Front-End UI Developer

Peraton is seeking a Front-End UI Developer
. This is a hands-on development role serving as the technical bridge between UX Design and Development, transforming approved Figma designs and prototypes into polished, accessible, responsive, and functional user interfaces.

The role combines front-end development, UX/UI design skills, Figma proficiency, AI-assisted development, rapid prototyping, and emerging technology to ensure design intent is maintained through implementation.

The Front-End UI Developer is expected to operate within the UX team’s Raising the Bar standards, bringing commercial-grade quality, craftsmanship, communication, velocity, and attention to detail to every deliverable.

Hands-On UI Development

• Directly develop and implement production-quality front-end interfaces
  , not simply provide recommendations or development guidance.
• Translate high-fidelity Figma designs and interactive prototypes into functional UI code
  .
• Build responsive interfaces using HTML5, CSS, JavaScript/Type Script, React, Angular, or applicable modern frameworks
  .
• Support UI development across responsive web, native mobile/iOS, SharePoint, Sitecore, and enterprise platforms
  .
• Develop reusable UI components, interaction patterns, design tokens, and front-end design-system elements.
• Partner with backend engineering to integrate polished presentation layers with APIs, services, data, and enterprise systems.
• Conduct implementation reviews and directly correct UI inconsistencies when appropriate.

UX-to-Development Liaison

• Serve as the primary technical bridge between UX and development
  , protecting design intent throughout implementation.
• Work directly within Figma alongside UX designers to understand interaction behavior, responsive rules, component states, accessibility requirements, and design rationale.
• Identify technical considerations early enough to influence designs before development handoff.
• Ensure production interfaces accurately reflect approved designs across layout, typography, spacing, hierarchy, interaction, responsiveness, animation, and component behavior
  .
• Help eliminate the traditional gap between a polished UX prototype and the final developed product.

AI-Enabled Development

• Actively incorporate AI-assisted development tools into daily workflows to increase speed, quality, and delivery capacity.
• Use AI to accelerate code generation, refactoring, debugging, prototyping, documentation, accessibility evaluation, test creation, design-to-code workflows, and technical exploration
  .
• Use AI to rapidly transform concepts and Figma designs into functional prototypes and proofs of concept.
• Evaluate AI-generated code and output through human technical judgment, security requirements, accessibility standards, performance, and maintainability.
• Continuously evaluate emerging AI capabilities that can improve the UX-to-development workflow.

AI is expected to increase capability and velocity—not replace engineering judgment.

Rapid Prototyping & Emerging Technology

• Build functional prototypes supporting Phase Zero, Art of the Possible, usability testing, and stakeholder demonstrations
  .
• Rapidly explore new interaction models before significant development investment.
• Support experiences across native mobile/iOS, wearables, VR/XR, mixed reality, spatial computing, immersive technology, and emerging platforms
  .
• Collaborate with UX Architects and Designers to determine when emerging technology provides meaningful user or mission value.

Quality & Craft

• Deliver interfaces that meet the UX team’s commercial-grade quality standard
  .
• Maintain pixel-level attention to spacing, alignment, typography, responsive behavior, component consistency, states, motion, and interaction details
  .
• Benchmark implementation quality against leading…
