Research Engineer - job 1 of 2

About the Team

The Sora team is building large-scale ML capabilities from the ground up. We work at the intersection of research and infrastructure, designing and deploying the systems and algorithms that power high-impact, cross-functional initiatives. Our work bridges research ideas and production-grade systems in close collaboration with infrastructure, applied ML, and product teams.

About the Role

As a Senior Research Engineer, you will design, implement, and optimize large-scale ML systems. You’ll work across the stack—from algorithm design and model implementation to distributed systems and deployment—to bring state-of-the-art techniques into production. We’re looking for hands-on builders who thrive in early-stage, fast-paced environments, can navigate ambiguity, and are excited to create zero-to-one systems. This is not a purely research role—you’ll spend significant time writing and shipping high-quality code.

This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

• Design, implement, and evaluate large-scale ML pipelines and core system components.

• Build and integrate infrastructure to support model training, experimentation, and deployment.

• Collaborate with research scientists to translate algorithmic ideas into robust, performant systems.

• Own projects end-to-end—from prototype to large-scale production—balancing iteration speed with reliability

You might thrive in this role if you:

• Have taken ML systems from concept to production at scale.

• Have strong software engineering fundamentals (distributed systems, data storage, performance optimization) alongside applied ML skills.

• Are comfortable working across boundaries of research, engineering, and infrastructure.

• Enjoy both deep technical problem-solving and the scrappy execution required in a zero-to-one environment.
