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).

• An interest in document intelligence challenges (e.g., layout analysis, table extraction, OCR).

Compensation : $70K - $120K

About Chunkr

From papyrus to PDFs, documents have shaped industries and defined how we work - yet this wealth of information is locked within unstructured formats, beyond the reach of modern software.

As the world transitions to an AI-native future, Chunkr is building the essential vision infrastructure for developers to unlock documents for AI. We leverage traditional computer vision, vision-language models, custom tooling, and swathes of last-mile engineering. Our goal is to enable LLMs to interact with documents with the same nuance and understanding as a human!

Founded by three self-taught developers, we value agency, grit, and open source. Chunkr supports teams from seed-stage startups to enterprises in finance, healthcare, gov-tech, manufacturing, e-commerce, and dev-tools—all relying on fast, reliable document intelligence.

Our Momentum

• Processing millions of pages every day for a diverse customer base

• Running in production at both startups and large enterprises

• Delivering accurate, high-speed OCR, layout analysis, and semantic chunking

• Backed by Y-Combinator, Jack Altman (Alt Capital), and Evan Conrad (SF Compute)

Join us to build the go-to document intelligence platform!
