AI ML Engineer

Optum AI is UnitedHealth Group's enterprise AI team. We are AI/ML scientists and engineers with deep expertise in AI/ML engineering for health care. We develop AI/ML solutions for the highest impact opportunities across UnitedHealth Group businesses including UnitedHealthcare, Optum Financial, Optum Health, Optum Insight, and Optum Rx. In addition to transforming the health care journey through responsible AI/ML innovation, our charter also includes developing and supporting an enterprise AI/ML development platform.

Optum AI team members:
• Have impact at scale: We have the data and resources to make an impact at scale. When our solutions are deployed, they have the potential to make health care system work better for everyone.

• Do ground-breaking work: Many of our current projects involve cutting edge ML, NLP and LLM techniques. Generative AI methods for working with structured and unstructured health care data are continuously being developed and improved. We are working in one of the most important frontiers of AI/ML research and development.
• Partner with world-class experts on innovative solutions: Our team members are developing novel AI/ML solutions to business challenges. In some cases, this includes the opportunity to file patents and publish papers about the methods we develop. We also collaborate with AI/ML researchers at some of the world's top universities.

Primary Responsibilities:

• Develop and deploy innovative AI solutions to various business problems. You will have the opportunity to learn and apply some of the most cutting-edge AI technologies
• Research and evaluate new data sources, AI technology trends and methodologies to enhance Organization level data science capabilities and solutions
• Designing, developing, and maintaining a robust infrastructure to seamlessly deploy, monitor, and manage machine learning models in production environments, bridging the gap between data science and IT operations by ensuring efficient and scalable model deployment and performance tracking; collaborating closely with data scientists to streamline the ML lifecycle through automation and optimization
• Comply with the terms and conditions of the employment contract, company policies and procedures, and any and all directives (such as, but not limited to, transfer and/or re-assignment to different work locations, change in teams and/or work shifts, policies in regards to flexibility of work benefits and/or work environment, alternative work arrangements, and other decisions that may arise due to the changing business environment). The Company may adopt, vary or rescind these policies and directives in its absolute discretion and without any limitation (implied or otherwise) on its ability to do so

Required Qualifications:

• Proficiency in programming/scripting languages Python with expertise in relevant ML libraries like Scikit-learn, PyTorch, SQL etc.
• A sound understanding of common NLP tasks such as text classification, entity recognition, entity extraction, and question answering
• Understanding of multiple machine learning techniques such as supervised, unsupervised, reinforcement learning, Deep learning, NLP
• Understanding of Both Opensource and Open AI LLMs and RAG architecture
• Proficiency in effective version control strategies for ML models, data, and code, along with robust logging mechanisms to facilitate debugging and auditing
• Proven ability to design and architect scalable ML systems, considering performance, reliability, and maintainability
• Proven good grasp of using LLMs, Deploying LLMs
• Proven excellent analytical and problem-solving skills, including the ability to disaggregate issues, identify root causes and recommend solutions

At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone. We believe everyone-of every race, gender, sexuality, age, location and income-deserves the opportunity to live their healthiest life. Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups and those with lower incomes. We are committed to mitigating our impact on the environment and enabling and delivering equitable care that addresses health disparities and improves health outcomes - an enterprise priority reflected in our mission.
