About us
We're building the creative layer for modern communication. Every month, over a billion people make presentations — but the tools they use to make them haven't evolved in decades. We're changing that, using AI to disrupt a massive market.
📈 Millions of people rely on Gamma to create, teach, and persuade, creating more than 1 million gammas every day.
💻 We see Gamma as the next great workplace tool, combining viral B2C love with a massive B2B opportunity. We believe AI can be a true creative partner: one that understands context, clarity, and taste.
💸 We’ve reached a $2.1B valuation, crossed $100M in annual recurring revenue, and have been profitable since 2023.
💙 We're an imaginative, passionate team who takes our work seriously, but not ourselves. Our culture is warm, a little quirky, and fueled by curiosity.
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, with flexibility to work from home when focus matters most.
What you'll do
- Own Gamma's end-to-end authentication and authorization systems, ensuring security, reliability, and excellent user experience
- Lead the technical strategy and execution for migrating 100M+ users from AWS Cognito to a modern identity platform
- Design and implement OAuth 2.0 and OpenID Connect flows that enable Gamma to act as an identity provider for third-party integrations
- Build and maintain SSO integrations (SAML, OIDC) for enterprise customers
- Partner with security and compliance teams to ensure identity systems meet SOC 2, GDPR, and regulatory requirements
- Collaborate with product and engineering teams to implement authentication features like MFA, passkeys, and session management
What you'll bring
- 8+ years of software engineering experience with at least 3 years focused on identity, authentication, or security systems
- Deep expertise with OAuth 2.0, OpenID Connect, SAML, and modern authentication protocols
- Hands-on experience acting as an OAuth provider and implementing authorization servers
- Proven track record executing large-scale identity migrations (millions of users) with zero downtime
- Strong understanding of identity providers (Cognito, Auth0, WorkOS, Okta) and their tradeoffs
- Expert knowledge of authentication security best practices: password hashing, token management, credential storage, session security
- Experience with WorkOS, AWS Cognito, or Auth0 in production environments (Nice to have)
- Knowledge of WebAuthn, FIDO2, and passwordless authentication (Nice to have)
- Experience building developer-facing authentication SDKs or APIs (Nice to have)
- Experience working at a high-growth SaaS company with enterprise customers (Nice to have)
Compensation range:
$230K - $310K, plus competitive equity.
Final offer amounts are determined by multiple factors, including but not limited to experience and expertise in the requirements listed above.
If you're interested in this role but you don't meet every requirement, we encourage you to apply anyway! We're always excited about meeting great people.

Life at Gamma

- You get energy from small teams doing big things.
- You love when design, code, and storytelling overlap.
- You default to action, even when the answer isn’t clear yet.
- You value details, but know when to ship and move on.
- You bring both the spreadsheets and the sparkle, equal parts workhorse and unicorn.

💙 Who we are
Gamma is full of imaginative, passionate people who take their work seriously but not themselves. The culture is warm, a little quirky, and fueled by curiosity. It’s the kind of place where you’ll debate a pixel on Monday, laugh over someone’s keyboard setup on Tuesday, and ship something remarkable by Friday.
We care about craft, move with intention, and don’t mind getting a little scrappy. It’s fast, creative, and occasionally chaotic — but that’s what makes it interesting.
💬 Here’s a bit about what it’s like to work here, from people on the inside:
We asked the team what makes Gamma, Gamma. Here were some of their answers:
- "quirky, inspiring, fun, a little wild in the best way"
- "You can have an idea and just run with it."
- "Everyone’s talented and humble — the mix keeps you sharp."
- "We ship cool stuff, learn a ton, and laugh a lot doing it."
