Design Systems Engineer, HMI

Team: Product

Location: Los Angeles

Workplace Type: onsite

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.

Qualifications

• 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 Qualifications

• 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.
