What this Journey Looks Like
Pearster is looking for a Senior Technical Operations Engineer (Solana) to help power the core systems of a major US blockchain player.

This company is a cloud-based infrastructure provider powering the global 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.

In this role youll help keep Solana fast and reliable in production operating validators RPC and indexing at scale. Youll tune hardware optimize Agave/Jito develop tools in Go or Python and lead incident responsestreating keys latency and SLOs with production-level precision. Experience patching clients or contributing upstream fixes is a strong plus.

What Youll Lead and Build

Run validators: Deploy upgrade and tune Agave/Jito; minimize missed slots; maintain healthy voting and high leader performance.
Operate high-throughput RPC: Set smart connection and queue limits optimize PubSub fan-out and backpressure and ensure indexers are efficiently served without starving nodes
Extract performance from hardware: Select optimal servers tune BIOS kernel NIC and NVMe configurations and validate performance gains through profiling and metrics.
Automate everything: Implement reproducible images manage fleet changes with Terraform and Ansible create snapshot pipelines verify state-sync and replay processes and build automated release systems.
Lead incidents (SEV02): Quickly isolate issues execute safe roll-forwards or roll-backs publish clear root cause analyses and implement preventive measures to avoid recurrences.
Collaborate with the ecosystem: Reproduce complex bugs share performance traces and contribute targeted patches upstream when beneficial.
Code where it counts: Develop and extend tools for snapshots replay/load and state-sync verification; patch client bugs impacting production and upstream relevant fixes when valuable.

What You Bring to the Table

Location: Europe (remote-based).
Linux systems kernel tuning: NUMA IRQ affinity hugepages cpusets I/O schedulers sysctl; filesystem/NVMe layout; BIOS/firmware setup (C-states power governors); NIC queues/offloads (RSS/RPS/XPS GRO/LRO/TSO).
Hardware performance engineering: Choose and tune CPU/RAM/NVMe/NIC; measure replay throughput p95/p99 RPC latency IOPS/egressand push them lower/faster.
Agave/Jito operations: Build from source; manage feature gates and config flags; snapshots (create/consume) ledger compaction/repair/replay health; accounts-DB tuning; version management.
Read protocols & surfaces: Operate and tune JSON-RPC (HTTP/WS) gRPC and PubSub; design connection pools concurrency limits caching timeouts and backpressure that hold under peak.
Transaction sending logic: Understand direct-to-TPU (QUIC) vs RPC sendTransaction; preflight/simulation trade-offs; priority fees and compute budget tuning; leader-schedule awareness.
Go or Python (plus Bash): Build small sharp tools/CLIs (snapshot/restore pipelines state-sync verification health checks replay/load harnesses).
Observability that matters: SLOs/error budgets; Prometheus/Grafana; alerts that page only when users hurt (RPC latency PubSub backlog missed leader slots replay stalls).
Key management & safety: KMS/HSM/Vault; authority rotations; secure backups; tested DR paths; controlled auditable change windows.
