Senior Backend Engineer, Cloud Infrastructure

Quick Facts

• Role: Senior Backend Engineer, Cloud Infrastructure

• Work style: Remote

Description

Build and modernize backend cloud infrastructure services, including refactoring and porting core orchestrator components to run natively on ARM platforms. You’ll implement NUMA allocation logic to reduce cross-talk latency on high-core ARM systems and update RESTful APIs to support nested virtualization and new instance plans. You will collaborate with SRE and QA to maintain service stability and ensure seamless deployment workflows.

Responsibilities

• Refactor and port core orchestrator services/features (vbin, LSS, LDM, VMAP, RS) for native ARM execution

• Implement NUMA allocation logic in Python to eliminate cross-talk latency

• Develop API updates and backend capabilities for nested virtualization and new instance plans

• Work with SRE and QA on stability and deployment workflows

Requirements

• Bachelor’s or Master’s degree in Computer Science, Computer/Electrical Engineering, Mathematics, or a related field

• Backend cloud infrastructure development experience

• Strong proficiency in Perl (legacy services) plus Go and Python

• Deep understanding of Linux OS internals, including process management and memory optimization

• Knowledge of RESTful APIs

• Awareness of ARM64 architecture, CPU affinity, and NUMA memory allocation

• Experience with VM lifecycle management and orchestration APIs
