We also completed our first first employee tender offer and launched a community equity round, for our customers, agency partners, and club members.

• You love being a product manager as well as an engineer. Our product engineers drive and own products from end to end.

You are able to talk to customers, think through multiple approaches, and work with our teammates to find the right solution for each problem. You care about craft and translate the solution into bug free, easily understandable code and raise the engineering bar for those around you.

• Having a diversity of perspectives is important to you. You believe that having people with different backgrounds and perspectives creates a better team and a more holistic product.
