecture → IaC → monitoring → DR).
  • Partner with Cybersecurity, Finance and Product on risk, cost and roadmap; represent us in client/ecosystem calls.

What you bring along
