Software Engineer, Trust & Safety

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.

Why this role matters now

AI has dramatically lowered the barrier for bad actors. Generating convincing phishing pages, spinning up realistic-looking fraudulent accounts, and producing abusive content at scale no longer requires specialized skill—a motivated attacker with access to widely available models can do it. The volume and sophistication of platform abuse is increasing faster than traditional approaches can keep up with.

At the same time, AI is transforming what's possible on the defensive side. A small, sharp T&S team equipped with frontier models can now build detection, triage, and response systems that would have required a team five times the size just a couple of years ago. AI-assisted content scanning, automated investigation workflows, and intelligent alert prioritization mean that a lean team can protect millions of users—if they build the right infrastructure.

About the role

Gamma is tackling one of the most critical challenges for any fast-growing AI platform: keeping millions of users safe while preserving the creative freedom that makes the product magical. As a Trust & Safety Engineer, you'll architect the systems that protect our platform from phishing, abuse, fraud, and malicious content, all while ensuring Gamma stays fast, reliable, and delightful to use.

You'll join a small, high-impact team building the foundation for trust at scale. You'll design infrastructure that serves millions, ship improvements daily, and build the internal tools that let our support teams act quickly on threats. You'll collaborate across engineering, product, and design to define how Gamma approaches safety for the long term.

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 detection and prevention systems for fraud, abuse, spam, and malicious content across millions of daily users
• Design and build scalable trust infrastructure including rate limiting, content scanning, anomaly detection, and account security
• Build tools that empower internal support teams to investigate and act on suspicious or malicious activity
• Investigate and resolve complex security incidents with limited context
• Partner with engineering and product to balance security with user experience
• Shape Gamma’s long-term trust and safety strategy and technical roadmap
• Leverage AI/LLM-based detection to stay ahead of AI-generated abuse—phishing, fraud, and malicious content that’s increasingly indistinguishable from legitimate activity
• Build automated triage and investigation workflows that let a small team operate at the scale of a much larger one

What you’ll bring

• 5+ years as a software engineer with a focus on abuse, spam, or fraud prevention
• Strong systems thinking and experience building highly available web APIs, with proficiency in at least one programming language and comfort working across a modern web stack
• Hands‑on experience implementing trust features like rate limiting, content detection, and fraud prevention
• Experience with event streaming systems (Redis, Kafka, or similar)
• Passion for security, user protection, and solving problems at scale

Nice to have

• Experience with AI/LLMs for content moderation, or familiarity with TypeScript, Prisma, Apollo GraphQL, or AWS
• Experience building AI-assisted moderation pipelines or using frontier models for automated abuse detection and response
• Familiarity with the evolving AI threat landscape—how generative models are being used for phishing, social engineering, and content abuse at scale

Compensation range :

The base salary for this full‑time position, which spans multiple internal levels depending on qualifications, ranges between $180K – $310K plus benefits & equity.

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.
• You believe AI should amplify creativity, not replace it.
• You know kindness and intensity are not opposites.
• You like working with people who care deeply: about their craft, their teammates, and the users on the other side of the screen.

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. Its 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."
