Principal Java Engineer

As a Principal Java Engineer at our fast-growing start-up in the gaming industry, you will be responsible for leading the design and development of scalable backend systems that support live, data-intensive applications. This is a hybrid role based in Kolkata, offering an exciting opportunity for someone who thrives on solving technical challenges and wants to build great software in a dynamic and high-energy environment. Your key responsibilities will include designing and developing resilient backend systems using Java (17+) and Spring Boot, architecting APIs, microservices, and real-time backend components for gaming platforms, owning backend infrastructure, deployment pipelines, monitoring, and system performance, collaborating with product and delivery teams to translate ideas into production-ready features, and taking full ownership of backend architecture from planning to delivery and iteration. You will also be expected to continuously improve code quality, engineering practices, and overall system design. To succeed in this role, you should have 10-15 years of experience in backend engineering with strong expertise in Java (preferably 17+) and Spring Boot, proven experience in building high-performance, distributed systems at scale, hands-on experience with cloud platforms (AWS, GCP, or Azure), Docker, and Kubernetes, a strong understanding of SQL and NoSQL databases, caching (e.g., Redis), and messaging systems (Kafka, RabbitMQ), solid skills in debugging, performance tuning, and system optimization, and the ability to work independently, make pragmatic decisions, and collaborate in a hybrid team setup. It would be advantageous if you have experience in gaming, real-time platforms, or multiplayer systems, familiarity with Web Sockets, telemetry pipelines, or event-driven architecture, exposure to CI/CD pipelines, infrastructure as code, and observability tools. Joining us means working in a creative, fast-paced domain that blends engineering depth with product excitement, in a flat structure and high trust environment where the focus is on outcomes, not formalities. You will have a visible impact as everything you build will be used by real players in real time, and you will be part of an informal, collaborative culture where work is taken seriously, but not ourselves. Additionally, you will enjoy a flexible hybrid setup with 3 to 4 days a week in-office, allowing for focused work and team alignment. If you are passionate about solving hard problems and building something exciting from the ground up, we would love to hear from you.
