Job Description

Backend/AI Engineer

Join to apply for the Backend/AI Engineer role at Reducto.

About Reducto

Reducto helps AI teams ingest real world enterprise data with state of the art accuracy. The 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, enabling products, training models, and automating processes at scale.

The Opportunity

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.

What We Would Love To Meet You If You
  • Are your own worst critic. You set a high bar for quality, ship fast, and act to fix problems rather than just voice them.
  • Have 2+ years of experience building real world applications and integrating LLMs into production systems.
  • Are exceptional at Python.
  • Can build your own tools as needed, such as a quick Streamlit app for testing hypotheses or creating a dataset.
  • Take a quantitative approach to building products, debug, experiment, and iterate fast across the full development lifecycle.
The Core Work Will Include
  • Integrating and optimizing LLM calls for structured extraction, form filling, and document understanding tasks.
  • Improving API design and preprocessing algorithms (chunking, structured extraction, etc.) based on customer feedback.
  • Building and improving document processing pipelines that handle PDFs to spreadsheets at scale.
  • Experimenting with new techniques and output structures to improve LLM accuracy and reduce latency.
  • Building internal tooling and evaluations to better understand and analyze failure cases.
  • Working directly with founders and customers to shape product direction and engineering strategy.
Bonus Points If You
  • 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, driven, and care a lot about doing great work with great people.
  • Keep up with the latest developments in ML/AI.

This is an in person role at our office in SF. We're an early stage company that requires hard work and rapid progress. Apply only if that excites you.

Benefits at Reducto
  • Unlimited PTO.
  • Daily free lunch at the office.
  • Reimbursed transportation.
  • Generous health insurance covering medical, dental, and vision.
  • Health and wellness budget up to $150/month.
  • Parental leave planning.
