Backend - Software Engineer About US: Paytm is India’s largest digital payments and financial services platform, leading the mobile QR revolution. We power millions of businesses and individuals, and we’re building scalable, resilient systems to serve half a billion Indians and beyond. Here at Paytm, technology isn't just about keeping up, it's about building the future. We believe the next generation of engineers must not only scale systems to billions but also leverage AI and GPT tools to accelerate innovation. About the role: 1) You will design, build, scale, code, and optimize systems that operate at massive transaction volumes (120 million transactions per day). 2) You’ll go deep into systems thinking, microservices, caching, messaging, and scalable data architectures. 3) You’ll also be encouraged to actively use AI tools (like GPT and others) in your development workflow to code faster, smarter, and better. What We're Looking For: 1) 1+ years of backend development experience in Java. 2) Real-world experience with high-TPS, large-scale systems (or a burning desire to master them). 3) Hands-on with Kafka, Redis, RDBMS, and distributed microservices architectures. 4) Exposure to AWS Cloud Infrastructure and cloud-native patterns. 5) Passion for scaling, performance tuning, and system optimizations. 6) Someone who loves to experiment with AI tools (like GPT, Copilot, OpenHands) for code generation, optimization, or workflow improvement. 7) You love writing clean, efficient, production-ready code — but you are even more obsessed with system performance, uptime, and user impact. Preferred Qualifications : Bachelor's/Master's Degree in Computer Science or equivalent Skills that Will Help You Succeed: 1) Languages: Java / Node.js 2) Databases: Postgres, MySQL, CASSANDRA 3) Messaging Systems: Kafka, RabbitMQ 4) Caching: Redis, Aerospike 5) Platforms: AWS, Microservices 4) Monitoring : Elastic Search, Kibana, Graphana 5) Obsessed with low latency, high thro
