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.
