Senior Software Engineer | Kimchi

About the Position

Why Kimchi?

Kimchi is the AI platform inside CAST AI. We started by helping companies run LLMs on their own Kubernetes clusters and now we’re providing a managed variant of those same capabilities.

Our Infrastructure today

Multi-model inference (MiniMax, Kimi, GLM-5, Nemotron, DeepSeek) with intelligent routing, an OpenAI-compatible API and deployment ranging from our GPUs to your own VPC. The inference layer is the foundation and the API is what sits in front of it as the primary channel for broadly and reliably distributing our AI services and powers our own Kimchi harness.

We are hiring across multiple teams!

As a Senior Software Engineer, you will have the opportunity to work on different key features of our product. All of these are high-agency roles across multiple parts of the tech stack that minimize process friction that would otherwise prevent you from shipping.

In every team you will own features end-to-end: design, implementation, testing, production rollout. Most projects ship in 1-4 weeks. You’ll work directly with product and other engineering teams on projects.

• Design, implement, and test key features of our AI platform
