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

* Designing complex algorithms

* Building high-performance, memory-efficient systems

When we say "full-stack", we mean it. On a given day, you may need to work on anything from designing front-end components in React to provisioning backend Docker containers. If you’re not doing either of those, you’re probably creating micro-services in our distributed architecture. Have we covered enough topical (but true) buzz-words yet? Cool. Seriously, though, you’ll be working on software that’s re-defining how the Indian economy works. Who should join us: If any of the following apply to you, hit us up: ● You’d like to work on sophisticated distributed software that solves for complex financial workflows. ● You’re excited about the future of Digital India and want to work in a company that not only believes in that vision, but is also helping realise it. ● You want to work with fun folks who are also steeped in customer-driven product development. ● You like autonomy, and the freedom to come up with solutions that solve the problem best. Regardless of the technology. ● You believe in the power of data to solve previously unsolved problems. ● You’re secretly a great foosball player, looking for peers who can match your skills.
