About the job
We are looking for a DS with several years of experience and a background in experiments and causality.  Understanding of hypothesis testing, causality (including the use of causal inference experimentation methods), and simple statistical modeling are the traits we are looking for. Data obsession is always wanted.  As the DS leader for the Payments Vertical, you would be a great fit for our team if you’re a self-starter who thrives on uncertainty, and who’s passionate about exploring the intersection of real business problems with huge (and often messy) data sets, and finding effective ways to simplify and focus on practical opportunities to deliver value to our customers. To succeed at Hopper you need the talent, drive, and experience to thrive in a highly performing company.
The vision of the payments team is to provide a magical and frictionless payment experience to our customers. We will do this by supporting all the major payment methods (‘unlocking choice’), optimizing our payment stack (‘frictionless payments’) and unifying and powering all payments flows at Hopper (Flights, Hotels, Homes, Rental Cars, Attractions & more) as well as our Hopper Cloud offering (Whitelabel solution). 
Our long term vision is to remove any financial barriers to travel and truly make travel accessible to everyone. It’s cheaper, better and easier to purchase travel with Hopper!

Despite the pandemic’s impact on the travel industry, Hopper has emerged stronger than ever. As the travel industry continues to rebound, Hopper has demonstrated significant outperformance with its category-leading mobile-only marketplace, delivering value to customers and supply partners with the company’s proprietary suite of fintech offerings. 
Here are just a few stats that demonstrate the company’s recent growth:
- Hopper’s valuation is now over $3.5B. The company’s valuation has more than doubled since early 2020. 
- The company grew its revenue by more than 300% YoY in 2021. Hopper’s monthly revenues are now 375% higher than its pre-pandemic high point and Hopper Cloud, Hopper’s new B2B initiative, is already 15% of its revenues and growing.

- Hopper’s recovery is faster than the market and its share of the air travel market in North America is now 300% higher than prior to the pandemic, according to MIDT.
- The company sells over $2B in travel and travel related financial services annually 
- Hopper’s fintech offerings, such as Price Freeze and Rebooking Guarantee, now represent over 70% of its air revenue.
- Given the success of its travel fintech, Hopper recently launched a B2B initiative called Hopper Cloud, where any travel provider can unlock a totally unique revenue stream by seamlessly integrating and offering Hopper’s travel content and fintech products. Hopper Cloud partners include Capital One, Kayak, Marriott, Amadeus,, and MakeMyTrip.
- The industry opportunity for Hopper Cloud is enormous as projections estimate that if all travel distribution channels offered travel fintech, it could increase the total consumer spend for the sector by $200 billion annually.
All this recent growth is just the beginning. There are still so many new opportunities we’re excited to tackle in the next year!
