Location: This is an onsite role based at Nextiva’s Scottsdale headquarters (9451 E. Via de Ventura, Scottsdale, AZ 85256).

At Nextiva, we're building the future of customer experience through thoughtful, AI-native product design. As a Senior Product Designer, you'll shape experiences across our Unified Customer Experience platform, partnering closely with Product and Engineering to solve complex customer problems through modern design, rapid prototyping, and intelligent AI-assisted workflows. This is more than a traditional design role. You'll help define product direction, challenge assumptions, and turn ideas into production-ready experiences across desktop and mobile. If you're energized by moving quickly, embracing new AI technologies, and designing products that make a measurable impact, you'll thrive here. What You'll Do: Lead end-to-end product design from discovery through delivery across desktop, mobile, and responsive experiences. Partner with Product Managers and Engineers as a strategic thought partner, challenging assumptions, asking the right questions, and helping define the best solution instead of simply executing requirements. Engage directly with customers to understand their needs, ask thoughtful questions, gather feedback, and translate insights into product decisions and improved experiences. Create user flows, customer journeys, wireframes, interactive prototypes, high-fidelity designs, and production-ready experiences across desktop and mobile. Design across multiple product domains, including onboarding, e-commerce, AI-powered product capabilities, administration, customer conversations, and emerging platform initiatives as priorities evolve. Build functional, high-fidelity prototypes using AI-assisted development workflows to validate ideas with customers and stakeholders quickly, learn from feedback, and iterate toward the right solution. Collaborate closely with Engineering by reviewing AI-generated frontend implementations, refining production code, and helping bridge design and development. Drive consistency across products by evolving and contributing to Nextiva's design system, reusable components (A2UI), and design standards. Use customer research, analytics, experimentation, and usability testing to continuously improve product experiences and business outcomes. Communicate design thinking clearly and confidently, presenting concepts, facilitating customer and stakeholder conversations, and explaining the rationale, tradeoffs, and customer insights behind design decisions. Work independently in a fast-paced environment, managing multiple initiatives while adapting quickly as business priorities evolve. Leverage AI-powered design, research, and development tools responsibly to improve speed, quality, creativity, and execution. Explore emerging AI technologies and workflows,…
