Lead the top-level design and long-term planning of the company's unified Microservice governance system, covering various communication methods like RPC, messaging, and gateways, to build a stable, efficient, and intelligent service governance platform.
-
Spearhead the R&D and implementation of adaptive governance algorithms, including but not limited to adaptive rate limiting based on queuing theory or Little's Law, adaptive circuit breaking based on error rates and response times, and adaptive load balancing based on node load and health status.
-
Conduct in-depth research into the core mechanisms of mainstream RPC frameworks (e.g., Dubbo3, gRPC), including service discovery, load balancing, serialization protocols, and threading models, and lead the deep customization and performance optimization of these frameworks Take charge of the architectural evolution and high-availability construction of core Middleware such as configuration centers (Apollo), service registries (etcd, Nacos, ZK), and distributed task schedulers (XXL-JOB、Argo Workflow), ensuring the ultimate stability of foundational services Design and promote the platform-level implementation of advanced release strategies like canary release, blue-green deployment, and traffic dyeing to improve R&D delivery efficiency and the stability of system changes.
-
Build a resilience-oriented architecture with a "desired state" mindset, introducing chaos engineering principles and tools to proactively identify system vulnerabilities and continuously enhance the system's anti-fragility.

-
Rich architectural design experience in the Middleware domain, capable of designing and implementing complex distributed systems from scratch (0 to 1).
-
Proven experience and successful cases in areas like adaptive algorithms, full-link stress testing, or chaos engineering are highly preferred.
-
Excellent abstraction skills and architectural thinking, adept at modeling complex problems and designing elegant, scalable systems.
