Senior Support Engineer



Customer Service
Posted on Wednesday, July 12, 2023

Our mission is to make payments safer and easier for everyone. We started with a consumer product (privacy.com) that helps people spend more safely using virtual payment cards. Then we launched a simple, modern API to make our payment and card issuing infrastructure available to other startups, fintechs, and brands. Today, that infrastructure is known as Lithic, and it powers billions of dollars in payments for some of the most innovative companies in the world.

Lithic is a remote-first company and has a distributed team with an office in New York. That means that if you want to work remotely, you can! If you want to drop by the office or work fully in-person, you can do that, too! We’ve raised $100M+ from top-tier investors including Index, Bessemer, Stripes, and Tusk Venture Partners, with a recent Series C that will help us scale.

The mission of the Lithic support team is to enable customers to optimally utilize the Lithic platform. Our role involves troubleshooting, informing, alerting, educating, and establishing a framework that allows both the customer and Lithic to grow and scale. We are looking to recruit a Senior Support Engineer to further our mission, which includes participating in after-hours on-call rotations as needed.
