About Us
We're scaling rapidly and have a growing pipeline of opportunities that demand exceptional talent across disciplines. Our mission is to bring on individuals, from creative producers to technical experts to entrepreneurial leaders, who can help us realize this next chapter of growth.

Location: Remote (U.S.)
Department: Product & Design
Employment Type: Full-Time

Role Overview

The Senior UI/UX Designer will lead end-to-end product and web experience design across research, strategy, interaction, and visual execution. You'll collaborate with product, engineering, and marketing to solve complex problems, elevate usability, ship production-ready interfaces, and steward our brand and design system. This role suits a craft-obsessed designer who moves from insight to elegant, shippable UI—and communicates clearly with technical and non‑technical partners.

Responsibilities

• Product & Experience Design: Own information architecture, interaction design, and UI for client websites and web apps; design detailed user flows, wireframes, and high-fidelity interfaces for testing and developer handoff; create, test, and refine prototypes of varying fidelity; partner with engineering to visually QA UI through implementation.
• Website Design & Delivery: Lead end-to-end website experiences (marketing and product/microsites): structure, UX, responsive UI, basic knowledge of SEO and web performance, and accessibility.
• Brand & Design Language Systems: Translate brand strategy into systematized UI: typography, color, grids, motion, and component patterns; maintain and evolve our design system and documentation to ensure consistency across products and web.
• Research & UX Strategy: Plan and conduct interviews, surveys, and usability tests; synthesize insights into clear problem statements, opportunity areas, and prioritized roadmaps; define success metrics and incorporate findings into iterative design cycles; take research, raw information, and organize it into client-facing presentations, decks, and create clear stories to walk clients through findings with recommendations.
• Cross‑Functional Collaboration: Work with product, engineering, and client-facing teams to define objectives, user journeys, and visual specs; communicate design vision and product strategy across the organization; take ownership of systems; champion accessible, performant, and customer-obsessed design.

Experience & Qualifications

• 5+ years of experience combining solid visual (UI) and experience (UX) design skills.
• Online portfolio showing experience designing consumer-facing experiences for web and mobile.
• Expert-level proficiency with the Figma suite (Design, FigJam, Slides, Make), modern prototyping tools and Adobe Creative Cloud.
• Experience creating, managing, and evolving design‑systems.
• Proven ability in UX thinking and research; committed to solving real user problems and delivering intuitive, accessible experiences.
• Strong knowledge of user‑centric design principles along with web and mobile design standards and best practices.
• Basic familiarity with Webflow and web languages (HTML, CSS, JavaScript), and an understanding of modern front-end frameworks (e.g., React, Tailwind) to collaborate with engineers on integration and release.
• Experience working in agile, cross‑functional teams.
• Strong communication and collaboration skills in English.
• Bonus: startup experience; knowledge of SEO basics, web optimization, and accessibility standards; curiosity about GenAI and how to incorporate it into design workflows; experience mentoring other designers or establishing team processes.
