Lead Product Designer

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: Curious about AI-powered tools and workflows, and use emerging technologies thoughtfully to improve speed, quality, and impact.

Nice-to-Haves

• 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.

Benefits

• Health care insurance
• 401(k) retirement account
