We're looking for a Sr. Identity and Access Management (IAM) Engineer with a strong passion for security automation, identity governance, and modern infrastructure engineering. Joining Prosper's Corporate IT team, you will partner closely with our InfoSec and Systems Engineering teams, as well as stakeholders across the broader business, to proactively secure, automate, and streamline user access pathways for both our corporate applications and developer systems. Join our expanding team of skilled IT professionals dedicated to innovating and securing Prosper's platforms, utilizing state-of-the-art automation tools for the benefit of our customers, business, and employees.

-
Empower Emerging Tech: Securely evaluate and integrate cutting-edge, AI-first developer tools and environments (e.g., Cursor, Antigravity, Claude Code), ensuring compliance guardrails remain airtight while enabling forward-thinking engineering velocity.
