About Rain:

At Rain AI, we’re creating a future with abundant and scalable artificial intelligence. We're building the world’s most cost and energy efficient hardware for AI. Our products achieve an order of magnitude improvement over the status quo by co-designing every layer of the AI stack, from circuits to algorithms. Our ultimate goal is to become the dominant hardware company of the AI era.

Rain AI is currently a Series A stage startup and backed by world leaders in AI. Our seed round was led by Sam Altman (Open AI). In addition, our current VC partners include Y Combinator, Daniel Gross, Jaan Tallinn, Founders X Fund, Airbus Ventures, Liquid 2 Ventures and Deepwater.

About the Role:

As a Senior Engineer in Simulation and Modeling, you will collaborate with the software, architecture, and IC design teams to deliver high-performance software simulation tools that accurately model the functionality and performance of Rain’s hardware platform. These tools play a critical role in Rain’s internal software and hardware development efforts and will be deployed to end-users as part of the Rain SDK, allowing customers to experiment with Rain hardware early in the product development life cycle. Through your efforts, our simulation tools will be easy to use, extensible, and will deliver maximum performance without compromising accuracy.

This is a remote role – you can work from anywhere in the United States.


  • Develop functional and cycle-accurate simulators of Rain’s SoC design
  • Collaborate with hardware architecture and IC design teams to ensure the simulation tools precisely match hardware behavior
  • Design and implement validation strategies to ensure the hardware and simulation tools stay in sync

  • Mentor junior engineers and be a shining example of development best practices


  • BS in Computer Science, Computer Engineering, or related fields
  • 7+ years in industry with experience with a focus on software simulation tools and hardware design
  • Excellent programming skills in C/C++ and SystemC
  • Experience with performance profiling and optimization
  • Track record of ownership of advanced software systems
  • Strong communication skills, both written and verbal
  • High degree of motivation and independence
  • Ability to work successfully in a distributed and remote environment

Preferred Qualifications:

  • MS or PhD in Computer Science, Computer Engineering, or related fields
  • Experience developing software simulators that model ML accelerators and/or SoC devices
  • Experience with open-source simulation tools such as qemu or SAIL
  • Experience working on AI/ML products or at AI/ML companies
  • Familiarity with the RISC-V instructions set
  • Experience with hardware bring-up and supporting early hardware test/debug

Our Benefits:

  • Medical Insurance with 100% coverage of employee premiums
  • Dental and Vision Insurance
