Principal Software Engineer

Job description

Life at UiPath The people at UiPath believe in the transformative power of automation to change how the world works. We’re committed to creating category-leading enterprise software that unleashes that power. To make that happen, we need people who are curious, self-propelled, generous, and genuine. People who love being part of a fast-moving, fast-thinking growth company. And people who care—about each other, about UiPath, and about our larger purpose. Could that be you? 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. Increasingly that work is agentic. What you build is what lets AI agents ingest, understand, retrieve and reason over enterprise documents at volume, without giving up accuracy, security or governance. It's a product engineering role with complex systems and LLM-in-production problems underneath it. The same service handles a customer's first ten documents and another's ten million, runs in our cloud and inside a bank's own air-gapped datacentre, and has to be good enough that a business will act on its output. Knowing how well the models are actually doing, and what to do when the answer is "not well enough", is a large part of the job. You'll write in several languages here, and pick up new ones as the problem demands. We care much more about how you think than about what you've written it in. We're looking for someone who loves building things, learns fast, and wants to own product outcomes rather than tickets. What you'll do at UiPath Work with engineers, product managers and customers to design, build and operate the AI systems behind UiPath's document processing products. Build across the pipeline: ingestion, parsing and extraction, indexing and retrieval, and the evaluation that tells us any of it is working. Take features from idea to production and stay with them, measuring whether they actually worked, and improving them when they didn't. Solve genuinely hard problems in concurre…
