About the Role:
We’re looking for a Site Reliability Engineer (SRE) to ensure the stability, performance, and reliability of our critical production systems. You’ll work at the intersection of development and operations — building automation tools, improving observability, and preventing incidents before they occur.

Key Responsibilities:

• Ensure the stability, performance, and fault tolerance of production systems.

• Develop and maintain infrastructure automation and observability tools.

• Monitor system health, respond to incidents, and perform root cause analysis (RCA).

• Collaborate with development teams to improve scalability and reliability of services.

• Define and manage SLIs, SLOs, and Error Budgets.

• Lead incident response: organize recovery, document RCA, and run blameless post-mortems.

• Configure and administer Grafana and Zabbix, design insightful dashboards, and fine-tune alerting.

• Integrate and monitor external vendor systems, collaborating with vendor technical support when needed.
