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 the core models and prompts that power Gamma. We weave together text, image, and layout generation to automate all the drudgery of building presentations and websites, and we use AI throughout our product. Your job is to elevate quality, evaluate new models, and push the frontier with new features and modalities.
This role is about productizing existing models, not training new ones. You'll focus on prompting, evaluating, and fine-tuning foundation models for maximum performance. With over 1 million AI-generated presentations and 6 million AI images created daily, you'll work at massive scale. You'll own our existing LLM and image prompts, build evaluation frameworks to measure quality, and constantly test new frontier models and methods. You'll also launch new modalities like voice and video, curate datasets for fine-tuning, and own uptime, latency, and costs.
You'll succeed here if you're a tinkerer who loves pushing the limits of foundation models. You need strong software engineering skills in TypeScript and Python, a data-driven approach to raising AI quality, and experience building and evaluating prompts at scale. If you get excited about mixing prompt engineering with traditional software engineering to unlock new AI capabilities, this is your role.
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 our existing LLM and image prompts, measuring and continuously improving quality at scale
  • Develop complex prompts for new features using AI JSX, balancing creativity with reliability
  • Build evaluation frameworks for our prompts and models, monitoring metrics and qualitative feedback to create better test sets
  • Drive the roadmap based on quality gaps, constantly evaluating new frontier models and methods
  • Curate datasets for fine-tuning open source models and launch new modalities like voice and video
  • Build analytics and tracking systems while owning uptime, latency, and costs across our AI infrastructure
What you'll bring
  • Prompt hacker: You're a tinkerer who loves seeing how far you can push the limits of a foundation model, with experience building and evaluating prompts at scale
  • Software engineer: Experienced developer comfortable in TypeScript and Python, excited about mixing prompt engineering with traditional software engineering
  • Data-driven: You embrace using data to raise the bar of AI quality, with skills in writing evals, designing metrics, and turning qualitative feedback into quantitative measures
  • Self-sufficient in gathering and cleaning data to inform prompt improvements and model evaluations
  • Experience working with modern LLMs, plus image models like Flux and Imagen (Nice to have)
  • Familiarity with AI tooling like AIJSX for prompting and Braintrust for evaluations (Nice to have)
Compensation range:
$180K - $300K, 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’ll fit right in if…
  • 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."
