• Architect and implement event-driven systems (Kafka, RabbitMQ, pub/sub).
• Develop secure and reliable financial systems with strong data integrity.
• Solve scalability and performance challenges in fintech/crypto environments.
• Own features end-to-end: design → development → deployment → monitoring.
• Work with real-time data pipelines (WebSockets, streaming, event sourcing).
• Define service contracts and optimize system architecture.

AI-First Engineering (Must-Have Mindset) :

You will :

• Use tools like GitHub Copilot, Cursor, and Claude in daily development
• Follow spec-driven development using structured instructions
• Review, validate, and ship AI-generated code with strong engineering judgment

Core Requirements :

• 3+ years of backend development experience.
• Strong expertise in Java (Spring Boot) or Node.js.
• Solid understanding of System Design (HLD/LLD, Distributed Systems).
• Experience with event-driven architectures (Kafka, RabbitMQ, async pipelines).
• Hands-on experience building low-latency, high-throughput systems.
• Strong database knowledge (PostgreSQL, MongoDB, etc.).
• Understanding of security, performance optimization, and reliability.
• Experience with CI/CD, Git, Docker, Kubernetes.
• Exposure to React / React Native is a plus.

Good to Have (Differentiators) :

• Experience in FinTech / Crypto / Web3 / Blockchain.
• Built systems for trading, payments, or real-time financial data.
• Experience with AI agents, automation pipelines, or agent-based systems.
• Exposure to parallel AI workflows (coding / testing / refactoring).
• Contributions to open source or technical blogs.
• Experience handling production-scale systems.
