Spoiler: Your next challenge in serious decentralized tech starts right here. 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 integral 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 You'll Lead and Build Keep validators online and un‑slashable. We run production validators across L1/L2s and a focused set of rollups. You’ll run K8s at scale, ship IaC, lead incidents, and write the tooling that makes production boring—while 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 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. What You Bring to the Table Location: Asia (remote-based). Linux + Kubernetes: Debug
