• Apply front-end security best practices for applications handling PHI, including OAuth 2.0/OIDC authentication flows, secure session handling, XSS prevention, and Content Security Policy
• Champion responsive, cross-browser UI development with modern CSS and a consistent component library
• Contribute to front-end architecture at scale (such as micro-frontends) and front-end CI/CD, including automated builds, linting, and deployment
• Design, develop, and maintain back-end services and GraphQL APIs that power the front end
• Implement serverless architectures and microservices that are independently scalable, resilient, and easy to deploy
• Integrate and customize rules engines for automated decision-making and efficiency
• Ensure application security and compliance with HIPAA and other regulations, with a focus on performance and scalability
• Engage with Product, UX, and cross-functional teams to define and deliver features that meet the complex demands of the healthcare sector
• Mentor engineers on front-end architecture, code quality, accessibility, and testing through code reviews, pairing, and technical guidance
