Company Description
At Datalab, we train state-of-the-art language models that read documents with human-level accuracy and power the next generation of AI products, workflows, and research.
Our models - Chandra, Surya, and Marker - have become the backbone of document intelligence, with more than 50,000 GitHub stars and adoption across top tier 1 AI research labs, Fortune 500 enterprises, and government agencies.
We've grown to 7-figure ARR with ~7x growth in 2025, driven by a lean, senior team that operates with high autonomy and deep technical ownership.
Backed by founding members of OpenAI, FAIR, and Hugging Face. We move fast, ship often, and we're hiring builders who do the same.
Role Description
We’re looking for a fullstack engineer who wants to build the interfaces, tools, and infrastructure that help thousands of developers and enterprises use our models. You’ll work across the stack to shape how people interact with OCR, extraction, and document-understanding systems. That includes building core inference workflows, creating intuitive UI for complex parsing tasks, and improving the developer experience across our open-source repos and API.
This is a high-ownership role that blends engineering, product thinking, and community engagement. You will work closely with the founders and the rest of the team to ship features, improve performance, and make our technology accessible to a global community of builders.
As a small and fast-moving team, roles are fluid. You should enjoy working across backend, frontend, performance, and user-facing surfaces. Your work will directly influence how thousands of teams evaluate and deploy our models.
Day to day, you will:
- Ship features to our open source repos, API, and internal tooling
- Design and build frontend features that make document parsing more interactive and understandable.
- Optimize inference performance and improve the reliability of our frameworks.
- Engage with the community on Github and Discord by collecting feedback, debugging issues, and identifying opportunities for improvement.
- Work directly with customers on POCs, offer demos, and support implementation and ongoing usage of the platform.
Ideal Candidate
You thrive at the intersection of engineering, product, and user experience. You like working close to real users and making technical systems feel simple and intuitive. You operate with autonomy and ownership and enjoy moving quickly in an environment where you can directly influence outcomes.
We’re eager to work with someone who has:
- 5+ years of fullstack development experience building APIs and/or developer-focused products.
- Experience building in early-stage startup environments.
- Shipped a meaningful product to production, supporting thousands of active users.
- Proven experience engaging with customers for feedback and iteration.
Bonus points if you:
- Have open source contributions or maintainers experience.
- Have worked with document processing or developer tools.
- Are interested in AI and training models (prior experience not necessary)
- Enjoy writing technical content or demos to showcase your work.
