About eClinical Solutions

eClinical Solutions is transforming clinical development with elluminate®, our Clinical Data Cloud, helping life sciences organizations unify, analyze, and unlock the value of their data faster than ever before. By combining a modern cloud platform with expert data services, we empower smarter decisions across the clinical trial lifecycle—accelerating innovation that ultimately improves patient outcomes.

Our engineering teams build enterprise-grade, revenue-generating products at the intersection of cloud, data, analytics, and emerging AI technologies. If you're excited about building sophisticated software that makes a real-world impact on healthcare, this is the place to do it.

You will make an impact:

As a Senior Front-End / UI Software Engineer, you will be a technical leader within the elluminate Product Development team. You'll help design and build the core services and user experiences of a next-generation clinical data and analytics platform—while influencing architecture, engineering standards, and technical direction.

You will lead the design and development of user-centric experiences across our clinical data and analytics platform, helping define front-end standards, UI architecture, component strategy, and overall user experience quality. This role is ideal for an experienced engineer who combines deep front-end technical expertise with strong product thinking and a passion for delivering polished, performant applications.

This role is ideal for an experienced engineer who enjoys hands-on development, mentoring others, and bringing modern capabilities—including AI-assisted and agentic workflows—into production-grade systems.

Your day to day:

• Design, develop, test, and maintain modern web applications using Angular, Blazor, TypeScript, C#, HTML, and CSS
• Contribute to the modernization of existing UI applications and migration toward modern component-based architectures
• Build reusable UI components, shared libraries, and scalable front-end patterns across Angular and Blazor applications
• Collaborate with UX/UI designers to implement intuitive and responsive user experiences
• Partner with backend engineering teams to integrate APIs and distributed services into seamless UI workflows
• Optimize applications for performance, accessibility, responsiveness, and cross-browser compatibility
• Participate in architecture discussions, technical design reviews, and modernization initiatives
• Troubleshoot and resolve UI defects, performance bottlenecks, and integration issues
• Contribute to CI/CD processes, automated testing, and engineering best practices
• Mentor junior engineers and contribute to a collaborative engineering culture

Create and maintain technical documentation related to UI architecture and implementation
