Sift Science – Why Work For Us?

Unfortunately, evil exists. Fortunately, we're here to stop it! Fraud and abuse plague online businesses of all types, from marketplaces to payment processors, social networks to e-commerce stores.

Inspiring mission? Check. Cool technology? Check. A genuinely nice group of people to spend your work day with? Yep, that’s also a check. Come help us fight fraud and abuse with real-time machine learning.

Our secret sauce

Why do we love coming to work every day? No question: the people. At Sift Science, it's easy to be yourself (whoever that may be). Still, there are some common qualities that people who work here have in spades.


“This is the first place I’ve worked where everyone eats lunch together every day!” ...says pretty much every Sift Science employee, during their first week.

Nope, group lunch isn’t mandatory. It’s just that people really like spending time together, chatting about projects and passions, kicking around new ideas. Culture just happens naturally. 



We also like all types of organized fun. Happy hours, game nights, weekend hikes, morning basketball, whiskey club, movie nights, cookbook club, animal shirt Fridays…

The list of ways to enjoy yourself goes on and on. Don’t find something that’s up your alley? Just suggest it – we’re always up for learning something new.


San Francisco is at the heart of tech innovation and culture – and Sift Science is located smack-dab in the heart of San Francisco’s Financial District. Talk about a job with a view.

Have a walking meeting along the Embarcadero, grab a coffee at the Ferry Building, fit in a quick workout at the YMCA. There’s no better place to work and play.

Easy integration? Don't take our word for it!

Watch a brief excerpt from Michael Widell's talk at the Nordic API conference, where he uses Sift Science as an example of a product that is easy-to-integrate and has open, accessible, and easy to understand API documentation.

    Average Interview


    I applied online. I interviewed at Sift Science.


    I reached out to an employee to learn more about the position. After applying online, I had an initial phone screening with a recruiter and then a second phone interview with a current Business Development Representative. I then had an onsite interview where I spoke with 5 different members. The process was very clear and they provided information to make sure candidates know what to expect.
