Job Category: Advanced AI & ML

Job Description:

Key Responsibilities

- Design and develop LLM-based solutions for business use cases (e.g., chatbots, summarisation, document intelligence).
- Build and optimise RAG (Retrieval Augmented Generation) pipelines including data ingestion, embeddings, and retrieval.
- Implement prompt engineering techniques (prompt design, chaining, optimisation).
- Develop backend services/APIs for AI applications using Python frameworks (FastAPI / Flask / Streamlit).
- Integrate LLM solutions with enterprise systems and structured/unstructured data sources.
- Apply basic guardrails and evaluation techniques to improve response quality and reduce hallucinations.
- Collaborate with cross-functional teams to ensure data quality, model performance, and deployment readiness.
- Document solutions and contribute to reusable components and best practices.

Must-Have Skills

Experience

- 0-4 years total experience, with exposure to AI/ML, NLP, or Data Engineering projects
- Hands-on experience or strong learning exposure to LLM / GenAI use cases (projects, POCs, academic work, or professional)

LLM / GenAI & Agentic Engineering
- Strong hands-on experience with:

- LLMs (Claude, OpenAI, etc.)
- RAG pipelines and retrieval optimisation
- GPT + Agentic AI implementation experience
- Experience with:

- LangChain, LangGraph, or similar frameworks
- Agent orchestration and tool-calling architectures
- Deep understanding of:

- LLM limitations, evaluation, and optimisation strategies

Core Engineering
- Strong Python/Pyspark engineering expertise (production-grade development) with proven API integration experience
- Deep data analysis experience and handling large volume of data




- Fabric/Azure Databricks/Snowflake data engineering integration skills
- Valuable exposure to:

- Cloud platforms (Azure/AWS/GCP)
- SQL
- Containers, CI/CD, monitoring

Good-to-Have

- Exposure to agentic workflows or tool calling concepts
- Basic knowledge of fine-tuning / prompt tuning (LoRA, PEFT - optional exposure)
- Experience with Azure OpenAI / Azure AI Search or similar stacks
- Awareness of enterprise AI considerations (data security, privacy, governance)
