Senior Platform Engineer (Java & Python)
Primary stack
Job description
About the Role
Intempt processes 350M+ events/month across a unified Customer Data Platform, analytics, and ML stack. The core works. We need someone to make it bulletproof at scale.
You'll own the infrastructure that powers real-time personalization, journeys, and decisioning models. Java for the platform services, Python for the ML and data pipelines. This is platform engineering - not application development.
Responsibilities
- 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
- Python data pipelines - ML serving, embedding jobs, batch processing
- System reliability, observability, and incident response
You Are
- 5+ years deep in Java and Python 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
Tech Stack
- Java 21
- Python
- Spring Boot WebFlux
- FastAPI
- Kafka
- Apache Flink
- ClickHouse
- PostgreSQL
- Neo4j
- Redis
- Kubernetes
- AWS
Not a Fit If
- You need clean requirements to get started
- You think "it works at small scale" closes a ticket
