• Develop production-grade AI systems, ensuring scalability, reliability, security, and maintainability.
• Implement LLM-powered features, including prompt design, orchestration, structured outputs, and evaluation.
• Build agentic or multi-step AI workflows using modern AI frameworks (e.g. LangGraph, LangChain, or similar).
• Design and integrate search and retrieval systems, including data ingestion, vector indexing, and hybrid search.
• Develop backend services and APIs using Python-based frameworks (e.g. FastAPI, Django) and/or Node.js/Nest.js
• Build intuitive user-facing interfaces using modern frontend frameworks (e.g. React, Vue.js).
• Contribute to LLMOps / MLOps practices, including model versioning, evaluation, monitoring, and deployment workflows.
• Work with cloud infrastructure, containerisation, and CI/CD pipelines to deploy and operate AI systems.
• Balance speed and robustness appropriately across POCs, shared frameworks, and production systems.
• Collaborate closely with product managers, designers, other engineers and stakeholders to translate requirements into working solutions.
• Debug, monitor, and improve systems in production, upholding high standards of operational excellence.
