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.
Key Requirements:
Fluent Russian, English B1+ (comfortable with technical documentation).
3+ years of experience as an SRE, DevOps, or Infrastructure Engineer.
Strong understanding of observability principles (metrics, logs, traces).
Hands-on experience with Grafana and Zabbix (administration, configuration, alert optimization).
Experience working with AWS and CI/CD tools.
Practical knowledge of SLI/SLO/Error Budget frameworks.
Experience leading and documenting incidents and post-mortems.
Scripting skills for automation (Python, Bash, or Go).
Solid understanding of distributed systems and networking fundamentals.

Experience monitoring and supporting mobile applications.
Familiarity with Terraform, Prometheus, Loki, ELK, or similar tools.
Experience working with Kubernetes and containerized environments.

Opportunity to work in an international team on a new digital product for the Mexican market.
A data-driven environment where your contributions have a real impact.
