You will work under architect guidance while owning key solution components, leading small workstreams, and delivering high-impact AI solutions across consulting engagements. The role requires a strong blend of software engineering, applied AI, optimization techniques, and secure development practices.

The ideal candidate demonstrates the ability to independently implement and optimize AI-driven systems, contribute to reusable accelerators, and mentor junior engineers while operating in a client-facing consulting environment.

Key Responsibilities:

• Design, develop, and optimize AI-driven automation solutions using LLMs, agent frameworks, and orchestration platforms.
• Own and deliver end-to-end implementation of solution components, including integration into enterprise systems and CI/CD pipelines.
• Optimize AI systems across dimensions such as latency, cost, accuracy, and scalability (e.g., caching, batching, prompt optimization).
• Develop and enhance Retrieval-Augmented Generation (RAG) pipelines, including chunking strategies, retrieval tuning, re-ranking, and embeddings optimization.
• Implement and optimize fine-tuning strategies, including dataset preparation, prompt tuning, and model evaluation workflows.
• Build and productionize agentic systems using frameworks such as LangGraph, AutoGen, CrewAI, Semantic Kernel, or equivalents.
• Develop automated evaluation frameworks, benchmarking pipelines, and model performance metrics.
• Contribute to AI harness frameworks, reusable accelerators, and enterprise AI development standards.
• Lead small workstreams, client discussions, demos, and proof-of-concept (POC) implementations.
• Mentor and review work of junior AI Automation Engineers, ensuring engineering quality and best practices.
• Collaborate closely with architects to translate high-level designs into scalable implementations.
• Ensure adherence to secure coding, DevSecOps, and AI security best practices.
