About Revel

At Revel, we are revolutionizing the way the world's most critical hardware is controlled—across aerospace, automotive, energy, and manufacturing sectors. Our next-generation software stack combines an intuitive command/control interface, a specialized programming language tailored for hardware control, and a high-performance runtime environment. We empower engineers to build, test, and deploy critical systems rapidly, reliably, and safely.

Role Overview

Revel's product is used in control rooms, test facilities, and operational environments where the way information is presented directly affects safety and performance. As a Design Systems Engineer, you will own the research, standards, and design foundations that ensure our interfaces communicate clearly, accessibly, and unambiguously—even under stress, fatigue, and degraded conditions.

This role sits at the intersection of human factors engineering and design systems. You'll research and synthesize HMI standards and accessibility guidelines (ISA-101, NUREG-0700, WCAG, NASA-STD-3001, and others), then translate that research into the concrete design system—color palettes, semantic indicators, typography, iconography, layout patterns—that our product is built from. You'll define how Revel conveys meaning visually and ensure our interfaces hold up under the real-world conditions our customers operate in.

In the near term, that means auditing our existing interfaces against human factors best practices, standing up the foundational design system, and establishing the guidelines that new components and screens will be built from.

This is a high-leverage IC role. The system you build will shape every screen our customers use to control hardware that matters.

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.

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.

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.
