• Excellent communication skills, written and verbal, with attention to detail and accuracy.


• Demonstrated ability to communicate and collaborate in a small team environment


• Experience with Solidworks, Solidworks PDM, Solidworks Flow Simulation and Arena (ECO/Lifecycle PDM).


• Proficient computer skills and knowledge of relevant software such as G-suite of tools or MSOffice Suite and Slack preferred.


• Basic Dimensioning and Tolerancing experience in accordance with ANSI Y14.5M including general understanding of tolerance build up and manufacturability


• Experience with AHRI and UL Safety requirements is a plus.

Benefits/Perks:

• Health/Dental/Vision insurance


• 401k plan


• Stock/Equity options


• Paid Sick and Vacation time (PTO)


• 40-hour workweek, overtime available


• Training support including on-the-job and virtual/online-based courses

You’ll love working at Dandelion because:

We’re solving the world’s hardest problems. You’ll have the opportunity to pioneer renewable heating and cooling from the ground-up (literally). There’s no established playbook for fighting climate change, so your work will be messy, challenging, and build a better, cleaner world.

We’re good people. It sounds simple, and it is. We are passionate, vision-driven, low-ego, and treat one another with kindness and respect. We challenge ideas here, not people.

We hold each other accountable. We celebrate our wins and learn from our losses. We’re honest, realistic, and transparent across all areas of the business, every day -- not just at our monthly all-hands meeting.

************************************

Since spinning out of Google X in 2017, Dandelion Energy has been an energy innovation company working to electrify home heating. We create and install geothermal heat pumps to replace fossil-fueled furnaces and boilers. We’ve grown into an organization of over 100 employees and have become the largest residential geothermal heat pump installation company in the United States. Our carbon impact to date is the equivalent to taking over 25,000 cars off the road... and that impact is accelerating with our growth!

Our cross-disciplinary team consists of experts in geothermal, drilling, heat pump software engineering, HVAC installation, solar and solar financing, behavioral economics, and high-growth operations amongst other backgrounds. With the potential to catalyze and scale a widespread transition to sustainable and affordable heating and cooling, our work is both complex yet rewarding. We are working to create a wholesale shift in how people heat and cool their homes — join us!
