Job Description:

Reducto helps AI teams ingest real world enterprise data with state of the art accuracy. The vast majority of enterprise data — from financial statements to health records — is locked in unstructured file formats like PDFs and spreadsheets. We train vision models to read those documents the way a human would, and make it possible to build products, train models, and automate processes at scale.

Job Responsibility:

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

Requirements:

Philosophy: You are your own worst critic
You have a high bar for quality and don't rest until the job is done right
You ship fast, with high agency
You don't just voice problems but actively jump in to fix them
Experience: 2+ years of experience building real world applications and integrating LLMs into production systems
Language: You're exceptional at Python
Tools: Build your own tools as needed
Approach: 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 have:

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

What we offer:

Unlimited PTO
Lunch: Receive a free lunch to eat with your teammates daily at the office
Reimbursed Transportation
Insurance: Generous health insurance covering medical, dental, and vision
Health and Wellness Budget: We provide up to $150/mo reimbursement for health and wellness spending
