• Build and tune Db2 for iseries database objects and access paths; manage referential integrity, journaling, and commitment control
• Execute full SDLC: requirements, estimation, technical design, unit/integration testing, code reviews, and deployments via change-management tools
• Collaborate with BAs, QA, and stakeholders in Agile ceremonies
• Use AI tools to accelerate work: generate/refactor action diagrams and code snippets, analyze logs/SQL plans, draft tests and documentation-validating outputs and following privacy/compliance guidelines
• Optional domain: support pharmacy claims/RxCLAIM interfaces, extracts, and operational workflows

• Knowledge of security and compliance practices on IBM i (object authority, adopted authority, auditing) and working within HIPAA-compliant environments
• AI fluency: hands-on use of AI-assisted development and support tools (e.g., GitHub Copilot/CodeWhisperer and chat-based assistants) to improve productivity; skill in prompt creation, validating AI outputs, and applying privacy/compliance best practices when using AI
• Domain plus: RxCLAIM experience preferred; understanding of PBM/pharmacy claims concepts (NCPDP D.0, eligibility, accumulators, pricing) and related EDI standards (270/271, 834, 835)

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.
