## Description

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

Take the first step towards your dream career. Here is what we are looking for in this role.

AI & Modern Engineering Focus

We're actively incorporating AI-powered capabilities into our platform, and you are expected to shape how this is done responsibly and effectively in an enterprise environment. This includes:

 * Integrating and building LLMs and AI services into .NET- and Python-based systems
 * Designing and implementing AI-assisted workflows, copilots, or intelligent automation features
 * Working with agentic AI patterns (e.g., task orchestration, tool-using agents, workflow automation)
 * Applying prompt engineering, evaluation techniques, and guardrails to ensure reliability and compliance
 * Collaborating with data and platform teams to operationalize AI-not just prototype it
