DevOps Engineer, Solana Validator + Stakepool

We’re seeking a DevOps Engineer to join our team. You'll be responsible for end-to-end operation of validator nodes and stake pools with an emphasis on uptime, security, and performance. You'll help scale a globally distributed fleet of nodes, interfacing with both hardware and cloud deployments, and contribute to building a best-in-class staking experience for our delegators.

• Operate and monitor Solana validator nodes across testnet and mainnet environments.

• Launch and manage a Solana stake pool; monitor inflows/outflows, delegate communications, and pool performance.

• Maintain highly available, secure infrastructure—both in cloud and hosted bare metal environments.

• Build and manage observability tooling, including dashboards, alerting, and logging systems.

• Automate deployment and updates of validator software using infrastructure-as-code principles.

• Collaborate with network and protocol engineers to support client upgrades and ecosystem initiatives.

• Ensure rigorous security standards, backups, and failover strategies are in place.

• Analyze rewards, vote credits, and uptime metrics to optimize validator competitiveness.

• Proven experience operating Solana validators, especially using bare metal providers, and familiarity with the Solana CLI.

• Strong Linux system administration skills, with knowledge of networking fundamentals.

• Proficiency with containerization and orchestration tools (e.g., Docker, Kubernetes).

• Experience with monitoring and alerting tools (e.g., Grafana, Prometheus).

• Comfort automating infrastructure using tools like Ansible, Terraform, or similar.

• A good grasp of blockchain staking mechanics and validator incentive models.

• Ability to respond to incidents and recover from downtime independently and quickly.

• Experience contributing to or managing validators on other proof-of-stake networks.

• Understanding of consensus mechanisms, slashing conditions, or MEV.

• Familiarity with ZK, privacy-preserving protocols, or L1/L2 blockchain architectures.

• Basic coding or scripting abilities (Python, Bash, Go, or Rust).

• Help architect the infrastructure powering a decentralized, high-performance internet.

• Join a globally distributed, technically advanced team solving real-world networking challenges.

• Competitive compensation + significant token upside.

• Flexible remote work with optional off-sites and team meetups.

ABOUT DOUBLEZERO

DoubleZero is a decentralized, permissionless protocol that revolutionizes network performance for distributed systems like blockchain. The mission is simple: increase bandwidth and reduce latency.

DoubleZero increases bandwidth by filtering junk data that currently plagues validators and other network operators. DoubleZero reduces latency by connecting these filters with underutilized private fiber links in the form of a mesh network. By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to reach performance levels that are currently impossible.

In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself. We look forward to hearing from you.
