REI
At Recreational Equipment, Inc. (REI), we exist to inspire and enable life outside for everyone. We believe that it’s in the wild, untamed and natural places that we find our best selves, so our purpose is to awaken a lifelong love of the outdoors, for all. Since 1938, we have been your local outdoor co-op, working to help you experience the transformational power of nature. We bring you top-quality gear and apparel, expert advice, rental equipment, inspiring stories of life outside and outdoor experiences to enjoy alone or share with your friends and family. And because we have no shareholders, with every purchase you make with REI, you are choosing to steward the outdoors, support sustainable business and help the fight for life outside. So whether you’re new to the outdoors or a seasoned pro, we hope you’ll join us.

Sierra Club
At the Sierra Club, we believe in the power of togetherness. Together, we remain committed to the fight for a healthy climate built on a foundation of environmental, racial, economic, and gender justice – a future where all people benefit from a healthy, thriving planet and a direct connection to nature. As the climate crisis and deeply entrenched systemic racism all fuel inequity, we will continue to fight for a bold, transformational agenda that recognizes the interconnectedness between our planet, our humanity, and our democracy. By recognizing that our destinies are tied, we continue to name that all things are fundamentally connected, and the overlap between ecology, race, gender, and representative government will move to either advance our collective humanity or to oppress it. Sierra Club is comprised of staff across the country and a network of local chapters that support our grassroots engagement. We are also proud to be a unionized employer, with two labor unions representing more than half of our employees. Please view www.sierraclub.org/careers/ for more information.
