Responsibilities
Run validators: Deploy, upgrade, and tune EVM/Cosmos/Solana validators; manage client diversity; integrate MEV‑Boost/relays; keep latency & attestation/commit rates high
Protect keys & stake: Implement secure remote signing, slashing protection, and audited change windows; test restores and failovers regularly
Automate everything: IaC modules, golden images, CI/CD, snapshot pipelines, state‑sync validation, replay/load harnesses
Operate K8s at scale: Safe rollouts, HPA tuning, storage choices that won’t bite you; multi‑region capacity and budgets
Lead incidents (SEV0–2): Isolate fast, roll forward/back, publish crisp RCAs, and ship the change that prevents a replay
Limited rollups support: Stand up/upgrade sequencers & batchers, wire DA, manage contracts and params, and keep L1/L2 bridges healthy
Build signal, not noise: SLOs/error budgets, useful dashboards, alerts that only page when users are affected
Code where it counts: Write/extend tools; occasionally patch client bugs that affect production and upstream when needed
Qualification
Required
Location: Asia (remote-based)
Linux + Kubernetes: Debug real production—networking, storage, rollouts, performance
IaC (Terraform/Helm/Ansible): Ship repeatable infrastructure and zero‑touch deploys
Go or Python (plus Bash): Automate noise away and build small, sharp tools/CLIs
Validator operations: Operate/tune validators and sentry topologies; avoid slashing; manage peers; design backups/snapshots/state‑sync; handle client diversity and version skew
Key management & signing: Vault/HSM/KMS; Web3Signer/TMKMS/Horcrux; slashing-protection DBs; rotation and break‑glass procedures
Observability that matters: SLOs/error budgets; Prometheus/Grafana; alerts that only page when users are affected
Networking & systems depth: DNS/TLS/LB, P2P specifics (ports/NAT/conn limits), kernel/IO tuning, capacity & cost modeling
Rollups (targeted scope): Deploy/operate OP Stack/Arbitrum/Polygon CDK components (sequencer/batcher/indexer), wire DA endpoints (Celestia/Avail/EigenDA/AnyTrust), upgrade safely
Production validator ownership: Ethereum/EVM, Cosmos/CometBFT, or Solana in production
Key security in practice: Vault/HSM/KMS, rotation/backup/restore tested; principle of least privilege enforced
SLO thinking with results: Measurable improvements on alert noise, latency, attestation/commit rates, missed slots, MTTR
Tooling & code impact: Go/Python utilities, IaC modules
K8s & systems trade‑offs: Requests/limits/QoS, storage & kernel tuning, P2P connection limits, canaries/rollbacks
Targeted rollups experience: Shipped/operated OP Stack/Arbitrum/Polygon CDK components and integrated DA endpoints safely
