Job Description

Rain is the fastest-growing earned wage access (EWA) fintech in the U.S., serving 3.5 million employees and backed by top investors like QED and Prosus. We’ve raised nearly $400M in funding—including the largest Series A in fintech history—and just closed our Series B to fuel our next stage of hypergrowth.

We are seeking a skilled and driven Senior Application Security Engineer to join Rain’s growing Security team. This role demands a proactive approach to secure software development and cloud-native defense. You will partner closely with engineering and development squads, and work alongside our Cloud Security and GRC team members to improve Rain’s application and platform security posture.

This position is technically grounded, requiring direct engagement in application-layer matters and security reviews, while also contributing to cloud security automation, awareness initiatives, and secure engineering practices across the SDLC.
