AI writes it from your resume. You only have to send it.
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 sits in front of it as the primary channel for broadly and reliably distributing our AI services. It also powers our own Kimchi harness.
As a Senior Software Engineer, you will work on key features of our product. 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, and production rollout. Most projects ship in 1-4 weeks. You'll work directly with product and other engineering teams on problems that don't have textbook solutions.
We are currently hiring Senior Software Engineers for the Harness team.
OpenAI and Anthropic ship models. They also ship one harness each – the scaffolding that turns a raw model into something that can plan, execute, recover, and complete work. We ship a different kind of harness: one built for cost-conscious, long-horizon autonomy, running on inference infrastructure we control end-to-end. A decent model with a great harness beats a great model with a bad harness. The gap between what today's models can do and what you see them doing is largely a harness gap, and that gap is where we operate.
A background check may be conducted at the final stage of recruitment through a third-party provider, Checkr. Please note that Cast AI does not provide any form of visa sponsorship/work permit.
