Quick Facts

• Role: Senior AI Engineer

Description

Build evaluation-driven, secure, and scalable agentic systems. Architect multi-agent workflows, engineer robust tool interfaces, and implement Retrieval-Augmented Generation (RAG) systems grounded in proprietary data. Create evaluation pipelines and production guardrails, and ensure AI outputs are structured for rich UI rendering.

Responsibilities

• Architect, build, and orchestrate complex multi-agent workflows with LangGraph and LangChain
• Define and maintain tool interfaces to interact with internal APIs (parse, validate, and use data)
• Build and optimize RAG systems for grounding model responses in proprietary data
• Structure AI responses for rich UI rendering (dynamic graphs, charts, and interactive elements)
• Create testing frameworks, evaluation pipelines, and metrics to measure agent performance, reliability, and accuracy
• Bring validated prototypes to production readiness, covering guardrails, security, cost, and scale
• Debug and optimize multi-agent workflows with focus on async execution, state management, and concurrency
• Deploy and maintain production-grade AI applications with a DevOps mindset

Requirements

• 3+ years of relevant experience in AI Engineering or a related field
• Proficiency in Python and the modern AI engineering stack
• Expertise in LangChain, LangGraph, and OpenAI SDK
• Familiarity with Hugging Face Transformers and multi-agent workflow optimization
• Skills in asynchronous execution, state management, and concurrency
• Background in designing and integrating with complex REST and GraphQL endpoints
• Competency in handling structured data formats (JSON, XML) for tool calling
• Hands-on experience with Docker
• Knowledge of cloud platforms such as AWS, GCP, or Azure
• Understanding of vector databases (Pinecone, Weaviate, Chroma) and embedding strategies for semantic search and RAG
• English proficiency at Upper-Intermediate level (B2) or higher
