SR Technical Operations Engineer; Validators & Rollups

Overview

Pearster is seeking a Senior Technical Operations Engineer (Validators and Rollups) to help power the core systems of a major US blockchain player. The company is a cloud-based infrastructure provider that powers the global blockchain ecosystem, aiming to enable next-generation, Web3-enabled businesses and applications using blockchain technology.

Keep validators online and un-slashable. We run production validators across L1/L2s and a focused set of rollups. You’ll run Kubernetes at scale, ship IaC, lead incidents, and build tooling that makes production boring—while guarding keys, latencies, and SLOs.

• Run validators:
  Deploy, upgrade, and tune EVM/Cosmos/Solana validators; manage client diversity; integrate MEV-Boost/relays; maintain high latency & attestation/commit rates.
• Protect keys & stake:
  Implement secure remote signing, slashing protection, and audited change windows; regularly test restores and failovers.
• Automate everything:
  IaC modules, golden images, CI/CD, snapshot pipelines, state-sync validation, replay/load harnesses.
• Operate Kubernetes 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 changes that prevent 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.

• 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;
  Web3
  
  Signer/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/Eigen
  
  DA/Any Trust), upgrade safely.

• Impact:
  Your work lights up production; chain launches, reliability wins, performance gains.
• Pace >
  Ceremony:
  Tight reviews, practical standards, minimal meetings, async-first.
• Growth:
  Own big surfaces; learn protocol internals while leveling up distributed systems chops.
• Remote-first:
  Follow-the-sun coverage; humane on-call.

• Work from anywhere with true flexibility and freedom.
• Earn in USD with compensation that matches your expertise.
• Recharge confidently with dedicated paid time off.
• Advance your career with fully covered international certifications.
• Access coworking spaces worldwide whenever you want a professional setup.
• Strengthen your English and expand your global reach.
• Connect and have fun with activities that unite our international team.
• Feel appreciated with personalized gifts and a thoughtful welcome kit.
• Grow our community and earn through our referral program.
