What does an exceptional Senior Full Stack Software Engineer do?

Every day, Clover devices handle the core credit card and point-of-sale processing for hundreds of thousands of merchants. Behind the scenes, we operate a cloud platform providing processing, storage and collaboration for merchants, application developers, service providers and our merchants' customers. Our devices and platform form the backbone of millions of payment interactions between merchants and their customers daily, and we do it in multiple countries.

The Team:

The SDK team facilitates second and third party integrators adoption models of "Clover as a Platform" and "Payments as a Service". We do this through the design, implementation, and support of SDK's written in four languages: Android, iOS, JavaScript, .NET. The result: we support billions of dollars of Gross Payment Volume (GPV) per year and are growing rapidly. The SDK Team publishes artifacts on NPM, Maven Central, NuGet, CocoaPods, and GitHub. We achieve amazing agility through the development and deployment of highly reliable, highly available robotics backed test automation integrated into our modern CI pipeline. Join an engineering team whose SDK's are used by thousands of merchants and developers around the world generating billions of dollars in transactions a year and used 24 hours a day.

As a Senior Full Stack Software Engineer, you can look forward to:

As a Senior Full Stack Software Engineer you will be tasked with improving/expanding our platform and product through the various Clover SDKs. You will also work closely with the Infrastructure Team and Business Operations Team to delivery improvements, support new features and triage production problems. Our engineers work in high performance squads dedicated to customer success and smooth daily operations.

We are pragmatic in balancing priorities and enjoy working in an iterative model where SDK features are released periodically, and bug-fixes are deployed as needed. In the coming year there will be a focus on ease of integration where we take dramatic steps to make it easier to build Point of Sale applications in a bug free manner. We plan to further grow our semi-integrated partnerships, expand services to deal with multi-site and enterprise merchant management, and ramp existing services up for further global expansion.

Specific task will likely include but not be limited to:
