DeepSeek's 150 Hires All Go to Engineering: DSec Agent Compute Stack Rework From OS to App Layer
量子位 · wechat · 2026-09-08
DeepSeek opened 150 roles (on a team of only 300-500), all concentrated in server-side development and Agent elastic compute engineering, targeting senior engineers with 2-10 years of experience. Lead Cui Tianyi framed it as a Scaling Law of headcount: scale breeds complexity, which demands more scale.
Elastic compute: from paper to large-scale engineering
- The platform side refers to DSec (DeepSeek Elastic Compute), first disclosed in the DeepSeek-V4 technical report: three Rust components—API gateway Apiserver, per-host Edge agent, and cluster monitor Watcher—interconnected via custom RPC atop the in-house 3FS distributed filesystem.
- Next steps: rework the entire stack from OS and VMs through networking, storage, up to app-layer scheduling and control plane. Low-level tuning lists "squeezing OS components to SOTA or hardware limits" as a plus.
Six server-side tracks span the full R&D chain
LLM research platform, Agent framework components, dev-efficiency infra (CI/CD, observability, exploring Agents for auto-diagnosis and RCA), DeepSeek API (ultra-large-scale serving), online services (tens of millions of DAU), and data engineering (Spark/Flink/Kafka/ClickHouse/Iceberg). Together they form a loop: models execute tasks in sandboxes → the platform records traces → data improves models.
The ideal candidate is expected to already develop with AI Agents daily—writing quality code in unfamiliar domains with AI assistance while catching Agent mistakes—marking a shift from "knowing how" to "knowing what to question and how to verify."
