Job Summary

Zoox is on a mission to reimagine transportation and ground-up build autonomous robotaxis that are safe reliable clean and enjoyable for everyone. We are still in the early stages of deploying our robotaxis on public roads and it is a great time to join Zoox and have a significant impact in executing this mission. The ML Platform team at Zoox plays a crucial role in enabling innovations in large-scale Foundation models VLMs and VLAs to make autonomous driving as seamless as possible.

The Opportunity

Are you excited to drive our ML Performance Optimization initiatives and make our ML models that enable autonomous driving as fast and efficient as possible You will get to work with SOTA accelerators cutting-edge techniques in distributed training quantization distillation and pruning among other things working closely with all the Autonomy teams within Zoox - Perception Prediction Planner Simulation Collision Avoidance and have the opportunity to significantly push the boundaries of how ML is practiced within Zoox.

We build and operate the base layer of ML tools model development and serving systems that our applied research teams use for in- and off-vehicle ML use cases. You will work alongside a team of strong software engineers and act as a force multiplier for our internal customers. This team has many growth opportunities as we expand our robotaxi deployments and venture into new ML domains. If you want to learn more about our stack behind autonomous driving please look here. If you want to learn more about our ML Infrastructure here is one of our past talks at re:Invent.

In this role you will:

Design implement and operate cutting-edge ML Training OR Inference performance optimization techniques to scale our VLM VLA and Foundational models and deploy them efficiently in our robotaxi.
