Modeling Engineer","description":"Acceler8 Talent is seeking a Principal Performance Modeling Engineer to join an early stage startup backed by a Tier-1 VC that is rethinking AI infrastructure from first principles.Founded by industry veterans with a track record of shipping some of the industry's most successful products, this startup is innovating at the chip and system level to deliver an order of magnitude better performance-per-watt for inference, which would create a huge economic shift for anyone running large models.As a Principal Performance Modeling Engineer, you will act as technical lead on the development of performance and functional models that guide architecture decisions and accelerate hardware–software co-design in a fast-moving startup environment.Responsibilities:● Design, implement, and maintain processor simulators (performance and/or functional models)● Model microarchitectural components (pipelines, memory hierarchy, interconnects, accelerators)● Traces generation and curation to make them suitable for the targeted performance analysis goals● Analyze simulation results to inform architecture tradeoffs and optimizations● Collaborate closely with architecture, hardware, and compiler teams● Own critical simulation infrastructure from concept through production useExperience:● 5+ years of software engineering experience, ideally in systems, architecture, or EDA domains● Strong C/C++ and Python skills with large, complex codebases● Experience with processor simulators, architectural modeling, or performance analysis, especially “from-scratch” simulator development● Solid understanding of computer architecture and microarchitecture● Ability to work independently and make technical decisions in an early startupNice to Have:● Experience with AI/ML accelerators, GPUs, or heterogeneous systems● Familiarity with simulators such as gem5, gem5-SALAM, or proprietary modeling toolsIf you're looking for massive ownership, huge impact, and the opportunity to build from the ground up, please apply here or reach out to me at ltomaszko@acceler8talent.com to hear more.","company":"Acceler8
