$140,000 - $210,000 a year
Working from 22+ countries, we're a collection of talented humans rich in diverse backgrounds, lifestyles, and cultures. Close has been 100% remote since 2016, creating an intentional workplace around asynchronous communication and collaboration. Every year we meet up somewhere around the world to spend time with one another. These gatherings are an opportunity to strengthen the relationships within our global community.

We practice a mature approach to the workplace -- manage your time effectively, communicate thoughtfully with your teammates and customers, and produce high quality work. We have impressive tenure amongst the team; we stay at Close because we love working with our colleagues, we appreciate the autonomy, and we thrive in an environment that challenges us to do our best work.

Unanimously, our favorite value is "Build a house you want to live in." We make decisions that are rooted in helping our customers become more successful. We care equally about the health of our business and the wellbeing of our people.

Our application process was designed to promote equitable and unbiased hiring practices. We ask a small series of questions that are similar to what would be asked in the first interview. This helps us learn more about you right from the start so please be sure to answer each question thoughtfully. Regardless of fit, you will hear back from us letting you know if we'll be moving forward.

While we are excited by all the opportunities that generative AI has unlocked, we request that you refrain from relying on AI tools when completing an application. We ask these questions because we want to get to know you, your experience, and your communication style. All responses are read closely by multiple humans and any obviously AI generated applications will be disregarded.
