What you will be working on

Agentic Web Application Development

Implement robust, scalable applications that enable autonomous AI agents using AI Frameworks (e.g. LangGraph ) for complex multi-step reasoning and decision-making workflows. Build responsive, user-friendly interfaces that allow users to interact with, monitor, and control AI agents performing complex tasks and workflows.

Search & Retrieval Development

Implement web services and APIs that enable efficient search and retrieval of information from large-scale data repositories ( e.g. Elastic / Redis) using hybrid search capabilities. Build data ingestion pipelines and vector indexing workflows that support real-time query processing and document retrieval. Develop robust error handling and fallback mechanisms for search service integration, including query reformulation and result ranking optimisation.

User Interface & Experience Implementation

Build intuitive web interfaces that enable MAS officers to interact with complex AI systems with lower learning curve . Implement dashboards, configuration panels, and monitoring interfaces that provide clear visibility into AI application performance and behaviour.

Performance Optimisation & Scalability

Implement performance optimisations for web applications handling AI workloads. Build caching mechanisms, request queuing systems, and load balancing solutions that ensure responsive user experiences even under heavy AI processing loads.
