Principal Model Optimization Engineer
Roblox, San Mateo, CA
The role
As a Principal Engineer on ML Platform, you will set the technical direction for these systems. You will find what slows ML engineers down or wastes compute and design durable fixes. You will measure the results and keep improving them until they show up as faster iteration, more reliable jobs and better use of every GPU.
What you will do
- Design platform capabilities that many teams adopt, so that one investment improves hundreds of use cases instead of one.
- Build GPU and compute management that keeps a scarce, mixed fleet busy. This covers quotas and priority tiers, preemption, scheduling across clusters, and capacity planning with Infrastructure.
