Salary Range: The base salary range for this role is between $140,000 - $200,000 in the State of New York, the State of California and the State of Washington. This range is not inclusive of our discretionary bonus or equity package. When determining a candidate’s compensation, we consider a number of factors including skillset, experience, job scope, and current market data.

In the United States, employees within the New York, Seattle, and Miami metropolitan areas are expected to work from the designated office twice a week, unless there is a job-specific requirement to be in the office every work day. We believe our hybrid approach for those near our NYC, Seattle, and Miami offices increases productivity through more in-person collaboration where possible. Employees outside of these areas are considered part of our remote-first workforce.

At Gemini, we strive to build diverse teams that reflect the people we want to empower through our products, and we are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status. Equal Opportunity is the Law, and Gemini is proud to be an equal opportunity workplace. If you have a specific need that requires accommodation, please let a member of the People Team know.
