Job description

• 3+ years of production Kubernetes experience; bare-metal / on-premises. Experience is mandatory — cloud‑managed Kubernetes experience alone does not qualify.
• Hands‑on Helm chart authoring (not just consumption), ArgoCD or equivalent GitOps tooling, and cert‑manager.
• Deep understanding of Kubernetes control plane HA: etcd Raft quorum, leader election.
• Experience with MetalLB and Traefik or equivalent bare‑metal ingress and load balancing tools.

Messaging & Streaming

• Production hands‑on experience with Apache Kafka: topic configuration, partition.
• Solid understanding of consumer lag monitoring and back‑pressure patterns under burst load.
• Strong familiarity with MQTT protocol semantics: persistent sessions, QoS levels, TLS mutual authentication; hands‑on experience with EMQX or a comparable broker at tens‑of‑thousands of concurrent connections.

Data Infrastructure

• Production hands‑on experience with PostgreSQL HA: Patroni‑based automatic failover, PgBouncer connection pooling, streaming replication, PITR with pgBackRest or equivalent.
• Working knowledge of Valkey / Redis: cluster mode, TTL‑based caching, atomic counter operations.

Observability

• Hands‑on deployment and configuration of VictoriaMetrics / Prometheus, Grafana, Loki, Tempo, and Alertmanager.
• Ability to write PromQL / MetricsQL queries and author production Grafana dashboards from scratch.
• Experience configuring alert deduplication and grouping in Alertmanager for high availability.

Security & Secrets

• Hands‑on experience with HashiCorp Vault / OpenBao: PKI secrets engine, Kubernetes auth method, dynamic secrets.
• Experience with container image CVE scanning (Trivy or equivalent) and a self‑hosted container registry (Harbor or equivalent).
• Understanding of TLS certificate lifecycle management: internal CA, automated.

CI/CD & GitOps

• Experience building CI pipelines with real service dependency testing (testcontainers‑go or equivalent).
• GitOps workflow discipline: Git as the sole source of cluster state truth, PR‑gated deployment approvals.

Programming

• Go (Golang): able to read, debug, and modify existing microservice code — trace latency issues through service logic, adjust Kafka consumer configuration, update retry semantics; authoring new services from scratch is not required.
• Bash scripting for automation and operational runbooks.
• Strong proficiency with YAML / TOML for Kubernetes manifests, Helm values, and service configuration.

Networking

• Understanding of TCP/TLS at scale: TLS handshake cost, session resumption overhead, connection state memory at 30,000 simultaneous connections.
• Working knowledge of data centre networking concepts (MLAG, VLAN, MTU, ToR design); able to collaborate effectively with a dedicated networking team.

Preferred Qualifications

• BS degree in Computer Science or Engineering or equivalent experience.
