We are looking for a highly experienced and technically strong Senior Java Developer who brings a unique blend of architectural thinking and hands-on coding expertise. This role is ideal for candidates who are passionate about high-performance backend systems, microservices architecture, and writing clean, optimized code using modern Java, Spring Boot, and associated cloud-native technologies.

As a key individual contributor, you will be responsible for end-to-end technical ownership — from architecture and design decisions to core backend development and performance optimization in large-scale distributed systems.

• Write high-performance code applying advanced data structures and algorithms for real-world large data challenges.


• Design and implement caching strategies and low-latency data pipelines using Redis.


• Develop and deploy containerized services using Docker and orchestrate them via Kubernetes.


• Lead the technical direction on projects including system design, database schema design, and performance tuning.


• Collaborate with product teams and other engineers to convert product requirements into scalable, production-ready solutions.


• Conduct thorough code reviews, enforce best coding practices, and mentor junior developers where applicable (without people management responsibilities).

______________

Required Skills:


• Strong core Java (8/11/17) development experience with advanced knowledge of the JVM.


• In-depth understanding of data structures and algorithms and their application in backend development.


• Expertise in Spring Boot, Spring Cloud, and building production-grade microservices.


• Practical experience in system architecture, design patterns (Factory, Singleton, Observer, etc.), and architectural principles (SOLID, DDD).


• Hands-on experience with Redis for caching and performance optimization.


• Proficiency in Docker and deploying applications on Kubernetes clusters.


• Strong database skills: experience with both SQL (PostgreSQL/MySQL) and familiarity with NoSQL solutions.


• Exposure to distributed systems, message brokers (Kafka/RabbitMQ), and event-driven architecture.


• Experience working in high-throughput, low-latency environments with a focus on performance tuning.


• Proven ability to work independently in a fast-paced environment and take technical ownership of features and modules.

______________

Preferred/Good to Have:


• Experience with cloud platforms (AWS, GCP, or Azure).


• Exposure to observability tools (Prometheus, Grafana, ELK Stack).


• Familiarity with CI/CD pipelines and DevOps best practices.


• Exposure to load testing and system resilience strategies (rate limiting, circuit breakers).
