Principal Data Engineer

Lennar is one of the nation’s leading homebuilders, dedicated to making an impact and creating an extraordinary experience for their Homeowners, Communities, and Associates by building quality homes and providing exceptional customer service, giving back to the communities in which we work and live in, and fostering a culture of opportunity and growth for our Associates throughout their career. Lennar has been recognized as a Fortune 500® company and consistently ranked among the top homebuilders in the United States.

The primary mission of the Principal Data Engineer role is to help our business evolve into a data, insights, and AI-driven organization. This position sits in our Data and AI team, which aims to drive improved business outcomes using insights and intelligence gleaned from data, infusing them into Lennar’s corporate fabric.

The Principal Data Engineer is a senior individual contributor who brings deep technical expertise across data platform engineering and data architecture. As AI becomes central to how Lennar operates, this role is foundational — the data platform this person builds and maintains is what makes enterprise AI possible. The Principal Data Engineer shapes how data moves through Lennar’s enterprise systems, sets the engineering standards the team builds against, and actively elevates the engineers around them through mentorship, architecture guidance, and hands-on collaboration. The Principal Data Engineer is a key role in maturing and scaling Lennar’s enterprise data fabric to support both analytics and AI at scale.
