About The Position

We’re looking for a Senior UX/UI Designer to craft intuitive, trustworthy, and human-centered experiences for our AI-driven products. You’ll work closely with product, engineering, and our business teams to translate complex AI capabilities into clear, usable interfaces. This role is ideal for someone who’s comfortable wearing multiple hats (moving fluidly between research, strategy, interaction design, and high-fidelity UI) and who thrives in an evolving environment. Please note this is a temporary-to-hire position.

Requirements

5+ years of experience in UX/UI, Product Design, or Interaction Design
A portfolio demonstrating end-to-end product work, systems design, dashboards, or AI/ML interfaces
Experience with design systems or component-based design
Fluency with modern design tools (Figma preferred) and prototyping best practices
Strong understanding of UX principles, design thinking, and how to simplify complex information
High craft in visual/UI design—clean layouts, thoughtful typography, and an eye for detail
Ability to navigate ambiguity and work autonomously while collaborating closely with cross-functional teams

Nice To Haves

Experience building or contributing to design systems
Familiarity with basic front-end concepts (HTML/CSS or React understanding is a plus)
Familiarity with A/B testing, data-driven design, and other user research methods
Motion design or prototyping skills (After Effects, Figma, ProtoPie)
Passionate about advocating for clarity, transparency, accessibility, and ethical design principles across AI surfaces

Responsibilities

Design end-to-end product experiences—from discovery and concept exploration to polished UI and developer-ready specs
Translate AI model behaviors, system feedback, and data outputs into understandable, user-friendly interactions
Build flows, wireframes, prototypes, and high-fidelity visuals that communicate complex ideas with simplicity
Collaborate with product, engineering, marketing, and business team members to define requirements and ensure responsible, user-aligned design
Document patterns and contribute to the evolution of our design system for AI-specific components (e.g., chat interfaces, generative data visualizations)
Run or support user research, usability testing, and iterative experimentation to validate and improve designs
Partner closely with engineering to deliver high-quality implementations and refine interactions post-launch
