Job Description

At Underdog, we make sports more fun.

Our thesis is simple: build the best products and we’ll build the biggest company in the space, because there’s so much more to be built for sports fans.

• Background in test observability, reliability, or performance testing for consumer-scale apps.
• Passion for sports, fantasy gaming, or the live energy of sports betting products.

Our target starting base salary range for this position is between $135,000 and $160,000, plus target equity. The starting base salary will depend on a number of factors including the candidate’s skills and experience, among other things.
