How we are managing through the COVID pandemic and its impact on our team?

These are unprecedented times and we understand COVID-19 is impacting everyone differently. Our primary goal from the beginning of the pandemic has been to ensure employee safety. We went from optional to mandatory work-from-home very quickly in early March, and we have told employees that they can work remotely through July 2021 to allow them to plan accordingly. 

We have also rolled out several initiatives to help our team successfully navigate the uncertainty associated with COVID-19. These initiatives have included providing funds for home office improvements, medical reimbursements, free meditation/mindfulness tools, mandatory “Me Days” away from work, company-wide days off, and fun opportunities to connect live with teammates each week (such as virtual escape rooms). We continue to examine different benefits, tools, and processes that best support our employees as we continue to work remotely and eventually begin transitioning back to the office.


  • Competitive salary, equity, and career development opportunities
  • 100% coverage on many health, dental, and vision insurance plans
  • Pre-tax commuter benefits, 401k, and FSA
  • Budget for the technology tools you need — whether a laptop, monitor, or special software
  • Unlimited vacation days and annual $1,000 vacation stipend

We are proud to be an equal opportunity workplace committed to building a team culture that celebrates diversity and inclusion.
