Job Summary
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 replication, high-availability), Redis, and common rollup indexer DB schemas. 📍Comfortable standing up REST/gRPC services in Go/TypeScript/Python to glue components together. 📍Security Mindset 📍Hands-on with Vault, HSMs, or KMS for key custody; knowledge of secure signing workflows and secrets management.
Soft Skills
📍Clear, concise communicator who can jump into a customer call or foundation Discord and make the complex simple. 📍Thrives in fast-moving, ambiguous environments; biased toward action, but disciplined about follow-through.
