Companies like Mercury, Flex, and Novo rely on Lithic's developer-friendly APIs, direct network connections, and flawless reconciliation to launch and scale card programs in weeks, not years.

We're building a future where access to better financial products materially improves people's lives, free from the constraints of 30-year-old mainframes and legacy processors.

We're a team of 160+ across 26 states and 7 countries, headquartered in New York City. 

We are hiring a Senior Software Engineer for our Treasury team to lead Lithic’s next phase of growth.
