DeepSeek is intensifying hiring for its newly formed Harness team and exploring self-built data-center capacity in Inner Mongolia, according to Pandaily and other outlets. Pandaily reports the company launched an online recruitment drive on June 21 led by Harness team lead Cui Tianyi. 36Kr and Verdent cite internal posts and job listings showing open roles for Agent Harness researchers, R&D engineers, and product managers focused on code-agent products, sometimes referred to as DeepSeek Code. Pandaily and BigGo report this hiring follows a Series A of 51 billion yuan (~$7.4 billion), closed June 16, 2026, with investors including Tencent, JD.com, NetEase, and CATL. Pandaily attributes commentary from IDC China VP Zhou Zhengang on the economics of self-built clusters. 36Kr and Verdent describe Harness as a systems layer converting foundation-model capabilities into usable agent workflows, handling context management, tool invocation, and execution control. BigGo frames Harness as the "model steering layer" and links the effort to broader interest in programming agents. Verdent notes DeepSeek Code is a working name in hiring posts rather than a released product.
