Quick Facts

• Role: Senior AI Engineer

Description

You will build evaluation-driven, secure, and scalable agentic systems. The role focuses on architecting multi-agent workflows, engineering tool interfaces for complex internal APIs, and implementing RAG grounded in proprietary data. You will also create evaluation/testing pipelines and production-grade guardrails, security, cost, and scalability for reliable AI systems.

Responsibilities

• Architect, build, and orchestrate complex multi-agent workflows using LangGraph and LangChain

• Develop and maintain reliable tool definitions for internal API interactions

• Build and optimize RAG systems to ground model responses in proprietary data

• Ensure AI outputs are structured for rich UI rendering (dynamic graphs, charts, interactive elements)

• Create testing frameworks, evaluation pipelines, and production metrics for agent performance, reliability, and accuracy

• Move validated prototypes to production readiness with guardrails, security, cost, and scale

• Debug and optimize multi-agent workflows with asynchronous 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
