About Us:

At Braintree, we’re building products that make payments easier—so easy that they fade into the background, making entirely new kinds of interactions possible. Our full-stack payment platform lets companies build their own experiences and then scale their businesses around the globe. We have developer friendly APIs built to integrate with various platforms - Ruby, Python, Java, PHP, Node.js and .NET - and we also have SDKs for iOS, Android, and Windows.

Our technology fuels companies like Github, 37Signals, Uber, Airbnb, OpenTable. Heroku and more.

We're also in a unique position to greatly impact how merchants and customers interact. The product teams at Braintree work together with Venmo, the mobile payments company we acquired in 2012. Our joint offering, Venmo Touch, gives our users one touch purchasing within apps, eliminating the need to retype your credit card number inside each app you download. Recently acquired by PayPal, we're now in an even greater position to change the way people pay.


  • Protect sensitive data and applications in high-scale systems that are growing rapidly.

  • Keeping security top of mind as look to power our customers’ most important transactions.

  • Pair program regularly.

  • Proactive issue detection, tool creation, development of best practices and procedures, and even policy development.


  • Solid programming foundation; expect to spend a significant amount of time writing code.

  • Working knowledge of one or several object-oriented or functional programming languages.

  • Working knowledge of applied cryptography and how to effectively develop appropriate cryptographic solutions.

  • Previous wide-ranging experience in application security and policy development.

  • 3+ years experience developing software with particular interest in keeping things safe and secure.

Other things to know about us:

We’re polygots. We write most of our software in Ruby but don’t confine ourselves to using a single programming language. We use the best tool for whatever task is at hand. We pair program. We like object oriented programming. We test, obsessively. When we say we’re an agile software development environment, we mean it.  We’re pragmatic, not dogmatic, and we value our people.
