How a CTO Transformed Teams from Microsoft to Sina: Lessons in R&D Management

This piece is a second interview with CTO Wei Xiangjun, sharing his career path and management philosophy.

Microsoft Experience

Wei recalls that foreign firms offered good compensation and career focus, and he helped quantify employee abilities using a ten‑dimension model covering professional skill, competitiveness, and communication.

Joining Kingsoft

In 2012, former Microsoft executive Zhang Hongjiang moved to Kingsoft, and Wei followed, attracted by the internet shift. At Kingsoft, he led the development of the Kingsoft Fast Disk (cloud storage) product, organizing a layered team of elite, middle, and junior engineers, adopting agile, feature‑priority development.

The product launched early, briefly leading China’s net‑disk market, with rapid iteration cycles of three to four releases per month.

Sina Weibo Architecture Revamp

Wei later joined Sina Weibo, rebuilding its file‑storage platform for short videos, images, and attachments, and gained deep insight into scaling high‑traffic services. He authored “Architecture of a Billion‑User Weibo Platform” and explored advanced product architecture and high‑concurrency optimizations.

R&D Management Insights

Wei emphasizes that technical teams must innovate rather than merely execute, that external demands should be structured and scheduled, and that urgent requests need clear identification. Close collaboration with business units is essential.

Technical teams need self‑driven innovation and rhythm.

External requirements should be formalized, layered, and scheduled.

Urgent needs must be identifiable.

Partner closely with business departments.

Time Management for Developers

He advises developers to align work with their most alert periods, allocate 20% of time for learning, and apply the 80/20 rule to focus on high‑impact tasks, using methods like Pomodoro or GTD.

Career Planning After 35

Wei encourages engineers to reflect on future directions—technical vs. managerial tracks, industry focus, startup vs. large‑company environments—and to set SMART goals, ensuring long‑term passion and satisfaction.
