This Is NOT a Typical Java Role If your experience is mostly CRUD APIs, controller wiring, or shallow service layers — this role is not for you. We are looking for a top tier backend engineer who thrives on:
* Designing complex algorithms
* Building high-performance, memory-efficient systems
* Owning deep backend logic that actually moves the needle
You will work close to the core engine of the product, not the edges.
What You’ll Be Trusted With
* Architect and build backend systems that must perform under load
* Design and implement custom algorithms for real-world, non-trivial problems
* Solve performance bottlenecks involving CPU, memory, I/O, and concurrency
* Build backend services where latency, throughput, and correctness matter
* Own document & PDF processing pipelines end-to-end:
-Composition
-Rendering
-Optimization
- High-volume generation
* Make hard technical decisions and stand by them
Non-Negotiable Skills
* Exceptional Java expertise (Core Java, Spring Boot, Java 8+)
* Strong command over:
- Data structures & algorithms
- Multithreading & concurrency models
- JVM internals & memory management
* Proven experience building custom algorithms (this will be evaluated)
* Deep backend engineering experience with Spring / Spring Boot
* Strong understanding of:
- API design principles
- Fault tolerance & resilience
- Performance tuning & profiling
* Ability to reason about time complexity, space complexity, and trade-offs
* Strong database fundamentals (query optimization, indexing, transactions)
* Experience with message brokers (ActiveMQ, Kafka, RabbitMQ)
* Exposure to Kubernetes-based deployments or large-scale microservices
Interview Focus (Be Prepared)
* Algorithm design & problem solving
* Deep Java fundamentals
* System design discussions (backend-heavy)
* Performance tuning scenarios
* Real-world debugging and optimization challenges
