Job description

ABOUT KREA At Krea, we are building next-generation AI creative tools. We're dedicated to making AI intuitive and controllable for creatives - our mission is to build tools that empower human creativity, not replace it. We believe AI is a new medium that allows us to express ourselves through various formats - text, images, video, sound, and even 3D. We're building better, smarter, and more controllable tools to harness this medium. We recently took this a step forward with the launch of Krea 2 krea.ai, our first foundation model, built completely from scratch for aesthetic diversity and stylistic control, and with Krea 3 krea.ai - our new image editing model. We've raised over $83M and are backed by world-class investors such as a16z, Bain Capital, and Abstract. We work full-time and in-person at our waterfront office in San Francisco. We care about creativity: our team includes musicians, designers, visual artists, and engineers. Some examples of things you will do: - Build and maintain APIs and UI flows for web + mobile in Svelte/SvelteKit, TypeScript - Design interactive, responsive front-end experiences—drag-and-drop, real-time canvas polish, smooth and responsive UI animations - Optimize frontend performance: minimize render latency, profile UI with virtual DOM techniques, deliver seamless WebSocket image streams - Design and maintain backend services (Node), DB models (Postgres + Redis caching/pooling) - Kickstart a Public API project to serve Krea AI models to millions of developers - Diagnose HTTP/3 and WebSocket related issues both on the client side and the server side - Drive real-time image & video generation pipelines via low-latency APIs - Improve observability and alerting using OpenTelemetry tools - Implement enterprise features: Audit Logs, SAML/SSO, SCIM provisioning - Bonus: Scale our infra architecture through deep understanding of our AWS EKS GPU clusters or Kubernetes operators Strong candidates may have experience with the following: - Solid full-stack JS/TS engineer with frontend focus—component design, UI state, animations, client performance - Experience with SvelteKit or similar frameworks, real-time UI via WebSockets - Comfortable designing APIs, database schemas, caching strategies - Familiar with infra and scale: Kubernetes, Postgres, Redis, observability stacks - Side projects or open‑source contributions in UI/infra are plus - Bonus: prior work on enterprise auth features, GPU workloads, ML or image/video pipelines Stack: - Frontend: Svelte/SvelteKit - Backend: Node + TypeScript, Postgres, Redis - Realtime: WebSockets, HTTP/3 - Infra: AWS EKS GPU clusters, Kubernetes - Observability: Prometheus, OpenTelemetry, Axiom/HyperDX - Tools: GitHub, Slack, Notion WHAT WE OFFER - Team: Work alongside a world-class team building the future of AI creative tooling - Impact: Significant scope and company-wide impact - Competitive compensation: generous salary & equity packages - Health & wellness: 100% health & 99% dental/vision insurance premiums covered for employees, health FSA accounts, & long-term disability coverage - Time off: Flexible PTO policy - Financial planning: 401k with a 4% company-sponsored match - Meals in the office: breakfast, lunch, dinner - you name it, we'll cover it - Transit: Ubers covered to & from the office - Sponsorship: We're open to sponsoring international visas where we can (e.g., STEM OPT, OPT, H-1B, O-1, E-3). - And more!
