• Write robust and performant software to curate, transfer, and store large quantities of data from our robot fleets.
• Collaborate closely with ML and robotics engineers to continuously maintain and improve the data pipelines.
• Design on-robot triggers that determine if and when robot data should be uploaded.
• Automate ETL pipelines to make fleet-wide data easily queryable and available to train on.
• Automate data movement between data farms and deployment to cloud datacenters
• Build frontend tools for visualizing and automating labeling of web-scale datasets.

We'Re Looking For:

• A production-oriented engineering mindset with experience shipping reliable, scalable systems.
• A performance optimization savvy who is not only comfortable with low-level bits and multithreading, but also with high-level distributed systems.
• Expertise in Python and experience with C++ and distributed computing frameworks.
• A friendly, collaborative mindset, strong communication skills, and excitement to work hands-on in a dynamic, supportive team environment.
• A comprehensive portfolio demonstrating your specific contributions to large-scale data infrastructure projects.

Preferred Or Bonus Qualifications:

• Have built a petabyte-scale data-engine to handle a fleet of robots.
• Experience with the following technologies: Databases, Ansible, Docker.
• Familiar with general robotics and robot learning algorithms.
• Experience with edge computing and data synchronization in robotics applications.

Why join Persona AI?

• You'll shape technology that's redefining the possibilities of robotics and human interaction.
• Work alongside passionate teammates who value diversity, creativity, and continuous learning.
• Enjoy full access to advanced prototyping tools, labs, and the freedom to experiment and innovate.
• We offer competitive compensation, excellent benefits, flexible work environment, and equity opportunities.
