Principal Engineer -Intelligent Document & Context Grounding

About the role

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.

Responsibilities

• 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.
• Own systems responsible for document ingestion, parsing and extraction, chunking and embedding, indexing, retrieval, knowledge management, evaluation, and answer grounding.
• Raise the quality bar for enterprise AI: Drive improvements in retrieval quality, answer quality, groundedness, attribution, latency, scalability, and cost efficiency. 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.
• Work across distributed services, event-driven architectures, search platforms, vector databases, APIs, orchestration, and cloud-native infrastructure.
• Lead through technical excellence: Actively shape architectural decisions across organizations, mentor senior engineers, participate in critical design reviews, establish engineering standards, help teams make thoughtful technical tradeoffs, and 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.

Qualifications

• 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 communication skills and the ability to explain complex technical concepts clearly
• A track record of mentoring engineers and influencing technical direction beyond their immediate team

Technologies You May Work With

Our technology stack continues to evolve, but experience in areas such as the following is valuable: Python, C#, Azure (preferred), AWS, or GCP, Docker, Kubernetes, Distributed systems, Event-driven architectures, Search platforms, Vector databases, LLMs, Retrieval-Augmented Generation (RAG), Embeddings, OCR, Intelligent Document Processing, Knowledge Graphs, and Evaluation frameworks.

What Makes Someone Successful Here

The strongest engineers on this team don't simply know AI—they know how to build AI products. They enjoy solving ambiguous technical problems, making thoughtful engineering tradeoffs, shipping production software, collaborating across disciplines, mentoring other engineers, and balancing long-term architecture with short-term execution. Most importantly, they remain hands-on. This is a role for engineers who still love building.
