- Build Generative AI solutions, including conversational assistants, RAG applications, enterprise search, summarization, and intelligent workflow automation.
- Develop Agentic AI solutions using tool/function calling, orchestration, guardrails, human-in-the-loop controls, and auditable execution workflows.
- Integrate LLMs, ML models, REST APIs, vector databases, enterprise data sources, and existing applications.
- Develop scalable REST APIs and microservices using modern Python and Java frameworks.
- Implement prompt engineering, document chunking, embeddings, retrieval, reranking, grounded generation, and output validation.
- Design and implement AI evaluation frameworks covering accuracy, groundedness, safety, latency, reliability, and cost.
- Develop automated regression and testing frameworks for AI/LLM behavior and application functionality.
- Apply MLOps and LLMOps practices, including CI/CD, version control, containerization, model/prompt versioning, observability,



monitoring, and production support.
- Implement appropriate security, privacy, IAM, responsible AI, data governance, and model-risk controls for enterprise AI solutions.
- Collaborate with business and technical stakeholders to identify use cases, assess feasibility, define acceptance criteria, build prototypes, and transition solutions into production.
- Participate in architecture and design discussions and contribute to technical solution decisions.
- Perform code reviews, troubleshoot complex production issues, and ensure engineering best practices.
- Create and maintain technical documentation, architecture decisions, and operational runbooks.
- Mentor junior and intermediate engineers and contribute to continuous improvement of AI engineering practices.

Required Skills & Experience

- 8+ years of software engineering experience, with strong hands-on development in Python and Java.
- Proven experience building and deploying Generative AI / LLM-based applications in enterprise environments.
- Strong experience with RAG, embeddings, vector search, prompt engineering, document processing, retrieval, and response grounding.
- Hands-on experience developing Agentic AI applications, including tool/function calling, orchestration, workflows, guardrails, and human-in-the-loop patterns.
- Strong experience developing REST APIs, microservices, and cloud-native applications.
- Experience integrating LLMs, AI/ML models, APIs, enterprise data platforms, and third-party services.




- Experience with CI/CD, Git, Docker/containerization, automated testing, monitoring, and production support.
- Strong understanding of AI security, privacy, responsible AI, data governance, and enterprise application security.
- Experience working with cross-functional teams in Agile environments.
- Strong communication, problem-solving, and technical leadership skills.

Preferred Qualifications

- Experience with Azure AI, Azure OpenAI, Azure AI Search, or comparable cloud AI platforms.
- Experience with LangChain, Semantic Kernel, LlamaIndex, PyTorch, TensorFlow, or scikit-learn.
- Knowledge of Model Context Protocol (MCP), multi-agent architectures, agent orchestration, and enterprise knowledge platforms.
