Principal Infrastructure Engineer

First and most importantly: our mission is to bring transparency and clarity to the world's data.

Our platform, Fifty One, is where AI work happens
. Our enterprise platform is the mission critical linchpin for managing unstructured data, model development, and AI systems at the world's largest companies.

We believe that open source is the way to lead the data-centric AI revolution. Our open source version has 4 million downloads to-date.

Our software massively impacts AI work across almost every vertical:
from self-driving cars to medical imaging to revolutionizing agriculture
, we are at the thrilling center of real-world AI advancement’s next wave.

And we’re built on three key tenets:

• We are all human beings
  : we strive to be a “human-first” organization and treat everyone with the respect, care, and flexibility that all people deserve.
• We are distributed
  : we believe in getting autonomy and power into the hands of people actually doing the work.
• We believe in the power of community.

We are fully remote, hiring for people based in North America and who are prepared to travel to at least 2 in-person retreats per year.
