## Description

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 PDF processing pipelines (extraction, transformation, storage and delivery at scale).
-   Experience with LLM-based document processing or ML pipelines for extracting structured data from unstructured text.
-   Large scale web crawling and scraping.

## Benefits

-   Base compensation **€60,000–€90,000** based on the level of your experience
