No H1B
U.S. Citizen Only
Responsibilities
Research and synthesize HMI design standards, human factors guidelines, and accessibility requirements relevant to Revel's target industries (aerospace, energy, nuclear, manufacturing)
Define and document Revel's design system: color usage philosophy, semantic indicator patterns, typography, iconography, spatial layout, and interaction conventions
Establish guidelines for how the product conveys state, alarms, warnings, faults, and nominal conditions
Audit existing product interfaces against human factors best practices and accessibility standards, and drive remediation of gaps
Design and specify component-level behavior: how individual UI elements communicate meaning across visual channels (color, shape, iconography, text, motion, position)
Develop guidelines for configurable elements (e.g., customer color conventions) that preserve safety semantics while accommodating industry-specific norms
Collaborate with product designers and frontend engineers to implement the design system and ensure fidelity from specification to shipped product
Qualification
Required
4+ years of experience in human factors engineering, HMI design, design systems, or a related discipline
Demonstrated ability to translate standards and research into actionable design specifications and component libraries
Familiarity with one or more HMI or accessibility standards such as ISA-101, NUREG-0700, WCAG 2.1, MIL-STD-1472, or NASA-STD-3001
Strong understanding of color perception, color vision deficiency, and multi-channel information encoding in interface design
Experience building or significantly contributing to a design system (tokens, components, patterns, documentation)
Proficiency with design tools (e.g., Figma) and the ability to specify components precisely enough for engineering implementation
Excellent written communication—you'll be writing guidelines, specifications, and rationale documents that the team builds from
Comfort working across disciplines: you'll partner with product designers, frontend engineers, and domain experts daily
Preferred
Background in aerospace, defense, nuclear, energy, or process control industries
Familiarity with high-performance HMI principles (Hollifield, ASM Consortium guidelines)
Experience with control room or operational environment design
Familiarity with frontend technologies (HTML/CSS/JS, React) or experience working within design-to-code workflows
Experience conducting or applying findings from usability studies in safety-critical contexts
Graduate degree in human factors, cognitive engineering, systems engineering, or a related field
