• Architect training workflows that use user feedback and corrections to continually improve model performance.

• Apply computer vision to extract data from PDFs, scanned documents, and other unstructured formats.

• Build intelligent agents that interact with complex web interfaces using tools like Playwright or Selenium, and a strong understanding of DOM structures.

• Design robust evaluation pipelines and performance metrics for all models.

• Help architect scalable systems to support training, inference, and feedback pipelines.

• You’ll be building core systems from scratch.

Qualifications:

• 6+ years with Python development experience
