Principal Software Engineer

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., Our technology stack continues to evolve, but experience in areas such as the following is valuable:

• Python
• C#
• Azure (preferred), AWS, or Google Cloud Platform
• Docker
• Kubernetes
• Distributed systems
• Event-driven architectures
• Search platforms
• Vector databases
• LLMs
• Retrieval-Augmented Generation (RAG)
• Embeddings
• OCR
• Intelligent Document Processing
• Knowledge Graphs
• 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
• balancing long-term architecture with short-term execution

Most importantly, they remain hands-on.

This is a role for engineers who still love building.

• 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

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., 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., Enterprise AI is entering its next phase.

Organizations aren’t looking for chatbots-they’re looking for AI systems that can reason over their knowledge, operate responsibly, and deliver measurable business outcomes.

At UiPath, you’ll help build the platform that makes that possible.

If you’re excited by difficult engineering problems, modern AI systems, and building software that thousands of organizations rely on every day, we’d love to talk.
