Astrus - AI-powered Microchip Design

At Astrus, we are using AI to automate microchip design, starting with the biggest bottleneck, analog layout. Our mission is to radically improve global computation and empower chip designers to create the world's most advanced microchips with AI. Astrus is backed by top-tier VC firms: Khosla Ventures, HOF Capital, and 1517 Fund.

📍 Location: Toronto or Waterloo, Canada

ABOUT THE ROLE

As the Computational Physics Lead, you will take charge of designing and developing the core simulation software that guides our AI-powered microchip design platform. This software will evaluate millions of AI-generated analog layouts, scoring them based on performance metrics grounded in the physics of electronics, solid-state physics, and semiconductor manufacturing.

This role requires a deep understanding of computational physics and the ability to model electrical phenomena in software. You will collaborate closely with our AI, development, and chip design leads to ensure seamless integration into the broader AI system.

WHAT YOU WILL DO

Lead the development of high-performance, physics-based simulation software to evaluate analog layouts at scale, ensuring speed, precision, and accuracy.
Develop and optimize parasitic extraction models to simulate and assess electrical characteristics such as resistance and capacitance based on the physical properties of AI-generated layouts.
Collaborate with the AI, software, and chip design teams to ensure that simulation models are integrated effectively.
Work closely with the Analog Design Lead to align simulation models with real-world circuit behaviors.
Design methodologies for performance evaluations, ensuring AI-generated layouts meet industry standards.
Continuously explore and implement innovations in computational modeling techniques, improving simulation efficiency and accuracy as the product evolves.
Optimize simulation performance in high-performance computing environments, ensuring the system can handle large-scale analog layout simulations efficiently.
