UI/UX Designer — Figma & React Design Systems

Operating Systems Inc. (OSI) is building a modern engineering software platform that supports the marine, offshore, and structural engineering industries. This UI/UX Designer role centers on turning design intent into production-ready React frontends, with strong emphasis on Figma and design system thinking.

Working in a hybrid setup in Spring, TX 77389 on a contract basis, you will move quickly from business requirements to high-fidelity prototypes, help stakeholders review the work, and connect Figma components and tokens to a scalable React component library.

Role focus

• Figma to production React: bridge design to production React/TypeScript frontends.
• Design systems approach: think in reusable components, variants, and tokens rather than one-off screens.
• Technical UI orientation: support complex, data-dense interfaces aligned with engineering workflows.

Responsibilities

• Operate as a UI/UX Designer who is deeply proficient in Figma and experienced in bridging design to production React frontends.
• Translate business requirements quickly into high-fidelity prototypes.
• Apply design system thinking to interfaces, not isolated layouts.
• Understand how engineers work in 3D CAD and simulation environments.
• Deliver high-fidelity clickable prototypes for stakeholder review.
• Present design rationale using tools such as FigJam, Miro, or PowerPoint.

Requirements

• Expert-level Figma proficiency, including component libraries, auto layout, variables, interactive prototyping, design tokens, and branching/versioning workflows.
• Figma design system management, including building and maintaining scalable design systems with variants, nested components, and token-based theming that maps cleanly to React component libraries.
• Figma-to-React pipeline experience, including hands-on use of code generation and handoff tooling such as Locofy, Anima, Builder.io, or Figma Dev Mode to produce production-quality React/TypeScript output. Ability to structure Figma files so generated code stays clean and maintainable.
• Figma AI features experience, such as AI-powered asset search, rename layers, visual suggestions, first drafts, plus third-party AI plugins to accelerate design workflows.
• Strong UI/UX fundamentals, including information architecture, interaction design, user flows, wireframing, usability testing, and accessibility (WCAG 2.1 AA).
• Front-end design literacy, including working knowledge of HTML, CSS, and React component architecture. Ability to inspect and red-line designs for developers. Familiarity with CSS-in-JS, Tailwind, or styled-components is a plus.
• Data-dense and technical UI experience designing complex interfaces such as dashboards, data tables, tree views, property panels, and multi-step workflows.
• Rapid business-requirements translation from engineers and product managers into clear interaction models and visual designs.
• Prototyping and stakeholder communication through high-fidelity clickable prototypes and clear rationale, using tools such as FigJam, Miro, or PowerPoint.

Technologies

• Figma, React, TypeScript
• Locofy, Anima, Builder.io, Figma Dev Mode
• FigJam, Miro, PowerPoint
• HTML, CSS, CSS-in-JS, Tailwind, styled-components
• Storybook, Tokens Studio, Style Dictionary, Chromatic, Zeplin
• WCAG 2.1 AA

Highly desirable skills

• Engineering/CAD/3D domain experience, including software used in engineering design, structural modeling, CAD/CAM/CAE, simulation, or technical/scientific applications.
• Marine or offshore engineering software familiarity, including shipbuilding, classification, or structural engineering workflows and terminology.
• Design system ↔ component library synchronization, such as keeping a Figma system in sync with a live React component library (for example via Storybook integration and token pipelines with Style Dictionary or Tokens Studio).
• Responsive and adaptive layout design, including experience across desktop, web, and potentially embedded/offline deployments.
• Motion and micro-interaction design to specify meaningful transitions and usability improvements in complex workflows.
• Modern design/dev collaboration tools such as Storybook, Chromatic, Zeplin, or similar.

Experience and fit

• 3+ years of professional UI/UX design experience, with at least 2 years focused primarily on Figma.
• Portfolio demonstrating complex, data-rich application design (not only websites or mobile consumer apps).
• Demonstrated experience delivering designs that were implemented in React-based front-end applications.
