  • Ensure data quality, reliability, scalability, and performance.
  • Support AI memory systems, knowledge retrieval mechanisms, and data synchronisation processes.

Engineering Excellence

  • Leverage AI-assisted development tools as part of daily engineering workflows.
  • Implement CI/CD pipelines, automated testing, monitoring, and observability practices.
  • Participate in code reviews and contribute to engineering best practices.
  • Maintain high standards for security, documentation, testing, and software quality.
