Chunkr is an open-source API service for converting complex documents into LLM/RAG-ready data. We're building the essential vision infrastructure layer for AI developers creating standout applications.

Founded by three self-taught developers, we value agency, perseverance, and the power of open source. We serve AI teams from seed-stage startups to enterprises across verticals like finance, healthcare, gov-tech, manufacturing, e-comm, and dev-tools - where accurate and fast document processing is critical!

What You’ll Do

As an Intern, you will contribute directly to our core product and ecosystem:

• Develop and maintain SDKs and internal tools (TypeScript, Python, Rust).
• Enhance our React-based front-end application and user experience.
• Engage with the community via PR’ing Chunkr into other open-source dev tools.
• Build data pipelines for collecting, cleaning, and preparing document data to train CV & specialized small Vision Language Models (VLMs).
• Create technical documentation, usage guides/cookbooks, and blog posts to empower developers.
• Jump into wildfires - tasks like enterprise customer deployment support, or optimizing inference code. Expect curveballs; swing hard.

What We’re Looking For

• Demonstrated ability to ship software, showcased through a portfolio (GitHub, personal projects, deployed applications).
• Proficiency in TypeScript + React, and Python. Rust experience is a significant plus.
• Strong technical writing and communication skills (examples like blogs/sharing your work online highly valued).
• Familiarity with LLM/VLM APIs, chunking/embedding techniques, and RAG concepts.
• An interest in document intelligence challenges (e.g., layout analysis, table extraction, OCR).
• Self-starters comfortable in a fast-paced, small-team environment. Prior startup or OSS contribution experience is beneficial.

Our Momentum

Processing millions of pages daily for a diverse customer base.
