Piping & Excavation Foreman

Dandelion Energy • Rockville, MD

About The Position

As the Piping & Excavation Foreman at Dandelion Energy, you’ll be both a technical expert and leader for our geothermal Ground Loop Commissioning (GLC) operations in Maryland.
You’ll work side by side with field crews to excavate trenches, fuse HDPE pipe, flush and fill ground loops, and commission systems — while also serving as the go-to technical and operational resource for the Denver, Colorado area. You’ll play a critical role in ensuring that projects are delivered safely, correctly, and efficiently, and that your teammates have the training, tools, and support they need to succeed.
This is a player-coach role: you’ll be on site most days working on live projects, while also taking responsibility for team performance, safety, and quality.
No geothermal experience? No problem. We’ll train this employee in-house on fusion, pressure testing, and commissioning, as well as cover their IGSHPA fusion certification.
