Description

Key Responsibilities

• Design intuitive user experiences for AI-powered capabilities across web, desktop, mobile, and administrative interfaces.
• Explore new interaction models for generative AI, including conversational interfaces, copilots, AI assistants, intelligent recommendations, content generation, summarization, and AI-driven workflow automation.
• Design experiences for emerging agentic AI capabilities where AI systems can reason, recommend actions, execute tasks, and coordinate multi-step workflows on behalf of users.
• Translate complex AI functionality into simple, understandable interactions appropriate for everyday business users.
• Determine when AI should proactively assist users versus when users should explicitly initiate or control AI functionality.
• Design effective patterns for prompts, suggestions, generated content, AI actions, confirmations, feedback, and human intervention.
• Create experiences that communicate what an AI system is doing, why it made a recommendation, and what actions it has taken or intends to take.

• Own design initiatives from discovery and concept development through prototyping, implementation, launch, and post-launch optimization.
• Conduct user research, usability studies, interviews, competitive analysis, and workflow analysis to understand customer needs and behaviors.
• Translate customer problems and product requirements into user journeys, workflows, wireframes, prototypes, and high-fidelity designs.
• Develop and validate design hypotheses through rapid prototyping and user testing.
• Identify opportunities to simplify complex workflows through thoughtful UX and intelligent automation.
• Use qualitative and quantitative data to evaluate experiences and recommend improvements.
• Work closely with Product Management to ensure designs address meaningful customer problems and measurable business outcomes.

• Design AI experiences that establish appropriate levels of trust, transparency, and user control.
• Clearly distinguish AI-generated information and actions where appropriate.
• Design graceful experiences for uncertainty, incomplete information, errors, hallucinations, and situations where the AI cannot confidently complete a request.
• Create effective confirmation, undo, escalation, and human-in-the-loop patterns for AI-driven actions.
• Design feedback mechanisms that allow users to evaluate, correct, or improve AI-generated results.
• Partner with Product, Engineering, Security, Privacy, and Legal teams to incorporate responsible AI principles into the user experience.
• Help establish UX guidelines for consistent and responsible use of AI throughout Intermedia products.

• Contribute to and evolve Intermedia's design system to support AI-powered experiences.
• Define reusable patterns and components for conversational interfaces, AI recommendations, generated content, AI actions, status indicators, feedback mechanisms, and agentic workflows.
• Ensure new AI capabilities integrate naturally with established product experiences rather than feeling like disconnected features.
• Maintain consistency across products while identifying where emerging AI interactions require new design paradigms.
• Partner with designers and developers to ensure design-system components are practical, scalable, accessible, and consistently implemented.

• Partner closely with Product Managers, Product Owners, AI/ML engineers, software engineers, architects, researchers, and other designers.
• Facilitate design workshops and collaborative discovery sessions to explore customer problems and AI opportunities.
• Clearly communicate design rationale, research findings, user needs, and tradeoffs to technical and non-technical stakeholders.
• Challenge assumptions and advocate for customer-centered solutions when technology or implementation considerations begin driving the experience.
• Provide design leadership and mentorship to other designers and help raise the overall quality of UX across the organization.
• Collaborate effectively across multiple teams and product areas to create coherent end-to-end customer experiences.
• Stay current with emerging AI technologies, interaction patterns, and design practices and translate relevant developments into practical product experiences.

• 5+ years of professional UI/UX, Product Design, or Interaction Design experience, ideally designing complex SaaS or enterprise software.
• A strong portfolio demonstrating end-to-end product design, complex workflows, interaction design, and thoughtful problem solving.
• Excellent knowledge of usability, UX/UI, interaction design, information architecture, accessibility, and human factors principles.
• Strong ability to analyze complex requirements and turn them into simple, elegant solutions.
• Experience conducting or participating in user research and usability testing.
• Strong proficiency with Figma, prototyping tools, and modern design-system practices.
• Experience working closely with Product Management and Engineering in an Agile software-development environment.
• Strong communication, presentation, collaboration, and stakeholder-management skills.
• Ability to work effectively with ambiguity and rapidly evolving requirements.
• Strong attention to detail while maintaining an understanding of the broader product and customer experience.

• Experience designing products or features powered by generative AI, machine learning, or intelligent automation.
• Understanding of large language models (LLMs) and the opportunities and limitations they introduce into product experiences.
• Familiarity with conversational UX and natural-language interfaces.
• Understanding of concepts such as prompts, context, AI-generated content, confidence and uncertainty, hallucinations, and AI feedback loops.
• Familiarity with AI agents and emerging patterns for designing systems that can perform multi-step actions on behalf of users.
• Experience thinking through trust, transparency, explainability, privacy, and user control in AI experiences.
• A strong interest in experimenting with new AI tools and interaction models.

• Experience designing enterprise communications, collaboration, contact center, productivity, or workflow-automation products.
• Experience designing AI copilots, assistants, conversational interfaces, or agentic workflows.
• Experience developing or contributing to large-scale design systems.
• Experience with voice and multimodal interfaces.
• Understanding of accessibility standards and inclusive design.
• Familiarity with HTML/CSS and the technical constraints of modern web applications.
• Experience using AI-assisted design and prototyping tools.
• Experience working with globally distributed Product and Engineering teams.

• Customers immediately understand how AI can help them.
• Complex AI capabilities feel simple and natural to use.
• Users remain informed and in control when AI recommends or takes actions.
• AI features integrate seamlessly into existing customer workflows.
• Common AI interaction patterns become consistent across Intermedia products.
• Research and customer feedback meaningfully influence AI product decisions.
• Product and Engineering teams view Design as a strategic partner in determining what AI experiences should be built, not simply how they should look.
