Sr. Manager, Site Reliability & Innovation, IT

Take ownership of SRE practices, Kubernetes platform reliability, and system monitoring to maintain optimal uptime, resilience, and operational performance.

Architect, upgrade, and maintain enterprise observability solutions powered by ITRS Geneos, Prometheus, Victoria-Metrics, Elasticsearch, and Grafana.

Design, refine, and maintain alerting policies, analytical dashboards, and telemetric data pipelines.

Administer RHEL Linux server fleets (versions 7, 8, and 9) through patching, configuration, OS upgrades, and system troubleshooting, ensuring monitoring strategies align with infrastructure modifications.

Perform log analysis, root cause investigations, and fault isolation to resolve performance bottlenecks.

Partner with development, software engineering, and core infrastructure units to elevate system stability, efficiency, security, and scalability.

Manage, optimize, and maintain Kubernetes cluster health, workload orchestration, capacity management, and container observability.

Evaluate, test, and integrate modern SRE frameworks, observability tools, and operational methodologies.

Requirements

Bachelor's degree or higher in Computer Science, Software Engineering, or a related field.

Approximately 8 to 10 years of experience in IT operations, with a emphasis on site reliability engineering, platform engineering, production support, or investment banking systems.

Proven expertise in implementing and supporting enterprise monitoring and observability suites (ITRS Geneos, Prometheus, Victoria-Metrics, Elasticsearch, Grafana, Kibana).

Demonstrated proficiency in automation scripting using Bash, Python, Ansible, and CI/CD automation platforms.

Practical experience building Prometheus telemetry pipelines, including custom exporters, scrapers, metric relabeling, and long-term storage integrations like Victoria-Metrics.

Hands-on experience constructing Logstash processing pipelines for log ingestion, parsing, filtering, and routing into Elasticsearch.

Proven track record of designing Grafana and Kibana visualization dashboards for metrics, logging, and system performance telemetry.

Deep understanding of observability concepts, metric aggregation, log enrichment, and alerting architectures.

Strong Red Hat Enterprise Linux administration skills (RHEL 7/8/9), covering kernel/system tuning, patching, configuration management, and issue resolution.

Solid grasp of core SRE principles, high availability architectures, capacity planning, incident management, and Business Continuity / Disaster Recovery procedures.

Experience managing GPU-powered infrastructure for artificial intelligence or machine learning applications is preferred.

Direct expertise in Kubernetes administration, cluster operations, pod scaling, workload management, and production troubleshooting.

Foundational knowledge of network protocols, performance tuning, and distributed systems architecture.

Willingness to join on-call rotations, providing after-hours and weekend operational coverage.

Self-starter mindset with strong adaptability, continuous learning drive, and time management skills.

Fluent in English, with knowledge of Chinese considered a beneficial asset.

This position is offered through a strategic partnership between Don Nelson Technology Limited and NP Solution Limited.
