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 (OpenAI). 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 Compiler Engineer at Rain, you will participate in the design, implementation, and productization of an optimizing ML compiler for Rain’s AI accelerator products. In collaboration with other members of our world class compiler team, you will deliver software that efficiently maps ML models to Rain’s hardware for inference and training, blending the use of open-source tools, known compiler techniques, and novel algorithm design.

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


  • Develop an optimizing compiler frontend that provides state-of-the-art compilation from ML frameworks to customized lower-level IRs
  • Work collaboratively with compiler backend engineers to ensure the high performance and resource efficiency of generated code (while being mindful of compilation time)
  • Tackle compilation and performance problems in a boundaryless fashion, working seamlessly with members of the compiler, runtime, and hardware teams
  • Write well-documented and tested code, participating in the development of testing infrastructure, debuggers, and performance analysis tools
  • Participate constructively in design and code reviews of your work and the work of others
  • Work closely with ML experts to efficiently map emerging models to Rain’s hardware, including cutting-edge quantization and training algorithms
  • Stay up to date with the latest research and trends in compiler design and implementation
  • Mentor and provide technical guidance to junior engineers


  • BS in Computer Science, Computer Engineering, or related fields
  • 7+ years of experience in compilers and programming languages
  • 3+ years of experience developing AI/ML compilers targeting deep learning applications
  • Excellent programming skills in C/C++, Python, or similar high-level languages
  • Experience with standard ML frameworks such as PyTorch, ONNX, and TensorFlow
  • Strong communication skills, both written and verbal
  • Exhibit a high degree of motivation and independence
  • Ability to work successfully in a distributed and remote environment

Preferred Qualifications:

  • MS or PhD in Computer Science or Computer Engineering, with a focus on compilers and/or software development for AI accelerators
  • Familiarity with open-source compiler technologies such as TVM, XLA, and MLIR
  • Experience writing compilers for SoC architectures – especially multi-core architectures
  • Familiarity with deep learning models and willingness to learn novel algorithms
  • Experience with using generative code techniques (e.g. TableGen, GitHub Copilot, ChatGPT)

Our Benefits:

  • Medical Insurance with 100% coverage of employee premiums
  • Dental and Vision Insurance
  • 401k match
  • Unlimited PTO + all federal holidays
  • Company wide time off during the holidays and in the summer
  • Parental leave policy
  • Work from anywhere in the United States
  • And more!

The anticipated annual base salary for this position is $220,000 - $300,000. This range does not include any other compensation components or other benefits that an individual may be eligible for.
