DevOps Engineer

About the Role

Operate and build the platform for our multi-cloud infrastructure and container clusters, including our self-hosted E2B (AI agent sandbox) cluster, and keep production services highly available, scalable, and cost-efficient through automation and platform engineering.

Responsibilities

Cluster Operations & Management Manage and maintain container clusters (Kubernetes, Docker) and open-source middleware clusters (Kafka, Redis, Elasticsearch) across multiple business units. Own the self-hosted E2B (AI agent sandbox) cluster, including the Nomad / Consul orchestration layer and the Firecracker microVM runtime.

Ensure the performance, scalability, and reliability of distributed systems. Linux & Cloud Infrastructure Handle day-to-day operations of Linux servers, including hardening, patch management, backups, and performance tuning. Manage cloud resources across AWS, Azure, and GCP, ensuring reliability, security, and cost efficiency.

Infrastructure Platform Development Design, build, and continuously improve our infrastructure operations platform. Develop and maintain infrastructure management, CI/CD Git. Ops pipelines (Jenkins / Argo CD), monitoring and alerting (Prometheus / Grafana), and centralized logging (ELK). Drive platform standardization and automation.

High Availability & Reliability Ensure the highest availability of production services through proactive monitoring and incident response. Take part in a 24/7 on-call rotation, and lead incident response, root cause analysis, and postmortems. Implement and maintain SLA/SLO frameworks and reliability engineering practices.

Automation & Process Improvement Build self-service tools and workflows to improve team productivity. Establish best practices for infrastructure as code (Terraform / Ansible) and configuration management. Maintain thorough documentation, SOPs, and runbooks.

Requirements

3–4+ years of hands-on experience in Linux system operations, DevOps, or SRE (no degree requirement; ability comes first). Strong Linux fundamentals, with knowledge of networking basics and system security best practices. Deep expertise in containerization (Kubernetes, Docker), with experience operating production-grade clusters.

Experience building and managing CI/CD pipelines (Jenkins, GitHub Actions / Argo CD). Familiarity with common infrastructure components: Nginx, MySQL, Redis, Kafka, and Elasticsearch. Proficiency in Shell and Python for scripting and automation. Hands-on operations experience with at least two public clouds among AWS, Azure, and GCP.

Familiarity with infrastructure monitoring, logging, and observability tools (Prometheus, Grafana, ELK). Hands-on experience with Terraform. Ability to collaborate on technical work in Mandarin and to read, write and participate in day-to-day technical communication in English.

Preferred Qualifications

Familiarity with or exposure to E2B / AI agent sandbox infrastructure (Firecracker microVM, Nomad, Consul). Experience with service mesh architecture (Istio) and eBPF. CKA/CKAD or AWS/Azure/GCP professional certifications.
