Role Overview
We are looking for a hands-on Lead Engineer - AI to design, build, and deliver scalable AI-powered applications and platforms. The role requires strong engineering leadership, practical experience with LLMs, RAG, agents, prompt engineering, model integration, MLOps, APIs, and cloud-native deployment, along with the ability to mentor engineers and accelerate delivery using AI-assisted development tools.
Key Responsibilities

• Lead the design and development of AI/GenAI applications, LLM-powered workflows, agents, copilots, and intelligent automation solutions.
• Build production-grade solutions using Python, APIs, LLMs, vector databases, RAG pipelines, embeddings, and orchestration frameworks.
• Design and implement Retrieval-Augmented Generation, prompt engineering, function calling, tool use, context management, and evaluation workflows.
• Integrate AI capabilities with enterprise applications, APIs, databases, event-driven platforms, and business workflows.
• Define architecture patterns for AI solutions, including model selection, data flow, retrieval strategy, guardrails, observability, and cost optimization.
• Remain hands-on with coding, prototyping, debugging, code reviews, performance tuning, and production issue resolution.
• Establish engineering standards for AI solution development, including testing, evaluation, monitoring, security, privacy, and responsible AI controls.
• Mentor engineers and collaborate with architects, data scientists, ML engineers, product teams, security, DevOps, and business stakeholders.
• Use approved AI tools such as GitHub Copilot, Cursor, Microsoft Copilot, or equivalent to accelerate coding, testing, documentation, and solution design.
• Review and validate AI-generated code and model outputs to ensure correctness, explainability, security, and business alignment.

Required Skills And Experience

• 8+ years of software engineering experience, including experience in a technical leadership role.
• Strong hands-on experience with Python and backend/API development.
• Practical experience building AI/GenAI solutions using LLMs, RAG, embeddings, vector databases, prompt engineering, and agents.
• Experience with frameworks and platforms such as LangChain, LlamaIndex, Semantic Kernel, Azure OpenAI, OpenAI APIs, Hugging Face, or similar.
• Strong understanding of AI application architecture, model integration, data pipelines, and production deployment.
• Experience with vector databases such as Azure AI Search, Pinecone, Weaviate, Milvus, Chroma, or FAISS.
• Good understanding of MLOps/LLMOps concepts including model evaluation, versioning, monitoring, drift detection, feedback loops, and automated testing.
• Strong knowledge of REST APIs, microservices, cloud platforms, CI/CD, Docker, Kubernetes/OpenShift, and observability.
• Understanding of AI security, privacy, hallucination mitigation, prompt injection risks, access controls, and responsible AI principles.
