Machine Learning Scientist, Life Science Project
Software EngineeringMountain View, CA (HQ)
About the company:
X is Alphabet’s moonshot factory with a mission of inventing and launching “moonshot” technologies that could someday make the world a radically better place. We are a diverse group of inventors and entrepreneurs who build and launch technologies that aim to improve the lives of millions, even billions, of people. Our goal: 10x impact on the world’s most intractable problems, not just 10% improvement. We approach projects that have the aspiration and riskiness of research with the speed and ambition of a startup. As an innovation engine, X focuses on repeatedly turning breakthrough-technology ideas into the foundations for large, sustainable businesses.
About the team:
We are a team of scientists and engineers dedicated to creating transformative computational tools for biology. Our moonshot is to accelerate discovery and innovation in the life sciences, with applications in industrial biotechnology and synthetic biology. Our team is developing technologies that redefine what is possible in a rapidly evolving field. If you are excited to make a difference in this space, we’d love to talk with you.
About the role:
We’re looking for a motivated and versatile machine learning scientist who is passionate about using models to solve real world problems and enjoys working with complex, heterogeneous data. You will be working with our team of computational biologists and software engineers to develop machine learning models for cell biology based on cutting-edge data gathered by our own in-house lab. This involves developing and iterating on model prototypes, designing robust benchmarking experiments, and developing and scaling machine learning infrastructure as needed. You will also preprocess and analyze data from our lab team and our external partners to prepare it for modeling. This role requires expertise developing, evaluating, and scaling complex machine learning models for biological applications.
What you should have:
- Masters or Ph.D. in computational biology, computer science, physics/biophysics, chemistry, or other relevant field; or 5+ years equivalent practical experience
- Strong Python coding skills and practices in a team development context
- Experience training neural network models using modern ML frameworks (e.g., PyTorch/Jax)
- Experience working with biological data for machine learning, for example ‘omics or other genotype-phenotype data; knowledge of microbiology and metabolism a plus
- Experience scaling machine learning pipelines in the cloud
- Can understand the broader scientific/business context of a modeling task
- Can summarize modeling results clearly for audiences with different levels of technical expertise
- Honest, open communicator, takes initiative and high agency.
It’d be great if you also had these:
- Startup experience a plus
- Experience with Bayesian optimization a plus
- High speed of execution
