Software Engineer, Microservices Framework - Data Infrastructure

About the Team:

The Microservices Framework team focuses on in-depth research in programming languages, RPC frameworks, and high-performance middleware. We provide company-wide development frameworks, high-performance middleware, a service mesh, and a unified governance platform. In addition, we deliver comprehensive performance optimization solutions for the company’s microservices ecosystem.
You will have the opportunity to participate in cutting-edge R&D and collaborate with the team to build the next-generation microservices architecture.

• Key Responsibilities
• Cost Optimization: Identify high-impact optimization opportunities through cost and performance analysis, design actionable solutions, and partner with business teams to drive successful implementation.
• Technical R&D: Explore heterogeneous language communication (primarily Go and Rust) with a focus on performance optimization, including hardware acceleration, and conduct customized optimizations of the Go runtime.
• Performance Diagnosis & Optimization Platform Development: Build systematic platform capabilities to support service cost analysis, performance diagnosis, and semi-automated optimization.

Requirements:

• Minimum Qualifications

• Bachelor’s degree or above in Computer Science or a related field, with a solid foundation in computer science fundamentals.

• Proficient in at least one high-performance programming language such as Go, Rust, or C++, with experience in low-level performance optimization (e.g., CPU cache optimization, zero-copy techniques, lock contention handling).

• Familiar with performance profiling tools and Linux kernel tuning.

• Strong systematic problem-solving skills, with the ability to effectively identify and resolve complex issues.

• Good teamwork and collaboration skills.

• Preferred Qualifications

• Extensive experience in performance diagnosis and optimization of RPC frameworks, network libraries, and Go services.

• Experience optimizing systems handling traffic at the million-QPS level.

• Excellent communication skills, with the ability to drive cross-team technical initiatives to successful implementation.
