Overview:

We are seeking a Senior Software UX/UI Engineer to join HR Acuity's engineering organization, focusing on front-end development. This is a long-term position, replacing an existing contractor, with opportunities for future growth into a UI leadership role. The primary responsibility is to modernize our legacy UI by transitioning from jQuery-based components to a React-based application, emphasizing performance, user experience, and maintainability.

Responsibilities:

  • Lead the redesign and development of responsive, intuitive user interfaces using React, HTML5, CSS, and Material UI (MUI).
  • Rewrite existing ASP.NET and jQuery-based UI components into a modern React-based application, dedicating ~70-80% of time to new development and ~20-30% to maintaining legacy systems.
  • Independently design and implement UI projects, collaborating across teams (modernization and experience teams) on project-based assignments.
  • Contribute to and maintain a shared UI library, ensuring consistent and scalable design across the organization.
  • Collaborate with product and design teams to translate requirements, wireframes, and mockups into functional components aligned with product goals.
  • Optimize UI components for performance, accessibility, and cross-browser compatibility.
  • Implement AJAX calls and ensure seamless integration with RESTful APIs and backend services.
  • Participate in agile development processes, including sprint planning, daily stand-ups, and retrospectives.
  • Perform code reviews to uphold coding standards and best practices.
  • Test components across multiple web browsers to ensure consistent user experiences.

Qualifications:

Required:

  • 3-5 years of professional UI/UX development experience, with a strong emphasis on React, HTML5, CSS, and JavaScript (ES6+).
  • Proficiency in Material UI (MUI), Storybook, and responsive design principles.
  • Experience with API communication, AJAX calls, and integrating modern and legacy JavaScript technologies.
  • Strong troubleshooting and performance optimization skills.
  • Ability to work independently, manage time effectively, and handle project-based assignments across multiple teams.
  • Clear and professional communication skills, with the ability to collaborate effectively in a team environment.

Preferred:

  • Familiarity with legacy systems, including jQuery and ASP.NET.
  • Experience with test automation frameworks (Playwright, Jest, Enzyme).
  • Knowledge of server-side rendering frameworks (Next.js, Gatsby).
  • Experience with containerization and deployment tools (Docker, Kubernetes).
  • Strong potential for leadership, with aspirations to grow into a UI leadership role.
