Product Designer

About Kimchi

We're headquartered in Miami, but our impact is international. We take a global and intentional approach to diversity. Today, Cast AI operates across 34 countries spanning Europe, North America, Latin America, and APAC, bringing a wide range of perspectives into how we build and lead. 

Kimchi.dev is the complete coding platform: coding agents, inference layer, and spend console in one. It's a B2B, product-led platform for teams building software with AI agents — spanning a CLI coding agent, a desktop app, and IDE extensions (VS Code, JetBrains) that let engineers route work across 50+ open-source and frontier models, 2.5× cheaper than a commercial-only approach at the same quality.

For enterprises that want more control over how agents are used across their org, Kimchi adds advanced observability, budget attribution per user, team, and API key, hard spend caps, and self-hosted deployment in your own VPC. Inference runs on Cast AI's OMNI — automatically scaling, cost-optimized GPU infrastructure — so routing stays fast and cheap without teams managing GPUs themselves.

We're not stopping at coding. Chat and design workflows are coming next with Kimchi Studio.

Made by Cast AI — a Miami-headquartered, globally distributed team across 34 countries that hit unicorn status in January 2026 with a $50B+ backed investment pushing its valuation past $1 billion.

Unicorn momentum

In January 2026, we achieved unicorn status with a strategic investment from Pacific Alliance Ventures, the corporate venture arm of Shinsegae Group (a $50+ billion Korean conglomerate). Our valuation now exceeds $1 billion, and we're just getting started.

About the role

We're hiring a Senior Product Designer to join our small senior Kimchi design team. Our users are engineers and platform teams making real infrastructure and budget decisions — the category is moving fast, and so are we. We need someone senior enough to hold their own point of view, comfortable enough with ambiguity, ready to shape the product and curious enough to get their hands dirty in the actual codebase and dogfood the product.

This is a location-specific opportunity. We are currently accepting applications from candidates residing in the following European countries: Bulgaria, Croatia, Estonia, Greece, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia, and Ukraine.

Requirements:

• A portfolio or case study showing senior-level design work on developer tools, AI/LLM products, coding agents, or other technical, data-heavy SaaS platforms.
• A track record of owning research end-to-end — not just contributing to studies run by someone else — and using it to influence product direction.
