• Implement data preprocessing pipelines and feature engineering workflows
• Ensure codebases are secure, scalable, maintainable, and aligned with software engineering best practices
• Monitor deployed models and services, iterating based on performance metrics, feedback, and evolving requirements
• Maintain clear documentation and appropriate testing coverage for all developed components
• Contribute to shared design, development, deployment, and monitoring practices within cross-functional agile teams

Requirements:
• Strong proficiency in Python, including object-oriented and functional programming
• Solid experience building API-driven services using FastAPI or Flask

• Experience with model deployment and serialisation (e.g. Joblib, Pickle, TorchScript)
• Hands-on experience with LangChain and other open-source frameworks for AI agents and orchestration pipelines
• Strong software engineering fundamentals, including Git-based version control and testing with Unittest or Pytest
• Understanding of API security practices, including authentication and input validation
• Experience working with Azure cloud platforms and Docker-based containerisation
• Ability to work effectively in agile environments
• Strong communication skills and the ability to collaborate with cross-functional teams

Nice to Have:
• Experience working closely with stakeholders to shape and refine AI-powered solutions
• Demonstrated ability to adapt to changing requirements and iterate on deployed services based on real-world feedback
• A continuous improvement mindset, focused on improving reliability, scalability, governance, and maintainability
• Experience managing AI services end to end, including deployment, monitoring, documentation, and ongoing support
• A future-focused approach to building scalable, secure services aligned with long-term platform needs
