Staff Software Engineer, Platform

ABOUT THE ROLE You'll own critical platform infrastructure supporting 70M+ users and scaling to hundreds of millions. This means architecting the core data model and storage systems powering Gamma's business, building real-time collaborative editing systems, high-volume event pipelines, and public APIs while driving technical strategy for databases, caching layers, distributed systems, and observability. You'll lead major infrastructure initiatives including database migrations, architecture refactors, and performance optimization at massive scale. As a Staff Engineer on the Platform team, you'll define engineering standards and best practices across backend teams while mentoring engineers on system design, scalability patterns, and production excellence. You'll make critical build vs buy decisions, balance technical debt paydown with feature velocity, and collaborate with leadership to shape our multi-year platform roadmap. You'll bring high technical judgment, knowing when to over-engineer vs under-engineer and when perfection matters vs good enough. 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, with flexibility to work from home when focus matters most.
