Lead Product Designer

Twilio is a leading company in the communications industry, focusing on innovative solutions for businesses. They are seeking a senior-level Lead Product Designer to drive the user experience for Twilio's Voice Products, leading the design strategy for complex developer tools and ensuring seamless integration with AI capabilities.

Responsibilities:

• Lead End-to-End Voice Design: Own the complete user journey for Twilio Voice products, translating sophisticated telecom abstractions (SIP, WebRTC, real-time media streams, and turn-taking latency) into clean, logical, and delightful developer experiences
• Drive Cross-Channel Coherence: Collaborate with design peers across Messaging and Email to build an omnichannel, channel-agnostic observability and configuration narrative inside One Console
• Formulate Systems Architecture: Shape mental models, complex configuration wizards, and underlying information architectures. Champion rigorous design paradigms to navigate complex, multi-layered technical landscapes
• Design for Platform Interoperability: Partner closely with design peers across the Conversations and AI product teams to ensure Twilio Voice seamlessly integrates with advanced conversational tools (like ConversationRelay) and AI capabilities, building cohesive end-to-end user journeys where these platforms intersect
• Uphold Craft Excellence & Governance: Actively participate in, facilitate, and scale the UX Design Feedback Process, taking work from concept through formal Design Reviews and Cross-Functional Product Experience Reviews. Mentor junior designers and establish 'gold standard' craft expectations
• Partner Vertically and Horizontally: Establish a leadership-to-leadership operating model with Product Managers, Engineering Leads, and Architects to build shared roadmaps, negotiate technical constraints, and ensure high-fidelity design execution

Requirements:

• 8+ years of professional product design experience specifically focused on highly technical software products, developer tools, infrastructure, or complex B2B/SaaS platforms
• A strong, exhaustive portfolio demonstrating structural systems thinking, data-driven design decision-making, and deep individual product design craft
• Proven cross-functional influence: Demonstrated success partnering directly with engineering and product leaders to navigate organizational complexity, align cross-product touchpoints, and handle competing priorities in fast-evolving environments
• Comfort with Ambiguity: A self-starter who thrives when thrown into highly complex, loosely-defined technical spaces and is capable of building clear frameworks out of abstract constraints
• AI-Powered UX Mindset: We're building a UX team that's thoughtful about how AI is changing the way products are built, as well as how our work gets done. We expect UXers to be curious about AI-powered tools and workflows, and to use emerging technologies thoughtfully to improve speed, quality, and impact. We're looking for people who can help us evolve our practice as these tools and expectations continue to change
• Designed for Developers: Practical experience designing interfaces for technical builders (APIs, SDKs, CLIs, and configuration consoles)
• Real-Time Telemetry/Observability Experience: Prior background designing high-density data visualizations, live charts, error logging systems, or diagnostics dashboards
• Direct Engineering Fluency: Experience utilizing modern code-modification or prototyping AI tools or familiarity safely contributing directly to front-end code repositories
