Key Responsibilities

• Responsible for operation and maintenance related platform design and development work; participate in the construction and continuous improvement of the operation & maintenance system.
• Participate in the daily management, operation and maintenance of platform systems, ensuring stability, performance, and security.
• Research service architecture, discover potential problems, formulate system adjustment and optimization plans to improve system stability, efficiency, and security posture.
• Build, deploy and maintain internal tooling and backend services to monitor on-chain and off-chain activity.
• Develop alerting systems and dashboards to track the health of blockchain transactions, internal services, and third-party APIs.
• Work closely with developers to build observability and reliability tooling (logging, tracing, metrics, profiling) and integrate security signals into existing monitoring.
• Embed security into the CI/CD pipeline, including image scanning, dependency scanning, SCA, SAST/DAST integration, and enforcing security gates for critical services.
• Design and implement secrets management and key management best practices, including KMS/HSM integration, key rotation, access control, and secure handling of credentials, API keys, and certificates.
• Harden infrastructure and runtime environments, including Kubernetes, containers, Linux hosts, and cloud accounts (AWS/GCP), following least-privilege, network segmentation, and baseline hardening standards.
• Collaborate with Security / Compliance / Custody teams to translate policies (e.g. access control, segregation of duties, audit logging) into technical controls and automation.
• Participate in incident response and post-incident review, including triage, log analysis, impact assessment, and implementing long-term preventive measures via automation.
• Continuously improve security observability, including anomaly detection on privileged operations, configuration drift, and blockchain-related risk signals.
• Perform other related duties as assigned based on evolving operational and security needs.

Requirements

• Bachelor’s degree or above with minimum 3 years DevOps / SRE / Platform Engineering experience; strong computer science or related background.
• Solid experience with Linux, Docker, shell scripting, databases, CI/CD tools, Git, and common deployment/maintenance/optimization practices.
• Hands-on experience with AWS services (EC2, RDS, S3, EKS, ECR, etc.); familiarity with Google Cloud or other major cloud providers.
• Understanding of Kubernetes or other orchestration frameworks; experience with cluster hardening, RBAC design, and policy engines is a plus.
• Familiar with container technologies and underlying OS concepts (filesystem, namespaces, cgroups); Docker internals or source code familiarity is a strong plus.
• Backend development experience (e.g. Java, Go, Node.js, Python) for building internal tools, automation, and integrations.
• Practical experience in at least some of the following DevSecOps areas:
• Integrating security tools into CI/CD (image scanning, dependency scanning, IaC scanning).
• Secrets management (Vault/KMS/Secrets Manager etc.).
• Infrastructure as Code (Terraform/CloudFormation) with security best practices.
• System and network hardening, firewall / security group management, zero-trust / least-privilege design.
• Centralized logging, SIEM, or security analytics for production systems.
• Familiarity with security frameworks or concepts, such as OWASP Top 10, CIS Benchmarks, principle of least privilege, secure key management; experience in regulated / financial / crypto environments is a plus.
• Strong communication and collaboration skills, able to work closely with developers, security, and operations teams to land secure-by-design solutions.
• Able to articulate thoughts, risks, and trade-offs in a respectful and constructive manner.
• Ability to work independently and as a team player, with a strong sense of ownership, responsibility, and attention to detail.
• Comfortable in a fast-paced, high-availability, security-sensitive environment.
