Solving a critical bottleneck for modern AI teams: ingesting complex, real-world enterprise data (like PDFs and spreadsheets) with state-of-the-art accuracy.

Requirements

  • 2+ years of experience building real-world applications and integrating AI/LLMs into production systems
  • Exceptional proficiency in Python
  • Comfortable building internal tools (e.g., quick Streamlit apps) as needed to test hypotheses or create datasets.
  • Experience with advanced techniques like prompt engineering, fine-tuning, or building AI agents.
  • Actively keep up with the latest developments in ML/AI research.

Responsibilities

  • Integrating and optimizing LLM calls for critical document understanding tasks like structured extraction, form filling, and complex data parsing.
  • Building and improving scalable document processing pipelines that handle various unstructured file formats (PDFs, spreadsheets) at an enterprise scale.
  • Making critical improvements to API design and pre-processing algorithms (e.g., chunking, structured extraction) based on direct customer feedback.
  • Experimenting with new techniques and output structures to continually improve LLM accuracy and reduce latency.
  • Building internal tooling and evaluation systems (evals) to rigorously analyze failure cases and optimize model performance.
  • Working directly with the founders and customers to shape the product direction and engineering strategy in a dynamic environment.

Other

  • 1-5 years building 0-to-1 products, ideally in a startup setting
  • A quantitative, high-agency approach to building products. Ability to debug, experiment, and iterate fast. You are your own worst critic and have a high bar for quality ("no settling for 90%").
  • Ambitious, driven, and excited by hard work and moving quickly in an early-stage company environment.
  • Prior experience founding a company or building products at early stages.
  • Unlimited PTO
