Industry: Real-time Systems / Technology

Employment Type: Full-Time

Compensation: Competitive, based on experience

About the Role:

We're a fast-growing startup in the gaming industry, building high-performance, real time platforms that power immersive digital experiences. We're looking for a Principal Java Engineer to lead the design and development of scalable backend systems that support live, data-intensive applications. This is a hybrid role based in Kolkata, ideal for someone who thrives on solving technical challenges, enjoys taking ownership, and wants to build great software in a dynamic, informal, and high-energy environment.

Key Responsibilities:

• Design and develop scalable, resilient backend systems using Java (17+) and Spring Boot
• Architect APIs, microservices, and real-time backend components for gaming platforms features
• Own backend infrastructure, deployment pipelines, monitoring, and system performance
• Collaborate with product and delivery teams to translate ideas into production ready
• Take full ownership of backend architecture — from planning to delivery and iteration
• Continuously improve code quality, engineering practices, and overall system design

Required Skills & Experience:

• 10–15 years of experience in backend engineering with strong expertise in Java (preferably 17+) and Spring Boot
• Proven experience building high-performance, distributed systems at scale
• Hands-on with cloud platforms (AWS, GCP, or Azure), Docker, and Kubernetes
• 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
• Ability to work independently, make pragmatic decisions, and collaborate in a hybrid team setup

Good to Have:

• Experience in gaming, real-time platforms, or multiplayer systems
• Familiarity with WebSocket, telemetry pipelines, or event-driven architecture
• Exposure to CI/CD pipelines, infrastructure as code, and observability tools

Why Join Us?

• Work in a creative, fast-paced domain that blends engineering depth with product excitement
• Flat structure and high trust — focus on outcomes, not formalities
• Visible impact — everything you build will be used by real players in real time
• Informal, collaborative culture — where we take our work seriously, but not ourselves
• Flexible hybrid setup — 3 to 4 days a week in-office, with room for focused work and team alignment
