Backend Engineer

Responsibilities:
Design and build backend services in Java and Spring Boot, clean, testable, and production-ready code that runs at scale.
Own multi-threaded and concurrent workflows for real-time data ingestion, event processing, and low-latency inference pipelines.
Design and ship REST APIs used by our frontend, mobile, and integration partners with a strong sense for versioning, error handling, and documentation.
Model and query data in relational (Postgres/MySQL) and NoSQL stores; write efficient queries, design schemas that don't come back to haunt you.
Integrate with ML services and streaming systems (Kafka / message queues) to serve model outputs to plant operators in real time.
Debug production issues on live customer deployments, trace the problem, ship the fix, prevent the recurrence.
Contribute to system design conversations; you'll have a voice in architecture decisions, not just tickets to close.
Write tests and review unit, integration, and thoughtful code reviews for teammates. We take engineering hygiene seriously.
