hirify.global builds an AI-powered content operating system that lets teams model, create, and automate structured content across channels.

What you will do

• Build retrieval systems and knowledge bases from hirify.global datasets and external sources, including chunking, freshness, scoping, GROQ filtering, keyword search, and semantic search.
• Develop MCP endpoints, agent tools, and integrations extending Content Agent across hirify.global Dashboard, Slack, Linear, and APIs.
• Design agent orchestration loops, action sequencing, human escalation, and precise system prompts.

• Strong technical writing skills and the ability to create precise instructions for systems that interpret language literally.
• Experience designing evaluations, running experiments, and interpreting probabilistic results statistically.
• Experience with MCP, tool-use patterns, and agent architectures, or willingness to explore them.
