* 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
