What this Journey Looks Like
Pearster is looking for a Senior Technical Operations Engineer (Validators and Rollups) to help power the core systems of a major US blockchain player.
This company is a cloud-based infrastructure provider that powers the global blockchain ecosystem. Its mission is to be the indispensable utility that enables companies and innovators worldwide to build next-generation Web3-enabled businesses and applications using blockchain technology.
What Youll Lead and Build
Keep validators online and unslashable. We run production validators across L1/L2s and a focused set of rollups. Youll run K8s at scale ship IaC lead incidents and write the tooling that makes production boringwhile guarding keys latencies and SLOs like they matter (because they do).
Run validators: Deploy upgrade and tune EVM/Cosmos/Solana validators; manage client diversity; integrate MEVBoost/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 statesync validation replay/load harnesses.
Operate K8s at scale: Safe rollouts HPA tuning storage choices that wont bite you; multiregion capacity and budgets.
Lead incidents (SEV02): 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.
What You Bring to the Table
Location: Asia (remote-based).
Linux Kubernetes: Debug real productionnetworking storage rollouts performance.
IaC (Terraform/Helm/Ansible): Ship repeatable infrastructure and zerotouch 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/statesync; handle client diversity and version skew.
Key management & signing: Vault/HSM/KMS; Web3Signer/TMKMS/Horcrux; slashing-protection DBs; rotation and breakglass 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.
Why This Role Stands Out
Impact: Your work lights up production; chain launches reliability wins performance gains.
Pace > Ceremony: Tight reviews practical standards minimal meetings asyncfirst.
Growth: Own big surfaces; learn protocol internals while leveling up distributed systems chops.
Remotefirst: Followthesun coverage; humane oncall.
The Bar: Signals We Care About
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 tradeoffs: 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.
