About Intempt Technologies
Intempt is an autonomous growth platform for online companies. It operates at billion-scale event volumes, powers real-time personalization and journeys, and embeds decisioning models directly into marketing, sales, design, analytics workflows.

We process 350M+ events/month across a unified Customer Data Platform (CDP), analytics, and ML stack. The core works. We need someone to make it bulletproof at scale.

What you'll own:

• High-throughput event ingestion and stream processing (Kafka, Flink)
• Low-latency query paths across ClickHouse, Postgres, and Neo4j
• JVM performance — GC tuning, heap profiling, hot path optimization
• Infrastructure stability under real load — not theoretical load

You are:

• 5+ years deep in Java backend systems — not just Spring CRUD, actual platform work
• Someone who has personally tuned a pipeline processing millions of events per hour
• Comfortable with distributed systems failure modes — partitions, back-pressure, replication lag
• The person who finds the bottleneck before the pager does

Stack you'll live in:
Java 21 · Spring Boot WebFlux · Kafka · Apache Flink · ClickHouse · Postgres · Neo4J · Redis · Kubernetes · AWS

Not a fit if:
You need clean requirements to get started, or you think "it works on small scale prod" and closes a ticket.

What we offer:
Competitive compensation · Ownership of real problems at web scale · No bureaucracy
