🚀 Role Summary

• Spearhead the design of a groundbreaking AI Agent platform, focusing on conversational user experiences for small to medium-sized businesses (SMBs).

• Craft intuitive, elegant, and efficient interfaces that simplify complex business logic within an intelligent assistant ecosystem.

• Drive user-centric design principles across a next-generation, web-based platform, ensuring a seamless and engaging user journey.

• Collaborate closely with engineering, product management, and stakeholders to translate requirements into high-fidelity, production-ready designs.

📝 Enhancement Note: This role is positioned at a senior level within the design function, indicating significant autonomy and influence over the product's user experience. The emphasis on "AI Agent Conversational Experience" suggests a specialized focus within UX, requiring an understanding of how users interact with AI-driven systems, not just traditional UIs. The target audience of SMBs implies a need for designs that are accessible, efficient, and solve practical business problems.

📈 Primary Responsibilities

• Conceptualize and Design User Journeys: Define and refine end-to-end user journeys for the AI Agent platform, prioritizing enhanced usability, automated workflows, and overall user satisfaction.

• Develop Rapid Prototypes and High-Fidelity Mockups: Translate abstract ideas and technical requirements into tangible, interactive prototypes and detailed, high-fidelity mockups to facilitate rapid iteration and stakeholder alignment.

• Execute UI/UX Interface Design: Create visually appealing, functional, and accessible user interfaces for a complex, web-based platform, ensuring consistency and adherence to brand guidelines.

• Foster Cross-Functional Collaboration: Actively partner with product managers, engineers, and other stakeholders to ensure design feasibility, provide clear design documentation, and contribute to agile sprint planning.

• Conduct User Research and Usability Testing: Plan and execute usability tests, gather qualitative and quantitative user feedback, and iterate on designs based on insights derived from user behavior and testing outcomes.

• Contribute to and Maintain Design Systems: Develop, document, and maintain components within the design system to ensure design consistency, accelerate development, and promote a unified design language across the product suite.

• Integrate AI and Agentic Workflow Concepts: Apply a strong understanding of modern trends in automation, AI, and multi-agent system workflows to inform design decisions and enhance the platform's intelligence and efficiency.

📝 Enhancement Note: The responsibilities highlight a blend of strategic design thinking (user journeys, AI workflows) and tactical execution (prototyping, UI design, design systems). The emphasis on "automated workflows" and "streamlined" processes points towards a need for design solutions that drive operational efficiency for the end-user, a key characteristic of roles within Sales Operations or Revenue Operations enablement, even though this is a UX role.

🎓 Skills & Qualifications

Education: While no specific degree is listed, a Bachelor's or Master's degree in Design, Human-Computer Interaction (HCI), Computer Science, or a related field is typically expected for senior roles. Equivalent practical experience will also be considered.

Experience: Over 5 years of progressive experience in User Experience (UX) design, User Interface (UI) design, and product design, with a demonstrated focus on complex, modern digital products and web applications.

Required Skills:

• Advanced UX/UI Design: Proven expertise in user-centered design methodologies, information architecture, wireframing, and interactive prototyping.

• Complex Web Application Design: A strong portfolio showcasing experience designing feature-rich, functional, and visually engaging web-based applications beyond simple marketing sites.
