Paperpile runs on data at scale, with a literature database of 250M+ academic papers and a growing body of user data accumulated over more than a decade. You’ll work across the systems that ingest, process, store, and serve this data reliably: building pipelines, optimizing search, handling PDFs at scale, and exposing clean APIs.
Requirements
•
Strong backend engineering background with experience building and operating data-heavy systems in production.
•
Experience deploying and operating services on AWS.
•
Experience designing and maintaining data ingestion pipelines handling messy, heterogeneous sources. Comfortable with web scraping and working with third-party data sources and APIs.
•
Familiarity with Node.js and TypeScript. It’s fine if you come from a different background, such as Java or Python, but you should be comfortable working in this environment.
•
High standards for data quality. You think carefully about correctness, deduplication, and consistency.

Solid understanding of full-text search systems including indexing strategy, relevance tuning, and query optimization.
•
Proficient in building reliable REST APIs.
More useful experience:
•
Familiarity with academic publishing formats and data sources (PubMed, Crossref, arXiv…)

•
Experience with LLM-based document processing or ML pipelines for extracting structured data from unstructured text.
•
Large scale web crawling and scraping.
