Who We're Looking For
We are looking for a builder who will design and strengthen the API, internal tools, workflow automation, Slack/Notion integrations, and microservices layer that connect our AI-native operating system to real business systems.

- Owning the AI runtime glue layer: Manage the glue layer that keeps the AI agent runtime connected reliably to real work systems
tech stack
- Languages: TypeScript, Python
- Integrations: Slack API, Notion API, webhooks, queues, workers
- Backend/Infra: API design, microservices, event-driven architecture, production deployment
- Tools: internal tools, operator console, admin tooling, workflow automation
- AI/Automation: LLM, agents, MCP, automation tooling
Qualifications

- Experience with LLM, agent, MCP, or automation tooling
- Experience working with high ownership in a startup environment
special conditions

ABOUT KYNDOF
The house behind the work
Kyndof is a Seoul brand house behind 2000Archives, womenswear born from an archive of original 2000s garments, and 2000Atelier, a custom stagewear studio for K-pop artists. Design, pattern, sewing and finishing happen under one roof, and what is proven on stage flows into ready-to-wear.
