DeepSeek Is Hiring ~150 Senior Backend Engineers Because Agent Traffic Broke Its Systems
South China Morning Post·medium signal
Cui Tianyi, a former quantitative trading specialist who joined DeepSeek in March to lead its Harness team, announced roughly 150 open senior backend roles, a scale the company itself calls unprecedented. The stated cause is a sharp rise in system complexity from user demand and AI agent traffic, not model research. Roles cover the large-model research platform, agent framework components, R&D efficiency infrastructure, the DeepSeek API, online services and data engineering, with two-to-ten-year engineers as the focus.
