Monitor and optimize performance, scalability, reliability, and cost efficiency of distributed data processing workloads.

Develop reusable frameworks, libraries, templates, and engineering patterns that improve development productivity and consistency.

Implement and support CI/CD pipelines, Infrastructure-as-Code principles, and deployment automation for data engineering solutions.

Troubleshoot complex data integration, performance, and operational issues across platforms and pipelines.

Collaborate with platform, infrastructure, architecture, and security teams to build resilient, scalable, and secure enterprise data solutions.

Create and maintain technical documentation, architecture diagrams, operational runbooks, and implementation guides.

Participate in technical design sessions, architecture reviews, and engineering discussions while providing recommendations and solutions.

Mentor and guide junior and mid-level data engineers through technical coaching, code reviews, design reviews, and knowledge sharing.

Evaluate and adopt emerging technologies, engineering practices, and AI-assisted development capabilities to improve delivery velocity and quality.

Support production operations through monitoring, root cause analysis, incident resolution, and continuous improvement initiatives.

Contribute to Agile delivery processes including sprint planning, estimation, backlog refinement, and execution of engineering commitments.

Promote DataOps practices, automation, observability, and engineering excellence across development teams.
