Mission Summary

Motional's autonomous vehicles collect petabytes of data on the road every day. The Semantic Search Team manages data infrastructure, processing, and visualization for Motional's machine learning data. Our team also provides a scenario mining framework that other teams in Autonomy use to mine for complex and rare scenarios to improve our ML training model and av-stack performance.

As our data continues to grow, our team is looking for a Senior Software Engineer to design scalable data processing infrastructure and improve the efficiency of the data architecture and scenario mining framework for the entire Autonomy organization.

The Motional Pittsburgh office is located in the new Hazelwood Green development, a culmination of the city’s goal of restoring an economic driver to the neighborhood in a thoughtful, inclusive, and sustainable way. With views along the Monongahela river, the Pittsburgh office is in the heart of this new state of the art development.

  • Solid experience in AWS/Cloud (e.g., API Gateway, EKS, Lambda, OpenSearch, Redshift, S3)
  • Experience interacting with REST APIs and microservices
  • Ability to mentor junior engineers
  • Ability to communicate clearly to non-domain experts about potentially complex behaviors

Bonus Points (not required)

Motional is a driverless technology company making autonomous vehicles a safe, reliable, and accessible reality. We’re driven by something more.

Our journey is always people first.

We aren't just developing driverless cars; we're creating safer roadways, more equitable transportation options, and making our communities better places to live, work, and connect. Our team is made up of engineers, researchers, innovators, dreamers and doers, who are creating a technology with the potential to transform the way we move.

Higher purpose, greater impact.

We’re creating first-of-its-kind technology that will transform transportation. To do so successfully, we must design for everyone in our cities and on our roads. We believe in building a great place to work through a progressive, global culture that is diverse, inclusive, and ensures people feel valued at every level of the organization. Diversity helps us to see the world differently; it’s not only good for our business, it’s the right thing to do.  

Scale up, not starting up.

Our team is behind some of the industry's largest leaps forward, including the first fully-autonomous cross-country drive in the U.S, the launch of the world's first robotaxi pilot, and operation of the world's longest-standing public robotaxi fleet. We’re driven to scale; we’re moving towards commercialization of our technology, and we need team members who are ready to embrace change and challenges.

Formed as a joint venture between Hyundai Motor Group and Aptiv, Motional is fundamentally changing how people move through their lives.
