Principal Engineer - Intelligent Document & Context Grounding

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 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

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.

Why Join UiPath?

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.
