Job Description

Posted on: September 10, 2025

Job DescriptionAbout Omu Omu is building an AI-native operating system for workforce value creation. Our platform combines AI copilots, agentic workflows, and modern data infrastructure to redesign workforce structures, compensation, and equity. We are early-stage, lean, and design-conscious — our demos and pilots must inspire confidence, clarity, and trust. The Role We are looking for a fractional UI/UX Designer to work closely with our CTO and founding team. This is a part-time, flexible role (estimated 20–30 hours/month) that will scale with our needs. You’ll be responsible for ensuring our product experience and public-facing materials look crisp, modern, and distinctive. You’ll design product flows, create high-fidelity mockups, and help establish a design system that engineers can build upon. In parallel, you’ll also own the design of our marketing website/landing page to ensure it communicates our vision with clarity and creativity. Responsibilities

  • Collaborate with the founding team to translate complex AI-driven workflows into intuitive, elegant user experiences.
  • Create polished product designs that are crisp, modern, and creative.
  • Help establish our design system (typography, color, components) and maintain consistency across the product.
  • Provide design polish for investor/customer-facing demos and prototypes.
  • Design and iterate on our landing website/marketing site to ensure brand consistency and impact.
  • Collaborate closely with the founding team, with flexibility to scale contributions as the company grows.

What We’re Looking For

  • 5+ years of experience in UI/UX design for SaaS or digital platforms.
  • Portfolio that demonstrates clean, modern design with distinctive character — not just cookie-cutter SaaS templates.
  • Experience designing both product UX and public-facing websites.
  • Familiarity with designing for AI-driven workflows a plus, but not required.
  • Proficiency in Figma (or equivalent) and ability to deliver ready-to-build design assets.
  • Strong communication skills; able to work effectively in a fractional, async role.

Commitment

  • Flexible, ~20–30 hours/month initially, with the potential to expand.
  • Engagement through hourly contracting or design agency-style retainer.
