AI UI Developer

UI Developer - Agentic ERP Platform

The UI Developer is responsible for building the front-end interfaces of Rimini Street's Agentic ERP Platform—the approval workflows, real-time agent activity views, explainability surfaces, and configuration screens that enable users to supervise, guide, and intervene in AI agent actions. This role owns the human-in-the-loop experience, ensuring users can review and accept or reject agent-proposed actions before they reach downstream ERP systems, trace any agent decision back to its reasoning chain, and configure agent policies and escalation rules.

Reporting to the VP, Platform Engineering, this developer designs and implements the Angular-based front end, working closely with backend engineers and UX stakeholders to deliver production-quality interfaces. The ideal candidate is a strong Angular developer with experience building complex, data-rich applications and an interest in AI-powered user experiences where real-time streaming and intervention patterns are core requirements.

Essential Duties & Responsibilities

• Build approval workflow interfaces where users review, accept, or reject agent-proposed actions before they execute against ERP systems.
• Implement time-bound approval patterns that handle long-running workflows, including deferred actions and bulk approval scenarios.
• Develop real-time agent activity streams showing what agents are doing, their reasoning, and pending actions.
• Build notification and alerting interfaces for escalations, policy violations, and actions requiring human intervention.

• Build explainability views that let users trace any agent action back to its decision chain, tool calls, policy evaluations, and confidence scores.
• Implement audit trail interfaces that provide full visibility into agent session history and outcomes.
• Develop dashboard views and data visualizations that surface platform health, agent performance, and operational metrics.

• Build and maintain the platform's Angular-based front-end application, delivering responsive and accessible interfaces.
• Develop policy and configuration surfaces for RBAC roles, agent guardrails, and escalation rules.
• Integrate front-end components with backend REST APIs and real-time data streams via WebSocket and Server-Sent Events.
• Implement state management patterns for complex, multi-pane applications with concurrent agent activity.
• Handle authentication and authorization flows in the UI layer.

• Write clean, maintainable, and well-tested TypeScript/Angular code.
• Build and maintain the platform's design system and component library with documented usage patterns.
• Participate in code reviews and contribute to front-end architecture decisions.
• Ensure accessibility compliance (WCAG 2.1 AA) across all platform interfaces.
• Optimize front-end performance: lazy loading, efficient rendering, and minimal bundle sizes.

Experience

• 5+ years of front-end development experience, with at least 2 years building Angular applications (Angular 14+).
• Proven experience building complex, data-rich web applications in production.
• Experience with component-based architecture and design system implementation.
• Hands-on experience with real-time data handling (WebSockets, Server-Sent Events).
• Experience with responsive design and cross-browser compatibility.
• Enterprise software or B2B platform experience preferred.

Technical Skills

Required

• Angular 14+ with strong TypeScript fundamentals.
• HTML5, CSS3/SCSS, and responsive design techniques.
• RxJS for reactive programming and state management.
• State management at scale: NgRx, Angular signal stores, or equivalent for complex multi-view applications.
• WebSocket and Server-Sent Events for real-time UI updates and agent activity streaming.
• RESTful API consumption and client patterns.
• Component-based architecture and module design.
• Git version control and CI/CD integration for front-end builds.
• Unit testing: Jasmine/Karma or Jest for Angular applications.
• Accessibility standards (WCAG 2.1 AA) and semantic HTML.

Preferred

• Experience with data visualization libraries (D3.js, Chart.js, or AG Grid).
• Angular signals (Angular 17+) and modern reactive primitives.
• Experience designing UI for AI agents, copilots, or human-in-the-loop systems.
• Knowledge of web performance optimization (Lighthouse, Core Web Vitals).
• Experience with Angular Material or custom design system construction.
• Experience with Storybook or similar component documentation tools.

Skills & Competencies

• Strong eye for detail and commitment to delivering polished, production-quality interfaces.
• User-centric mindset; thinks about how users interact with AI-driven systems and simplifies complex workflows.
• Collaborative; works effectively with backend engineers, designers, and product stakeholders.
• Problem solver who can debug complex front-end issues across browser environments.
• Clear communicator; able to discuss technical trade-offs with both engineering and non-technical teams.
• Self-motivated and effective in a remote environment.
• Fluent in English (written and verbal).

Desired Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or related field.
• Experience in enterprise software companies or B2B SaaS platforms.
• Portfolio or examples of complex Angular applications built in production.
• Contributions to open-source front-end projects or libraries.
