Staff Software Engineer, Identity Platform

ABOUT THE ROLE You'll own Gamma's identity and authentication infrastructure as we scale beyond 100 million users. This means architecting the systems that enable secure authentication for every user interaction, building OAuth flows that power integrations with platforms like ChatGPT and Claude, and leading our migration to a modern identity platform. Your work will touch every user and enable critical partnerships that define how Gamma fits into the broader ecosystem. As a Staff Engineer focused on identity, you'll balance hands-on engineering with strategic technical leadership. You'll design authentication systems that balance security, usability, and performance, partner with security and compliance teams to meet SOC 2 and GDPR requirements, and establish best practices for authentication across Gamma's engineering organization. Our team has a strong in-office culture and works in person 4–5 days per week in San Francisco. We love working together to stay creative and connected
