Sr. User Experience Designer

Design intuitive, business-focused voice experiences for AppFolio's AI-driven solutions, collaborating with cross-functional teams.

Responsibilities

• Lead the design of voice AI experiences, from early exploration to polished conversational flows, ensuring interactions feel intuitive and aligned with business needs.
• Help define and evolve conversational design guidelines and patterns within the broader design system.
• Collaborate with Engineering and Product Management, together with the rest of the UX Team, to ensure a consistent and high-quality user experience across complex workflows being worked on individually by many small, fast-moving, cross-functional teams.
• Develop conversation models, personas, and scripts that balance clarity, efficiency, and brand voice.
• Participate in executing a comprehensive Design Strategy, and work towards meeting usability benchmarks and KPIs.
• Collaborate with Product Management on roadmap and strategy, working as a tireless advocate for the end user and helping to balance those needs with those of the business.
• Meet complex design challenges by participating alongside engineering, QA and product in LeanUX-inspired activities such as design studios, provisional personas and storymapping.
• Ongoing, close collaboration with team members during the sprint including impromptu discussions and brainstorming activities as well as pairing with engineers on design.
• Support designers and teams as needed with wireframes, flow diagrams, rapid prototypes and visual design to help communicate and validate design ideas.
• Facilitate user research, in collaboration with the team, to test prototypes and conduct ongoing usability testing specific to conversational interfaces.
• Evangelize a cohesive user experience via the consistent use of UI patterns.
• Inspire teams beyond good usability to user delight exploring how tone, pacing, and micro-interactions in voice design can strengthen trust and engagement.
• Participate in and help drive a comprehensive Design Strategy, setting usability benchmarks and success measures for conversational products.

Requirements

• Strong portfolio of UX work with a focus on voice interfaces, conversational AI, or multimodal experiences.
• Experience designing natural, human-centered conversations — including turn-taking, error recovery, and edge cases.
• Understanding of voice UI usability principles (e.g., brevity, clarity, cognitive load).
• Basic knowledge of speech technologies (NLU/NLP, TTS, ASR) and how they shape the design process.
• Understanding of cross-channel experiences (voice, text, web, and mobile) and how to create continuity across them.
• Awareness of human-in-the-loop patterns — when to keep a person in the workflow, when to automate, and how to design smooth handoffs.
• Some background or exposure to large language models (LLMs) and emerging multimodal capabilities.
• Working knowledge of accessibility standards for voice and multimodal interfaces.
• Experience with a variety of UX deliverables (wireframes, user flows, mockups, prototypes, etc.), but with a keen sense of when to choose the right tool(s) to communicate the design.
• Knowledge of Agile UX and Lean UX methodologies and experience working in a highly collaborative environment.
• Demonstrated proficiency in low-fidelity design tools (such as FigJam) and advanced knowledge of design prototyping tools (such as Figma).
• Excellent communication and facilitation skills — able to bring clarity to ambiguous problems and rally stakeholders around the voice experience.
• Minimum of 5 years of experience in user experience-focused roles, with at least 2 years in voice/conversational design or a closely related area.

Key Skills

• Fluency in low-fidelity design tools (such as FigJam)
• Advanced knowledge of design prototyping tools (such as Figma)
