Compiler Optimization Engineer

About the RoleWe are seeking a Compiler Optimization Engineer to lead the development of our intermediate representation (IR) and optimization pipeline. In this role, you will be responsible for bridging the gap between high-level model frameworks and our backend code generation, directly impacting the execution speed and efficiency of next-generation workloads.If you excel at transforming complex data flow graphs, designing efficient IRs, and implementing performance-critical transformation passes, we want to hear from you.Key Responsibilities:Pipeline Development: Build and refine the middle-tier optimization layer of our specialized compiler stack.Pass Implementation: Program and deploy advanced graph-level transformations, including multi-operator merging, memory layout restructuring, redundant code stripping, and constant propagation.IR Evolution: Architect and adapt our internal intermediate representation to accommodate evolving algorithmic structures and hardware capabilities.Performance Analysis: Evaluate compilation bottlenecks and leverage execution data to drive measurable gains in system throughput and latency.Cross-Functional Collaboration: Partner closely with upstream frontend teams and downstream code-gen engineers to maintain clean API boundaries and seamless data flow.Qualifications:Education: Bachelor’s degree in Computer Science, Computer Engineering, or a related technical discipline (or equivalent practical experience).Compiler Expertise: 4+ years of professional experience specializing in compiler design, with a strong emphasis on IR architecture or optimization pass development.Technical Depth: Deep understanding of graph-level manipulation techniques, including tiling, fusion, and layout optimization.Systems Programming: 4+ years of hands-on development experience using production-grade C/C++.Communication: Strong technical writing skills with the ability to document complex architectural decisions clearly.
