• Ensure the entire platform and its products are built on the latest open standards (OAuth2, OIDC, FIDO) and privacy-by-design principles
• Lead the technical evolution of the platform to support secure healthcare data interoperability, minimizing user friction for "good" users while maximizing threat protection
• Proactively identify and mitigate emerging means of abuse by integrating advanced fraud prevention directly into the core architecture

• Hands-on experience with cloud platforms (Azure, AWS, or GCP) and microservices-based architectures
• Experience leveraging AI/ML tools or automation platforms to enhance engineering productivity and system resilience
• Deep expertise in identity and access management (IAM), authentication/authorization protocols (OAuth2, OIDC, SAML), and modern passwordless standards such as FIDO
• Solid understanding of cybersecurity principles, fraud prevention strategies, and privacy-by-design frameworks

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.
