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.

Requirements:

• 2-5 years of hands-on backend engineering experience.
• Technology Stack: Java, Spring Boot, Multithreading, REST APIs, AWS.
• Strong Java fundamentals (Java 11+): collections, generics, streams, memory model.
• Solid experience with Spring Boot and the Spring ecosystem.
• Real understanding of multi-threading and concurrency: thread pools, executors, race conditions, locks.
• Comfortable with SQL and relational databases (Postgres or MySQL preferred).
• REST API design fundamentals; Git and modern developer workflows.
• Strong data structures and algorithms base you can reason about time and space.
• Ownership mindset and a willingness to ship, learn, and iterate.
