- Optimize application performance, bundle size, and Core Web Vitals across a wide range of devices and browsers;
- Diagnose and troubleshoot bugs, UI defects, and performance issues in existing applications;
- Write unit, integration, and end-to-end automated tests (Jest, React Testing Library, and Cypress) to ensure code quality and reliability;
- Participate in code reviews, sprint planning, and agile ceremonies; collaborate closely with product managers, UX designers, backend engineers, and QA;

- Solid understanding of responsive design and cross-browser compatibility.
Additional Comments:
- Prior experience in healthcare, life sciences, pharma, or clinical research technology (e.g., eCOA, CTMS, and EDC systems);
- Familiarity with data-privacy and compliance considerations (HIPAA, GxP, and 21 CFR Part 11);
- Strong communication skills and ability to translate business/clinical requirements into technical solutions;
