• Experience with monitoring tools, especially Prometheus and Grafana
• Exposure to centralized logging platforms such as the ELK Stack (Elasticsearch, Logstash, Kibana)

We’re also looking for

• Experience with Terraform for cloud infrastructure provisioning

What we can offer you

• A chance to be part of a company specializing in artificial intelligence, where you’ll work on real products with real impact.

• Freedom to try new ideas and build your own solutions, in a culture where failing fast is fine as long as we learn from it.
• Flexible/hybrid working style with the option to work from our İstanbul or Ankara office.
• Private health insurance, meal card, and transportation allowance.
