This role reports to the Director of Product for the Construct Platform. Key Responsibilities Design Execution Explore and visualize concepts: Translate product requirements and user needs into low-fidelity sketches, storyboards, or flow diagrams to frame early ideas and test assumptions. Iterate user experiences: Build wireframes and/or clickable prototypes to define user flows and resolve functional interactions. Develop refined design direction: Expand concepts and prototypes into detailed UX reference designs for engineering that balance usability, visual design, and technical feasibility. Deliver implementation-ready designs: Produce clear, organized design specifications and documentation for engineering handoff. Create Ai-native design system You are experienced to incorporate a set of AI-supported tools into the process (editor, coding agent, MCP/API…) to optimize and automate workflow for creating and maintaining a Design System Create modular, accessible, pixel-perfect UI components with AI tools and/or Figma that are compatible with all platforms (web, mobile, etc.). Produce detailed design specifications to guide component development, including best practices, accessibility, interaction, and visual guidelines. Work closely with developers to ensure design feasibility, quality, and consistency across all products and teams. Manage updates and ongoing improvements to the Design System in line with requirements and constraints. Support product and tech teams in adopting and using the Design System. Collaboration & Workflows Collaborate with the Senior Product Designer and Product Owners to understand design requirements, scope, and priorities. Partner with Product Managers to ensure features align with the broader product ecosystem. Collaborate with Front-end Engineering to ensure design implementation matches intent. Participate in team rituals such as sprint planning, design reviews, and retrospectives. Quality & Consistency Ensure visual and interaction quality and consistency across all product surfaces. Contribute to and maintain shared component libraries and design systems to ensure a cohesive user experience across products. Conduct basic QA on implemented designs to ensure fidelity between design and build. Communication Communicate effectively with cross-functional teams to clarify requirements and resolve implementation questions. Support the creation of design guidelines and internal documentation. What Success Looks Like (First 6–12 Months) Product features are launched with intuitive, consistent, and high-quality designs that elevate the overall user experience. Design handoffs to engineering are seamless, with minimal rework and clear documentation. The shared design system and component library are actively maintained. Collaboration with Product and Engineering is proactive, efficient, and grounded in shared understanding of goals and user needs. Qualifications Have 3+ years of experience as a Product Designer, UI Designer, UX Designer or similar role. You are a crafter with strong contributions to design system. Strong foundation in design production for mobile and web applications.
