Datalab | NYC | Full-time | Software Engineer and Head of Business Ops | $250k-$350k + 1.5-3% equity | https://www.datalab.to

A significant % of useful data is locked away in tough-to-parse formats like PDFs. We build tools to extract it, like https://github.com/VikParuchuri/surya (15k Github stars), and https://github.com/VikParuchuri/marker (19k stars). We also run an inference API and product.

We do meaningful research (we’ve trained several SoTA models), ship product, and contribute to open source. We’re hiring for 2 roles to help us scale:

Senior fullstack software engineer

  - work across our open source repos, inference api, and frontend product
  - interact with our user community
  - you’ll need to be pragmatic, and embrace “boring” technology.  Our stack is fastapi, pytorch, htmx, postgres, and redis.  We deploy to render, and do inference with serverless gpus.
  - requires having built something impressive, ideally an open source project

Head of business operations

  - first non-technical hire
  - work across multiple areas, including finance, hiring, and sales
  - you’ll need to be extremely organized and able to get a lot done
  - requires experience leading operations at an early stage

Email careers@datalab.to if you’re interested - include a link to something you’ve built if possible. You can also read more here - https://datalab-to.notion.site/careers-jan .
