2) Real-world experience with high-TPS, large-scale systems (or a burning desire to master them).
4) Exposure to AWS Cloud Infrastructure and cloud-native patterns.
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
