Responsibilities:

Backend Development

• Design, build, and maintain scalable, high-performance APIs using Python and Django

• Automate deployments using CI/CD pipelines (GitHub Actions, AWS CodeBuild, or similar)
• Apply infrastructure-as-code practices (Terraform, CloudFormation)
• Monitor, log, and troubleshoot distributed systems in production environments

AI-Driven Development

• Actively collaborate with AI coding assistants (Cursor, Windsurf, Copilot) to generate, refactor, and maintain production-quality code — aiming for at least 75% of development to be AI-assisted
• Design effective prompts, review AI outputs, and ensure generated code meets performance, scalability, and maintainability standards
• Focus on architecture, orchestration, and refinement of AI-generated code
• Continuously evolve internal best practices for human-AI collaboration

Collaboration & Quality
