• Deep understanding of concurrency, data replication, idempotency, partial failure modes, and eventual consistency.
• Proven track record of leading technical design reviews, author clear RFCs/design docs, and mentor engineering teams.
• Excellent verbal and written communication skills in English, with experience collaborating across cross-functional engineering teams.

Preferred Qualifications

• Hands-on experience scaling and running stateful workloads in Kubernetes (PostgreSQL, distributed NoSQL databases, caching layers, or object storage).
• Experience with Infrastructure as Code (Terraform), CI/CD pipelines (GitLab/Jenkins), and service mesh/networking infrastructure (load balancers, API gateways, DNS, TLS).
• Practical knowledge of SRE standards, distributed tracing, alerting frameworks, and chaos/recovery testing.
