Skills

Senior Backend Java 17 + ADX/KQL developer

Summary

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/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
