Monitoring Tools and Metrics Analysis :

- Proficient in using monitoring tools such as Grafana, Prometheus, and Loki for real-time system monitoring and alerting.

- Experience with analyzing and troubleshooting system performance metrics and logs.

Incident Management and Root Cause Analysis :

- Proven experience in managing incidents, conducting post-mortems, and implementing measures to prevent future incidents.

CI/CD and Automation :

- Hands-on experience with CI/CD tools like Jenkins, GitLab CI, or CircleCI for automating deployments.

- Ability to write automation scripts in languages like Python, Bash, or Ruby to streamline operational workflows.

Performance Testing :

- Expertise in using performance testing tools like Gatling and JMeter to assess system scalability and performance under load.

Collaboration and Documentation Skills :

- Excellent interpersonal skills with the ability to work collaboratively in cross-functional teams.

- Strong technical writing skills for documenting complex systems and processes.

Preferred Qualifications :

- Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent work experience).

- Certifications in relevant technologies (e.g., AWS Certified Solutions Architect, Kubernetes Administrator, Red Hat Certified Engineer).

- Experience with distributed systems, container orchestration (e.g., Kubernetes), and microservices architecture.
