UX/UI Developer

Mobomo•Washington, DC

About The Position

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.

Requirements

Expert-level knowledge of JSX, hooks, Virtual DOM, and component lifecycles.
Advanced proficiency in HTML5, CSS3 (Flexbox, Grid), and Modern JavaScript (ES6+).
A solid understanding of user-centered design principles, typography, and color theory.
Experience designing and maintaining multiple micro-frontend services using single-spa.
Ability to implement robust communication patterns between MFEs using utility modules, shared state, or custom browser events for a unified user experience.
Mastery of independent CI/CD pipelines, allowing individual features (e.g., checkout, profile, search) to be deployed without redeploying the entire platform.
Expertise in lazy loading, import maps for version control, and managing shared dependencies to prevent duplicate library downloads.
Must be a US Citizen.
Must have the ability to obtain a US Government Public Trust clearance.

Nice To Haves

Comfortable mocking up wireframes in Figma or directly within React to ensure rapid iteration.
Experience building scalable server-side applications and RESTful/GraphQL APIs using Node.js and Express.
Familiarity with AWS services such as S3 and CloudFront (for MFE hosting), Lambda (serverless functions), and API Gateway.
Experience configuring automated pipelines (e.g., AWS CodePipeline, GitHub Actions) to sync MFEs with S3 buckets and manage CloudFront invalidations.
Basic understanding of NoSQL (DynamoDB) or SQL (Postgres) for data persistence.
Preference given to candidates with active or recent ICE or CBP clearance.

Responsibilities

Collaborate with stakeholders to create user flows, wireframes, and high-fidelity interactive prototypes.
Develop reusable, modern UI components and front-end libraries using React.js to build scalable, high-performance web applications.
Ensure every application is optimized for a seamless, accessible experience across mobile, tablet, and desktop devices.
Oversee complex data flow and storage using modern state management libraries such as Redux or the Context API.
Monitor front-end performance, debug intricate issues, and maintain rigorous unit and integration tests using tools like Jest and React Testing Library.
Lead the development of a global theme to maintain visual consistency across all decoupled MFEs.
Take the initiative to identify site improvements, manage ticketing workflows, and independently develop high-quality solutions.
Expertly manage competing priorities across multiple teams, pivoting seamlessly to meet shifting project demands.
Streamline fragmented architectures by consolidating redundant methods (MUI, Bootstrap, Styled Components) into unified, reusable shared components.
