Here, you will find a culture guided by inclusion, talented peers, comprehensive benefits and career development opportunities. Come make an impact on the communities we serve as you help us advance health optimization on a global scale. Join us to start Caring. Connecting. Growing together.
We are looking for a Senior Full Stack Engineer who thrives in an AI‑first engineering culture. This role combines Python backend development, modern frontend frameworks (React/Flutter), cloud engineering on AWS, and daily use of GenAI tools to deliver high‑impact healthcare technology solutions.
AI is not experimental here - it is a core part of how we design, build, test, and operate software.
Primary Responsibilities:
Design, develop, deploy, and support enterprise‑grade full‑stack applications
Build Python‑based microservices and REST APIs at scale
Develop intuitive, high‑performance React or Flutter user interfaces
Use AI‑assisted development tools (e.g., GitHub Copilot, Codex, Microsoft 365 Copilot) as part of daily engineering workflows
Review, validate, and refine AI‑generated code to meet Optum's quality, security, and compliance standards
Architect and deploy solutions across AWS, Azure, and hybrid cloud environments
Build and maintain CI/CD pipelines and modern deployment strategies (blue‑green, canary, rolling)
Implement secure‑by‑design practices (authentication, authorization, encryption, secrets management)
Collaborate with product, UX, data, platform, and security teams
Mentor engineers and help scale AI‑assisted engineering best practices across teams
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

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.
