Familiarity with vector databases and embedding stores.

2+ years building or operating ML / LLM-powered applications in production.

5+ years leading cross-functional architecture and mentoring senior engineers.

Expertise in Kubernetes, Helm / Kustomize, GitOps (Argo CD / Flux), service mesh (Istio / Linkerd), autoscaling, security, and cost optimization.

Proficiency with CI / CD tools like Jenkins (or equivalent), Terraform / CloudFormation, blue-green / canary deployments, feature flags, automated testing, and rollback strategies.

Skilled in REST and GraphQL API design, secure service-to-service authentication, rate limiting, quotas, and event streaming (Kafka / Pub / Sub).

Experience with observability tools such as Prometheus, Grafana, tracing, metrics, log aggregation, SLOs, error budgets, and incident response.
