Position: Senior Software Engineer, Processing

Location: Remote

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

The Processing team builds and maintains the real-time interfaces between Lithic and external payment networks. Every card authorization, clearing message, and settlement file flows through systems this team owns. The team manages both online and batch transaction flows across Mastercard, Visa, and Amex, along with transaction enrichment, disputes processing, and network compliance. The systems we maintain have strict latency and uptime requirements, because they sit on the critical path for every card transaction. The team also manages the physical network peering with card network partners, so infrastructure and networking expertise are important. The team primarily uses Java, Python, and Kotlin on AWS.

What you'll do:

Ensure high reliability, low latency, and correctness for Lithic's transaction processing interfaces…
