We are seeking a highly skilled and experienced Staff Research Scientist with strong ISA extensions experience. This is a high-level research and development role.

Key Responsibilities:

• Analyse dynamic language overhead: Profile V8 and ArkTS interpreter/JIT to identify operations that consume disproportionate cycles (type checks, inline cache misses, garbage collection barriers, dynamic dispatch, deoptimisation)
• Design ISA extensions: Propose new instructions or architectural features that accelerate common dynamic language patterns while maintaining backward compatibility and security boundaries
• Model in architectural simulators: Implement proposed extensions in GEM5
• Collaborate on RTL implementation: Work with digital design teams to refine instruction encoding, pipeline integration, and verification requirements
• Publish and patent: Document novel contributions through intern...
