Principal Consulatant, Java

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
