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 (Web3 Core Platforms)
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
Make mainnet boring. We launch chains, keep them fast, and fix the stuff that shouldn't break. You'll run
Kubernetes at scale
, ship
Infrastructure-as-Code (IaC)
, lead incidents, and write the tooling that keeps production sane. Occasionally patching a client or upstreaming small fixes is a plus.
This role gives you high-impact ownership of production systems, with a focus on
reliability, automation, and performance
in a fast-paced, remote-first environment.
Launch & Upgrade Chains
: Standups, hard-forks, snapshots, pruning, clean rollbacks.
Automate Everything
: Modules, golden images, CI/CD, zero-touch deployments across regions.
Run Kubernetes at Scale
: Safe rollouts, HPA/VS/Ingress tuning, capacity and cost planning.
Own Incidents
: Lead SEV0–2, publish RCAs, and implement fixes that prevent recurrence.
Build Signal, Not Noise
: Define SLOs/error budgets, create useful dashboards, and alerts that only page when user impact occurs.
Code Where It Counts
: Write or extend tools for snapshots, replay/load, state sync checks; patch client bugs in production and upstream when appropriate.
What You Bring to the Table
Location:
Global / 100% Remote
Linux + Kubernetes
: Debug real production issues including networking, storage, rollouts, and performance.
IaC (Terraform, Helm,



Ansible)
: Build repeatable, scalable infrastructure.
Programming (Go or Python + Bash)
: Automate repetitive tasks and build small, precise tools.
Blockchain Operations
: JSON-RPC internals, running/tuning RPC and validator nodes, log analysis.
Observability
: Define and monitor SLOs/error budgets, Prometheus/Grafana instrumentation.
Networking
: Strong fundamentals in DNS, TLS, load balancing; reasoning about anycast/BGP when needed.
Experience & Signals We Care About
:
Clear production ownership: understanding blast radius and rollback plans.
SLO thinking and measurable improvements in alert noise, latency, or MTTR.
Real RPC/validator operations experience (beyond laptop demos).
Tooling/code contributions that improve operations (Go/Python, IaC modules, or small upstream fixes).
Ability to explain complex failures simply and leave systems simpler.
Production experience with one or more:
EVM
(Geth/Erigon/Nethermind/Besu),
Cosmos SDK/CometBFT, Solana
(Agave/QUIC),
Substrate
Multi-cloud experience, including capacity and cost modeling that survives real-world conditions.
Benefits that Move you Forward.
We're here to amplify your brilliance, not contain it.
Work from anywhere
with true flexibility and freedom.
Earn in USD
with compensation that matches your expertise.
Recharge confidently
with dedicated paid time off.
