Job Description

Day-to-day

• Lead the design and development of an enterprise AI platform that enables agentic workflows across structured and unstructured data. This hands-on role combines software development, platform architecture, AI strategy, and technical leadership to build scalable AI solutions and guide key technology decisions.
• 3 must-have skills: experience w/ production agentic systems. implementing, monitoring, and evaluating those systems.
• Nice-to-have skills: If they have worked with Agent Bricks in any meaningful capacity. Working with LangGraph. Self-motivated and willing to help other teammates. Not looking for someone who just wants to “shut up and code”

About the Role

We are looking for a Lead AI Engineer to design, build, and operate enterprise AI solutions. You will help evolve our platform from Retrieval-Augmented Generation (RAG) applications to agentic AI systems that leverage reasoning, orchestration, tool use, and autonomous workflows.

You will work closely with platform engineers, architects, and business stakeholders to build scalable, reliable, and measurable AI solutions. A key part of the role is ensuring AI systems can be evaluated, monitored, and operated successfully in production.

• Design, build, deploy, and support production AI solutions.
• Develop agentic workflows, tool integrations, and orchestration pipelines.
• Build and evolve RAG and agent-based architectures.
• Create evaluation frameworks to improve quality, groundedness, and reliability.
• Implement AI observability, tracing, and monitoring capabilities.
• Develop automated testing and regression validation processes.
• Integrate AI solutions with APIs, enterprise applications, and data sources. Design reusable AI patterns, frameworks, and components that increase platform scalability and team productivity.
• Establish engineering best practices and contribute to code reviews.
• Research and adopt emerging AI technologies where they provide business value.
• Partner with stakeholders to translate business problems into AI solutions
