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, our first foundation model, built completely from scratch for aesthetic diversity and stylistic control.

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
