Senior Devops Engineer - Remote Eligible

Optimum Blockchain Infrastructure Engineer

Optimum is delivering the world's first high-performance memory infrastructure for any blockchain. Powered by Random Linear Network Coding (RLNC), Optimum scales network speed, robustness, and throughput by orders of magnitude, enhancing dApp performance and end-user experience.

Co-founded by Muriel Médard, co-inventor of RLNC, and a team of industry experts, Optimum introduces a breakthrough in Web3 infrastructure. Blockchains—often called world computers—lack a critical component for infinite scalability: a real-time virtual memory.

Our memory infrastructure enables high-speed data propagation, fast access, and secure updates, scaling the world computer. Backers include 1kx, Spartan, Robot Ventures, Triton Capital (fka Kraken Ventures), Finality Capital, SNZ, and others.

Key Responsibilities

• Infrastructure Management – Deploy, operate, and scale distributed clusters of OptimumP2P nodes, gateways, and relays across multi-cloud environments.

• Automation & Orchestration – Build and maintain infrastructure-as-code (Terraform, Helm, Kubernetes) for rapid, reproducible deployments.

• Reliability Engineering – Define and monitor SLOs around propagation latency, attestation inclusion delay, and network reliability; implement automated failover and redundancy.

• Observability & Telemetry – Develop monitoring pipelines (Prometheus, Grafana, OpenTelemetry) with actionable alerts and dashboards for network health and validator-facing KPIs.

• Security & Resilience – Harden nodes, APIs, and relays against DDoS, replay attacks, and resource exhaustion; manage secrets and peer identities securely.

• CI/CD Ownership – Maintain build pipelines for services (multi-arch Docker builds, secure image publishing).

• Cross-Team Collaboration – Work closely with protocol engineers and researchers on large-scale experiments.

• Incident Response – Create runbooks, perform post-mortems, and continuously improve operational reliability.

• Programming & Tooling – Write automation scripts, custom operators, and CLI tools (primarily in Go, Python, or Bash) to enhance infrastructure efficiency and debugging workflow

Required Background

• 5+ years of experience in DevOps, SRE, or Infrastructure Engineering, ideally with distributed or high-throughput systems.

• Strong expertise in Kubernetes, Docker, and Terraform (multi-region, multi-cloud deployments).

• Proven track record in observability and monitoring (Prometheus, Grafana, Loki, ELK, OpenTelemetry).

• Deep understanding of networking fundamentals (TCP/UDP, packet loss, NAT traversal, DDoS mitigation).

• Hands-on experience with CI/CD pipelines (GitHub Actions, GitLab CI).

• Security-first mindset: IAM, secrets management, infra hardening.

• Bonus: familiarity with libp2p, gRPC, and blockchain validator infrastructure.

What We Offer

• Competitive compensation package, including token incentives

• Remote-first work environment with flexible hours

• Collaborative team culture that values innovation and growth
