From the employer’s posting
We're looking for a rare individual who thrives at the intersection of cutting-edge deep learning architectures and high-performance computing. You will help shape the future of molecular machine learning by engineering high-efficiency implementations of advanced architectures for foundation simulation models, accelerating simulations to the limits of the hardware while maintaining fidelity to the underlying physics.
While we prefer candidates willing to relocate to San Francisco or New York City, we are willing to consider full-time remote candidates of exceptional talent who are willing to travel frequently to our two office sites. Travel is part of all roles at Achira, both to conferences and corporate on-site activities.
Take existing PyTorch and JAX, profile and optimize it without compromising model accuracy
Develop with frameworks like CUDA, Triton, Warp, etc. to accelerate performance critical code sections.
Liaise with NVIDIA to represent our needs and implement their tooling in our environment.
Work day-to-day with scientists to identify areas of greatest impact
What you’ll bring
All qualificationsCore experience
- At least two years of professional GPU optimization experience
- Deep understanding of GPU programming fundamentals
- Public track record of optimization work, such as on GitHub
- Experience collaborating on software projects in multi-person teams
Qualification wording

About the role
We file this job under ML Engineer, by the work the posting describes.
ML engineers put machine learning models into products. They write the code that trains, ships, serves and monitors models so a recommendation or prediction works for real users.
Postings ask for strong Python and software engineering, a framework such as PyTorch, cloud services, and more and more often experience with large language models.
A data scientist often works out which model to build; an ML engineer makes it run reliably in production.
