We are seeking a Principal AI/ML Engineer to join our Process Automation team, focused on designing and delivering intelligent automation solutions that drive operational efficiency across Optum's revenue cycle. In this role, you will work at the intersection of software engineering, robotic process automation (RPA), and apply AI translating complex business processes into scalable, maintainable automated workflows.

You don't need to arrive with RPA expertise - we provide structured training on UiPath and our automation platform. What we're looking for is a strong engineering foundation, sharp analytical thinking, and communication skills to bridge business stakeholders and technical teams effectively.

Primary Responsibilities:

• Design, build, and deploy Agentic chat workflows that will create Process Documentation and business cases for the approval to rapidly deploy RPA workflows using UiPath to automate revenue cycle and back-office business processes
• Integrate AI and machine learning capabilities into automation pipelines to handle unstructured data, decision logic, and exception handling
• Develop reusable automation components, frameworks, and libraries that accelerate delivery across the team
• Apply software engineering best practices - version control, code review, unit testing, CI/CD - to automation assets
• Collaborate with business stakeholders to understand end-to-end processes, document requirements, and identify automation opportunities
• Translate ambiguous business requirements into structured technical specifications and automation designs
• Perform process discovery and current-state analysis to evaluate feasibility, complexity, and ROI of automation candidates
• Proactively identify edge cases, failure modes, and process risks before implementation
• Serve as a bridge between business process owners and the engineering team - translating technical concepts for non-technical audiences and business context for technical teams
• Communicate project status, risks, and tradeoffs clearly and proactively to team leads and stakeholders
• Participate actively in Agile ceremonies: sprint planning, standups, retrospectives, and backlog refinement
• Collaborate closely with architects, senior developers, QA, and operations teams to deliver high-quality solutions
• Contribute to documentation including process design documents, runbooks, and knowledge base articles
• Stay current with emerging AI tooling, LLM integrations, and automation platform capabilities (UiPath, Azure AI, etc.)
• Identify opportunities to enhance existing automations with AI-driven capabilities such as intelligent document processing, NLP, and predictive analytics
• Participate in post-implementation reviews and incorporate lessons learned into future builds
• Collaborate with research, engineering, and product teams to translate cutting-edge AI advancements into production-ready capabilities. Uphold ethical AI principles by embedding fairness, transparency, and accountability throughout the model development lifecycle.
  

You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.

Required Qualifications:

• Bachelor's degree in computer science, Software Engineering, Information Systems, or equivalent experience 
• 7+ years of hands-on software engineering experience in one or more languages (Python, Java, C#, JavaScript, or equivalent)
• 7+ years of experience in writing clean, maintainable, and well-documented code
• 7+ years of experience working with APIs, data pipelines, or system integrations 

Preferred Qualifications:

• Hands-on experience with RPA platforms - UiPath strongly preferred; Automation Anywhere or Blue Prism also considered
• Exposure to AI/ML workflows, LLM integrations, or intelligent document processing (IDP)
• Experience in healthcare, revenue cycle, or regulated enterprise environments
• Familiarity with Azure cloud services, including Azure AI, Azure Functions, or Azure Data Factory
• Experience with relational databases (SQL Server, Oracle, MySQL) and/or NoSQL platforms
• Background in process improvement methodologies (Lean, Six Sigma, or similar)
• Agile development experience and familiarity with tools such as Jira, Confluence, or Azure DevOp
