The Role

QuickNode’s Tech Ops team is looking for an engineer who lives and breathes rollups. Your mission is to take a customer’s idea for a new L2 or app-chain—from “we think we want an Orbit/zkSync/CDK chain” to a live, monitored, auto-healing production deployment that delivers 99.99%+ uptime. You will design, launch, and operate rollups across the major stacks (OP Superchain, Arbitrum Orbit, ZK Stack, Polygon CDK, and more), integrate alternative data-availability layers, harden key-management, and keep everything humming at scale. If you love shipping infrastructure fast, fixing what isn’t documented yet, and working directly with foundations and builders, we want to talk to you.

What You'll Do

• End-to-End Rollup Deployments

  • Own the design, Helm/Kubernetes manifests, Terraform modules, and Ansible playbooks that spin up sequencers, batchers, provers, indexers, and supporting services.

  • Integrate DA layers such as Celestia, Avail, EigenDA, AnyTrust, etc.

• Chain Upgrades & Post-Launch Ops

  • Maintain production rollups through version bumps, parameter tweaks, smart-contract upgrades, and emergency hot-fixes while meeting 4×9 SLOs.

  • Write and refine runbooks, automated health-checks, and self-service tooling so new chains move from staging to prod in hours—not weeks.

• Monitoring, Alerting & Incident Response

  • Build Grafana/Prometheus dashboards, tune alerts, and hook everything into PagerDuty.

  • Lead incident triage and retros, digging into logs, metrics, and on-chain events to root-cause failures.

• Foundation & Customer Collaboration

  • Pair with ecosystem devs to debug protocol-level issues; submit upstream PRs when the fix lives in open-source.

  • Translate product/sales requirements into clear infra specs for customers who “just want their chain live.”

• Security & Key Management

  • Design and operate HSM- or Vault-backed workflows for sequencer & bridge keys.

  • Enforce least-privilege network and firewall policies in cloud & bare-metal environments.

• Continuous Improvement

  • Benchmark performance across cloud providers, instance types, and kernels; drive cost/perf optimizations.

  • Automate everything you touch to shrink mean-time-to-launch and eliminate snowflakes.

• On-Call Rotation

  • Participate in a follow-the-sun on-call schedule to ensure global coverage.

What You'll Bring

• Proven Experience

  • 5 + years in SRE / DevOps / Tech Ops, with at least 1 year hands-on launching or operating rollup chains (OP, Arbitrum, zkSync, Polygon CDK, etc.).

  • Deep Linux internals knowledge and comfort troubleshooting at the kernel, network, and container layers.

• Rollup & Smart-Contract Expertise

  • Clear mental model of sequencer pipelines, batchers, provers, bridges, fraud/validity proofs, and L1/L2 messaging.

  • Ability to deploy & verify smart contracts, change chain parameters, and wire up alt-DA endpoints.

• Kubernetes & IaC Mastery

  • Fluent in Helm, Kustomize, and vanilla manifests; confidence running multi-cluster, multi-region setups.

  • Terraform and Ansible power-user for repeatable infra builds; Docker is muscle memory.

• Observability & Reliability

  • Strong Grafana/Prometheus (or Datadog) skills: custom exporters, SLO dashboards, alert tuning, and incident analytics.

  • Experience integrating alerting with PagerDuty (or similar) and conducting post-mortems.

• Data & Services

  • Operational familiarity with Postgres (logical repl
