Technical Operations Engineer (Solana)

QuickNode is a global, remote-first blockchain infrastructure company operating high-performance validators, RPC services, and indexing pipelines for large-scale Web3 applications. This role focuses specifically on Solana production operations—ensuring validators, RPC nodes, and related hardware deliver low-latency, reliable performance at scale.

The position involves deep systems-level work across Linux, kernel tuning, hardware optimization, and Agave/Jito configuration, along with tooling development in Go or Python. You’ll manage incident response, support 24-hour regional operations, automate key workflows, and collaborate with ecosystem contributors to improve reliability.

Candidates should have strong experience running distributed systems, familiarity with Solana’s client stack, and the ability to analyze performance metrics while maintaining operational safety and resilience.

🔹 Responsibilities

• Operate, upgrade, and tune Agave/Jito validators and maintain healthy voting/leader performance.
• Manage high-throughput RPC nodes by optimizing queues, connection limits, caching, and PubSub behavior.
• Configure and tune hardware components (CPU, RAM, NVMe, NIC) and validate performance improvements with metrics.
• Automate workflows including snapshot pipelines, image builds, Terraform/Ansible configuration, and replay/state-sync checks.
• Lead incident response (SEV0–2), perform safe rollouts/rollbacks, and publish clear RCAs with preventive fixes.
• Troubleshoot protocol issues, coordinate with Solana ecosystem contributors, and patch clients when necessary.
• Develop Go/Python/Bash tools for operations, validation, monitoring, and recovery tasks.
• Maintain secure key management practices using KMS/HSM/Vault and support DR/backup processes.

🔹 Requirements

• Strong Linux fundamentals and experience with kernel tuning (NUMA, IRQ affinity, hugepages, CPU sets, schedulers).
• Hands-on hardware tuning experience, including BIOS, NIC offloads/queues, NVMe layout, and performance debugging.
• Solana operations background: Agave/Jito builds, snapshots, ledger repair, accounts-DB tuning, version management.
• Understanding of protocol surfaces such as JSON-RPC, gRPC, PubSub, concurrency limits, timeouts, and backpressure design.
• Familiarity with transaction routing (QUIC/TPU), fee strategies, compute budget settings, and simulation/preflight trade-offs.
• Ability to build small tooling in Go or Python; comfort with Bash scripting.
• Experience with observability tools like Prometheus/Grafana and implementing SLO/error-budget-driven alerting.
• Evidence of operating production systems with safe rollout practices and tested DR paths.
• Willingness to support follow-the-sun operations with minimal travel (typically <10 days/year).
• Compensation is region-adjusted; eligible for quarterly bonuses based on company and individual goals.
