What is a UI engineer?

A UI Engineer, or User Interface Engineer, is a professional who designs, develops, and implements the visual and interactive elements of software applications. They focus on creating intuitive, efficient, and visually appealing user interfaces that enhance the user experience. UI Engineers work closely with designers and backend developers to translate requirements and mockups into functional, responsive code using technologies like HTML, CSS, and JavaScript. Their role bridges the gap between design and technical implementation.

What skills and qualifications are needed to be a UI engineer?

To thrive as a UI Engineer, you need strong proficiency in HTML, CSS, JavaScript, and a solid understanding of user interface design principles, often backed by a degree in computer science or a related field. Familiarity with frameworks like React or Angular, version control systems such as Git, and design tools like Figma or Sketch is typically required. Attention to detail, creativity, and effective communication are crucial soft skills that set exceptional UI Engineers apart. These skills and qualities ensure the creation of visually appealing, user-friendly, and high-performance interfaces that meet user and business needs.

How does a UI engineer collaborate with UX designers and front-end developers during a project?

UI Engineers work closely with UX designers to translate wireframes and prototypes into interactive, visually appealing interfaces, ensuring that user experience goals are met through precise implementation. They also collaborate with front-end developers to integrate UI components with application logic, maintain code consistency, and optimize performance. Regular communication and participation in design reviews or sprint planning sessions are common, which helps ensure seamless alignment between design vision and technical execution.

What is the difference between Ui Engineer vs Front End Developer?

Front End Developers primarily focus on coding and implementing the visual and interactive elements of websites or applications. The roles overlap but differ in emphasis on design versus development tasks.

How much do UI engineers make?

UI engineers typically earn a median annual salary ranging from $70,000 to $120,000, depending on experience, location, and company size. Senior roles or those with specialized skills in front-end frameworks and design tools can command higher salaries. Compensation may also include benefits such as bonuses and stock options.

UI Engineer
Boston/NYC
OnCorps AI is the leading enterprise Agentic AI solution for middle and back-office automation. The company delivers production-ready AI agents that automate reconciliation, exception resolution, and oversight workflows for the world's largest asset managers, fund administrators and managed service providers.

Our environment values adaptability and rapid iteration, requiring a focus on creating highly modular, interchangeable UI components.
Key Responsibilities
  • Architect, develop, and maintain highly responsive, accessible, and scalable user interfaces using modern web technologies.
  • Partner directly with the OnCorps design team to evolve and govern our design system establishing best practices for component architecture and interaction design.
  • Collaborate with backend engineers to integrate frontend applications with robust middleware and backend APIs, ensuring smooth data handling, state management, and application performance.
  • Operate with a framework-agnostic mindset, applying deep expertise in core web fundamentals to build applications primarily utilizing React or Angular.
  • Help drive frontend innovation by exploring and adopting cutting-edge interaction models as we define our future agent framework.

What We're Looking For
  • 5+ years of professional experience in frontend development, UI engineering, or a related field.
  • Strong proficiency in JavaScript/TypeScript, HTML5, and modern CSS/styling methodologies.
  • Deep understanding of modern, component-driven frontend frameworks such as React or Angular, with the flexibility to adapt to the best tool for the job.
  • Proven track record of building, documenting, and maintaining robust design systems using Storybook.js or similar tools.
  • Solid experience working with middleware, RESTful/GraphQL APIs, and state management.
  • A product-focused mindset with a strong appreciation for UX/UI design principles.
  • A passion for staying ahead of the curve in frontend technology and how AI is shaping the future of user interfaces.
  • Prior exposure to middle- and/or back-office operations within the financial industry or fund administration is a plus.
