Job description

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

As a Frontend Engineer focused on UI and design systems, you'll partner with designers to translate high-fidelity mocks into production-ready components, building reusable, accessible, well-documented component libraries. You'll bring mastery of CSS, a strong eye for craft (spotting 1px misalignments and janky animations), and obsession with user experience. You'll ship fast but never sacrifice quality, knowing when to polish vs when to iterate.

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

Build pixel-perfect layouts, smooth animations, and responsive interactions with accessibility in mind

Own design system components from buttons and inputs to complex editor UI primitives

Implement polished micro-interactions and transitions that make the product feel magical

Optimize rendering, bundle size, interaction responsiveness, and maintain 60fps animations

Partner with designers to translate high-fidelity mocks into production-ready components

What you'll bring

3–5+ years of frontend engineering with deep React expertise

Strong eye for detail and craft with ability to spot 1px misalignments, janky animations, and inconsistent spacing

Experience building complex, interactive UIs like editors, design tools, or animation-heavy apps

Performance optimization skills including React rendering, CSS performance, and animation frame rates

Design system experience building reusable, accessible, well-documented component libraries

Obsession with user experience including thoughtful loading states, error handling, and responsive behavior

Collaborative, truth-seeking, low-ego, growth mindset with generous, helpful approach

(Nice to have) Experience with animation libraries or visual editing tools

Compensation range

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.

We're building on a full Typescript stack centered around some of the most modern and popular technologies.

We use our own custom AI prompting framework using JSX. We have a lot of custom tools built in-house, but also new ones like Vercel AI SDK .

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. 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.

Meet the team

We're a team of dreamers and doers building in beautiful San Francisco 🌉

We're kabbadi enthusiasts, pickleballers, dog herders, woodworkers, keyboard nerds, potters, and more — and we can't wait to meet you!
