Infrastructure Engineer

We process billions of financial records for major banks. Peak ingestion is about 2,500 records per second across MongoDB, Kafka, Bull, Redis, and Snowflake. We need to scale that 10x. We need someone to build the infrastructure that makes that possible without breaking things. This role focuses on reliability, test infrastructure, and deployment confidence This is greenfield work. Nobody owns this full-time today. You would be the first person whose entire job is building the systems that keep quality high as we ship faster. About Eisen Eisen is the first account offboarding platform for financial institutions. We handle escheatment, disbursement, and customer outreach for banks and fintechs. We help them close the loop on inactive accounts and get people back to their money. We handle SSNs, account numbers, and financial data. If we get something wrong, a bank’s customers are affected and regulators notice. We’re SOC 2 compliant, onboarding bigger financial institution customers, and adding new products constantly. The Work Your first project is designing and building our testing harness from the ground up. This is infrastructure work, not configuring someone else’s framework. Yo
