What you will do

Your mission

UiPath’s Intelligence Document Processing drives understanding of the documents and messages on which a business runs: invoices, claims, contracts, customer emails. We use frontier LLMs to turn all of that into structured data that automations and AI agents can act on. You'll be building the product that does it: the ingestion and extraction pipelines, the APIs customers build their operations on top of, and the systems that make those models useful, fast and trustworthy at enterprise scale.

What you need

A solid track record (7+ years) building and operating large-scale commercial services that real customers depend on.
Strong programming ability and the confidence to pick up whatever language a problem calls for. You'll meet Python, Rust and C# here, but we don't expect you to arrive knowing them all.
Real-world experience with cloud platforms (Azure, AWS or GCP) and containerised deployment on Kubernetes. You understand how production systems get shipped, monitored and scaled, not just written.
Comfort with data at scale: SQL, and the trade-offs between different storage and search systems.
Experience working with coding agents, and opinions about them, What responsible use looks like, where they earn their keep and where they cost you, and how you keep evaluating them in an ecosystem that changes every few months.
An appreciation for tools that catch bugs before runtime — type systems, tests, and designs that make bad states unrepresentable. Especially in the age of coding agents.
A pragmatic grasp of computer science fundamentals. We care about solving real problems with the right data structure, not reciting one from a textbook.
Experience shipping LLM-backed products to production is a strong plus: prompting, evaluation, and everything else that turns a model into a feature people will trust.
Familiarity with document processing is a plus: OCR, layout, and the messy reality of documents as they actually arrive.
An opinion on what makes good code and good architecture, and the ability to argue it, including against us.
You're a builder and a problem-solver at heart.

Maybe you don’t tick all the boxes above—but still think you’d be great for the job? Go ahead, apply anyway. Please. Because we know that experience comes in all shapes and sizes—and passion can’t be learned.

Many of our roles allow for flexibility in when and where work gets done. Depending on the needs of the business and the role, the number of hybrid, office-based, and remote workers will vary from team to team. Applications are assessed on a rolling basis and there is no fixed deadline for this requisition. The application window may change depending on the volume of applications received or may close immediately if a qualified candidate is selected.
