Data & Integration

• Design and implement efficient data models for transactional and event-driven workloads.
• Work with both SQL and NoSQL databases to support high-throughput applications.
• Integrate with internal and external platforms through REST APIs, event streams, and third-party services.
• Optimize data access patterns and service interactions for performance and reliability.

Quality, Security & Observability

• Establish engineering best practices for testing, code quality, and deployment readiness.
• Implement logging, monitoring, tracing, and alerting strategies for production systems.
• Ensure secure API design through authentication, authorization, encryption, and industry-standard security practices.
• Drive adoption of observability and operational excellence across backend services.

Collaboration & Delivery

• Lead technical planning, estimation, and execution in Agile environments.
• Collaborate with product owners, architects, frontend teams, QA, and platform engineering teams.
• Support technical roadmaps and contribute to continuous improvement initiatives.
• Act as a technical leader for backend and API engineering efforts across multiple projects.

Required Qualifications
