Principal Engineer -Intelligent Document & Context Grounding

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? Principal Software Engineer – Intelligent Document Processing & Context Grounding Build the AI platform that powers trustworthy enterprise agents. At UiPath, we're building the next generation of enterprise AI—agents that don't just generate responses, but understand business context, reason over enterprise knowledge, and deliver trustworthy outcomes at scale. As a Principal Software Engineer, you'll help define and build the Intelligent Document Processing and Context Grounding platforms. Your work will enable AI agents to ingest, understand, retrieve, and reason over large volumes of enterprise documents while maintaining accuracy, security, governance, and performance. This is a hands-on engineering leadership role for someone who has repeatedly shipped production AI systems and enjoys solving some of the hardest infrastructure challenges in enterprise software. You'll influence technical direction across multiple teams while remaining deeply involved in architecture, implementation, mentoring, and product delivery. What You'll Do Build production AI systems Design and deliver the core services that power enterprise document understanding, retrieval, knowledge grounding, and Retrieval-Augmented Generation (RAG) across the UiPath platform. You'll own systems responsible for: - document ingestion - parsing and extraction - chunking and embedding - indexing - retrieval - knowledge management - evaluation - answer grounding Raise the quality bar for enterprise AI Drive improvements in: - retrieval quality - answer quality - groundedness - attribution - latency - scalability - cost efficiency You'll evaluate emerging techniques, challenge assumptions, and introduce better architectural approaches as AI capabilities continue to evolve. Solve difficult distributed systems problems Architect highly available, multi-tenant cloud services that process enormous volumes of enterprise content while maintaining reliability, security, and performance. You'll work across: - distributed services - event-driven architectures - search platforms - vector databases - APIs - orchestration - cloud-native infrastructure Lead through technical excellence Principal Engineers at UiPath don't simply review designs—they actively shape them. You'll: - influence architectural decisions across organizations - mentor senior engineers - participate in critical design reviews - establish engineering standards - help teams make thoughtful technical tradeoffs - raise the quality of engineering across the organization Partner across Engineering, Product, and Applied AI Work closely with Product Managers, Applied Scientists, Designers, and Engineering Leaders to turn ambiguous AI opportunities into production capabilities customers rely on every day. What We're Looking For We're looking for builders. Engineers who enjoy taking complex problems, designing elegant systems, and shipping software that customers depend upon. Successful candidates will typically have: - 10+ years building large-scale software systems - Significant experience shipping production AI products - Strong backend engineering experience in Python and/or C# - Deep understanding of distributed systems and cloud-native architectures - Experience building scalable APIs, microservices, and event-driven systems - Strong understanding of modern retrieval systems including RAG, embeddings, vector search, evaluation, and LLM-powered applications - Experience designing reliable, multi-tenant enterprise platforms - Excellent communica…
