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.
