Lead code reviews, establish engineering best practices, and drive a culture of quality and ownership.
Formulate data management strategies across SQL/NoSQL databases (PostgreSQL, MySQL, Oracle, MongoDB, Redis) including caching and performance tuning.
Recommend and evaluate emerging backend technologies, frameworks, and patterns to continuously improve system capabilities.
Control system reliability, availability, and security posture through proactive monitoring, incident management, and root cause analysis.
Synergize across Product, Frontend, DevOps, and QA teams to align technical delivery with business goals.
Use AI-assisted development tools thoughtfully to improve backend delivery, test coverage, debugging, and documentation without compromising quality or security.
Mentor mid and junior engineers, fostering technical growth and engineering culture within the team.
Evaluate and manage technical debt, dependency lifecycle, and long-term platform scalability.

Mid

Develop and maintain backend services and RESTful APIs using Golang, Java Spring Boot, or Python, with a focus on scalability and performance.
Implement and manage SQL/NoSQL database schemas (PostgreSQL, MySQL, Oracle, MongoDB, Redis) and apply caching strategies.
Build and maintain microservices following established architecture patterns and engineering standards.
Collaborate with Product Managers, Frontend Engineers, and QA to deliver end-to-end features and seamless integrations.
Plan and contribute to CI/CD pipelines and containerized deployments using Docker & Kubernetes.
Write clean, testable, and well-documented code in alignment with team coding standards.
Participate in code reviews and recommend improvements to development processes.
Use AI-assisted coding tools where appropriate for implementation, debugging, tests, and documentation, validating all output through established engineering practices.
Troubleshoot and resolve backend performance issues, API failures, and database bottlenecks.
Evaluate and implement caching, queuing, and optimization techniques under team guidance.
Maintain technical documentation for services, APIs, and system components.
Stay current with backend ecosystem trends and contribute learnings to the team.
