Job description

We have partnered with our client in their search for a Senior Java 17 + ADX / KQL

Responsibilities

Java backend / event-driven processing

  • Implement Event Hub consumption patterns : consumer groups, partition awareness, batching, checkpointing strategy, retries / DLQ, idempotency.
  • Design and tune thread pools and scheduled work (e.g., backfills / replays / retries) with safe operational controls.
  • Build robust JSON parsing / validation, schema evolution handling, and error routing

ADX (Azure Data Explorer) + query performance

  • Write KQL queries for search / filter use cases and operational diagnostics.
  • Profile and tune ADX queries (query plan / diagnostics), reducing p95 latency and cost for hot queries.
  • Create clear query patterns and guardrails (parameterization, paging strategy, consistent query shapes).
  • API design : Search vs Retrieval

  • Define clean API contracts for search results : returned fields, filters, pagination semantics, error handling.
  • Implement retrieval "views" carefully (versioned, testable, limited scope) to avoid a server-side dumping ground.
  • Apply JWT authentication patterns and integrate with internal auth requirements.
  • Skills Required

  • Senior-level experience shipping and operating production backend services.
  • Java 17 : concurrency / thread pools, scheduled work, resilience patterns, profiling (CPU / GC / threading).
  • Event-driven systems (Event Hub / Kafka equivalents) : idempotency, retries / DLQ, replay / backfill safety.
  • ADX / KQL : proven ability to write and tune / profile queries (not just run them).
  • API design : production experience building search / filter endpoints and retrieval endpoints with stable contracts.
  • AKS / Kubernetes literacy : can deploy and debug your service (pods, logs, resources, probes, HPA basics).
  • Security basics : JWT validation / claims awareness; practical Managed Identity understanding for accessing Azure services.
  • Education & Work Experience

  • Bachelor's degree in equivalent field
  • Title Senior Java 17 + ADX / KQL
