UX/UI Developer

This role is for someone who can bridge the gap between complex user flows and high-performance micro-frontend (MFE) architectures. If you take initiative, thrive in shifting environments, and want to own the front-end lifecycle from prototype to deployment, you’ve found your team.

The Mission (Core Responsibilities)

• Design & Prototyping: Collaborate with stakeholders to create user flows, wireframes, and high-fidelity interactive prototypes. You must be comfortable mocking up wireframes in Figma or directly within React to ensure rapid iteration.

• React Implementation: Develop reusable, modern UI components and front-end libraries using React.js to build scalable, high-performance web applications.

• Responsive Design: Ensure every application is optimized for a seamless, accessible experience across mobile, tablet, and desktop devices.

• State & Data Management: Oversee complex data flow and storage using modern state management libraries such as Redux or the Context API.

• Performance & Testing: Monitor front-end performance, debug intricate issues, and maintain rigorous unit and integration tests using tools like Jest and React Testing Library.

Technical Expertise

• React Proficiency: Expert-level knowledge of JSX, hooks, Virtual DOM, and component lifecycles.

• Core Web Stack: Advanced proficiency in HTML5, CSS3 (Flexbox, Grid), and Modern JavaScript (ES6+).

• UI/UX Design Fundamentals: A solid understanding of user-centered design principles, typography, and color theory.

• Micro-Frontend (MFE) Architecture: Experience designing and maintaining multiple micro-frontend services using single-spa.

• Cross-Application Communication: Ability to implement robust communication patterns between MFEs using utility modules, shared state, or custom browser events for a unified user experience.

• Independent Deployment: Mastery of independent CI/CD pipelines, allowing individual features (e.g., checkout, profile, search) to be deployed without redeploying the entire platform.

• Shared Design Systems: Lead the development of a global theme to maintain visual consistency across all decoupled MFEs.

• System Optimization: Expertise in lazy loading, import maps for version control, and managing shared dependencies to prevent duplicate library downloads.

The Bonus Stack (Preferred Backend & Cloud)

• Node.js Development: Experience building scalable server-side applications and RESTful/GraphQL APIs using Node.js and Express.

• AWS Infrastructure: Familiarity with AWS services such as S3 and CloudFront (for MFE hosting), Lambda (serverless functions), and API Gateway.

• DevOps & CI/CD: Experience configuring automated pipelines (e.g., AWS CodePipeline, GitHub Actions) to sync MFEs with S3 buckets and manage CloudFront invalidations.

• Database Knowledge: Basic understanding of NoSQL (DynamoDB) or SQL (Postgres) for data persistence.

Personality & Traits

• Self-Starter: You take the initiative to identify site improvements, manage ticketing workflows, and independently develop high-quality solutions.

• Adaptable Team Player: You expertly manage competing priorities across multiple teams, pivoting seamlessly to meet shifting project demands.

• Technical Problem Solver: You have a track record of streamlining fragmented architectures by consolidating redundant methods (MUI, Bootstrap, Styled Components) into unified, reusable shared components.

Clearance & Eligibility

• Must be a US Citizen.

• Must have the ability to obtain a US Government Public Trust clearance. (Preference given to candidates with active or recent ICE or CBP clearance).
