Responsibilities

- Design and deploy AI/LLM applications at scale (RAG, agentic systems, Q&A; platforms)

- Architect solutions using agentic frameworks, integrating with vector databases and advanced memory architectures

- Build APIs, data pipelines, and enterprise integrations (CRM, ERP, cloud platforms)

- Evaluate and refine AI performance using LLM-based evaluation, agent metrics, and A/B testing

- Ensure performance, security, observability, and cost-efficiency across deployed solutions

- Conduct research, rapid prototyping, and experimentation to validate feasibility and business value

- Stay current with emerging AI protocols (MCP, A2A, ACP) and evolving LLM technologies

Requirements





- 5+ years in AI/ML engineering with production-grade delivery experience

- Strong Proficiency in at least one modern programming language and web frameworks (Python, Java, Scala)

- Hands-on experience with major LLM platforms, agentic frameworks, and advanced integration patterns (RAG, agent orchestration, tool calling)

- Experience with vector databases, semantic/hybrid search, and retrieval/ranking systems

- Knowledge of MLOps/AIOps practices, monitoring, and security (including prompt injection prevention)

- Strong communication skills — able to translate complex AI concepts for both technical and non-technical audiences
