If you require reasonable accommodations at any stage of the application or interview process, please contact the People Operations Team at careers@upmetrics.com.

Research shows that while men apply to jobs when they meet an average of 60% of the criteria, women and underrepresented individuals only apply when they meet 100% of them. We believe that people of color, people from working class backgrounds, women, and LGBTQ+ people must be centered in the work we do. Hence, we strongly encourage applications from people with these identities, or who are members of other marginalized communities. If you think you have what it takes, possess transferable skills, are quick to learn, but don't necessarily satisfy every requirement or meet every qualification, we would still love to hear from you!

Applicants must be authorized to work in the United States. UpMetrics is unable to sponsor or take over sponsorship of employment visas at this time.
