Performance Modeling Engineer

About the Company

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference.

Responsibilities

• Develop comprehensive performance models and projections for our architecture across varying workloads and configurations
• Profile and analyze deep learning workloads on our hardware to identify micro-architectural bottlenecks and influence optimization opportunities
• Drive hardware/software co-optimization by identifying where architectural features can unlock performance improvements
• Run regressions and validate performance models against real systems and silicon
• Inform next-generation architectural decisions by pathfinding across system and silicon options during design, proof-of-concept, and architecting phases

Requirements

• Strong performance modeling and analysis skills with experience building analytical-based or simulation-based performance models
• Solid understanding of computer architecture and micro-architecture, particularly for accelerators
• Experience profiling and analyzing deep learning workloads on hardware accelerators (GPUs, TPUs, ASICs, FPGAs, or others)
• Solid software engineering fundamentals with an eye toward auditability and maintainability

Preferred Qualifications

• Deep knowledge of GPU architectures and/or programming models like CUDA
• Experience mapping models to multi-chip inference systems
• Familiarity with transformer model architectures and inference serving optimizations
• Experience with architecture simulators and performance modeling tools (gem5, trace-driven simulators, custom models)
• Exposure to ASIC, FPGA, or CGRA-based accelerator development and hardware/software co-design principles
• Published research in computer architecture, ML systems, or hardware acceleration

Benefits

• Medical, dental, and vision packages with generous premium coverage
• $500 per month credit for waiving medical benefits
• Housing subsidy of $2k per month for those living within walking distance of the office
• Relocation support for those moving to San Jose
• Various wellness benefits covering fitness, mental health, and more
• Daily lunch + dinner in our office
• Unlimited compute budget subject to ROI justification
