Responsibilities:
• Infrastructure Ownership: Design, implement, and manage secure, highly available, and scalable infrastructure for blockchain nodes, sequencers, and related services.
• Automation & Tooling: Develop CI/CD pipelines, infrastructure-as-code (IaC), and monitoring systems to ensure seamless deployments and minimal downtime.
• Observability & Reliability: Build dashboards, alerts, and on-call systems to detect issues proactively and reduce mean time to recovery (MTTR).
• Security & Compliance: Apply best practices for key management, secrets management, and infrastructure hardening to protect network integrity.
• Performance & Scaling: Continuously optimize infrastructure for latency, throughput, and cost efficiency across multiple environments (testnets, mainnet, staging).
• Collaboration: Work closely with blockchain engineers, protocol researchers, and SREs to support new feature rollouts and network upgrades.
• Incident Response: Lead troubleshooting during production incidents and post-mortem reviews, with a focus on prevention and continuous improvement.
Qualifications:
Must-Have:
• 5+ years of DevOps, SRE, or Infrastructure Engineering experience.
• Strong background with cloud platforms (AWS, GCP, or Azure) and container orchestration(Kubernetes, Docker).
• Hands-on experience with Infrastructure-as-Code (Terraform, Ansible, Helm, Pulumi, etc.).
• Deep understanding of CI/CD pipelines (GitHub Actions, GitLab CI, ArgoCD, etc.).
• Strong Linux systems administration, networking, and troubleshooting skills.
• Proficiency in at least one scripting/programming language (e.g., Bash, Python, Go, Rust).
• Familiarity with monitoring and logging stacks (Prometheus, Grafana, Loki, ELK,
OpenTelemetry).
• Bilingual proficiency in Mandarin and English is strongly preferred to support seamless communication with our global engineering and developer teams.
Nice-to-Have:
• Previous experience running blockchain infrastructure (Ethereum nodes, validators,sequencers, or similar).
• Understanding of EVM and blockchain scaling technologies.
• Exposure to distributed databases, consensus protocols, or high-throughput systems.
• Contributions to open-source DevOps, blockchain, or infrastructure tooling projects.
• Experience with security audits, penetration testing, or compliance frameworks.
