About The Position

As a Backend/AI Engineer, you'll work on our core API that powers document parsing for hundreds of companies. You'll integrate cutting-edge LLMs, optimize document processing pipelines, and build the infrastructure that makes state-of-the-art document understanding accessible at scale.

Requirements

• You are your own worst critic. You have a high bar for quality and don't rest until the job is done right—no settling for 90%. We want someone who ships fast, with high agency, and who doesn't just voice problems but actively jumps in to fix them.
• You have 2+ years of experience building real world applications and integrating LLMs into production systems
• You're exceptional at Python
• Build your own tools as needed—like a quick Streamlit app to test hypotheses or create a dataset.
• A quantitative approach to building products. Ability to debug, experiment, and iterate fast. You should be comfortable getting hands-on with the full development lifecycle, from ideation to shipping to users.

Nice To Haves

• Have prior experience founding a company or building products at early stages
• Have experience with prompt engineering, fine-tuning, or building AI agents
• Are ambitious and driven, and care a lot about doing great work with great people
• Keep up with the latest developments in ML/AI

Responsibilities

• Integrating and optimizing LLM calls for structured extraction, form filling, and document understanding tasks
• Making improvements to API design and pre-processing algorithms (chunking, structured extraction, etc.) based on customer feedback
• Building and improving document processing pipelines that handle everything from PDFs to spreadsheets at scale
• Experimenting with new techniques and output structures to improve LLM accuracy and reduce latency
• Building internal tooling and evals to better understand/analyze failure cases
• Working directly with the founders and customers to shape the product direction and engineering strategy
