Principal AI Engineer

Stratus, deriving from the Latin term meaning 'layer', offers an advanced set of MEP specific solutions that seamlessly layer across a contractor's entire workflow from design to fabrication to installation. Our team of seasoned industry experts, skilled technology leaders, innovators, and entrepreneurs understands that fabrication does not occur in isolation, and increasingly, it may not happen within your own fabrication shop. Through close relationships with our customers—who include some of the most innovative and largest MEP contractors—we have developed a suite of Stratus tools to digitize, automate, and optimize piping, plumbing, sheet metal, and electrical contracting. Stratus provides the software layer an MEP Contractor needs to optimize profits with true "Data Driven Contracting."

GENERAL DESCRIPTION

------------------------

The Principal AI Engineer joins our team as a senior technologist building foundation models, agentic AI systems, and generative AI tools for our products. You will work collaboratively to create and interpret design data that enhances design and engineering workflows, turning large-scale, multi-modal datasets into representations that power production ML systems.

As a Principal Engineer, you will set technical direction, mentor engineers, and drive best practices across cross-functional teams of ML research scientists and engineers, translating research ideas into production-grade systems.

KEY RESPONSIBILITIES

-------------------------

• Build foundation models and generative AI tools alongside a team of technologists.
• Design and build agentic workflows — multi-agent orchestration (e.g., CrewAI, LangGraph, AutoGen), tool use, multi-step planning, and human-in-the-loop checkpoints — to automate complex engineering tasks.
• Establish evaluation, guardrails, and failure-mode analysis for agent systems to ensure they are safe, reliable, and production-ready.
• Develop scalable data pipelines for diverse data...
