Berkeley Heights, NJ and San Francisco , CA (respectively) Contract - W2

Job Description:

We are seeking an Android, UI Components for Android POS, Web & Mobile Frameworks Resource having 8+ years of professional experience to develops and maintains reusable UI libraries, SDKs, and design systems using Kotlin and Jetpack Compose. They ensure pixel-perfect design implementation, high performance, and accessibility, while optimizing UI stability for Android applications. This role frequently bridges design and engineering teams, creating scalable UI frameworks. This role requires close collaboration with cross‑functional teams, adherence to DevOps and Agile practices, and ownership of service quality and delivery.

Key Responsibilities Component Development:

Build and maintain reusable UI components, modules, and libraries using Jetpack Compose and Kotlin.

Design System Implementation:

Implement design tokens, theming, and styling, ensuring consistency across applications.

Design System Development:

Build and maintain a library of reusable UI components (e.g., buttons, cards, navigation stacks) that serve as the "source of truth" for the app''s look and feel

Design Token Integration:

Implement "design tokens"-centralized variables for colors, typography, and spacing-to ensure visual consistency across the platform.

Figma Translation:

Collaborate closely with designers to translate high-fidelity designs and prototypes into production-ready code.

API Design:

Create scalable, consumer-friendly APIs for UI components that are easy for other engineers to integrate while hiding complex internal logic.

Performance Optimization:

Profile and optimize UI rendering, focusing on minimizing lag, managing memory usage, and ensuring efficient recomposition in Jetpack Compose.

Performance Optimization:

Optimize UI for performance, focusing on Compose recomposition, memory management, and smooth rendering.

Accessibility & Quality:

Ensure UI compliance with accessibility standards (A11y) and write UI tests (Espresso) to prevent regressions.

Accessibility & Internationalization:

Ensure every component meets accessibility standards (like WCAG) and supports various screen sizes, orientations, and right-to-left (RTL) languages

Documentation:

Create clear documentation, usage examples, and API guides for developers consuming the components.

Collaboration:

Work with designers and product teams to translate mockups into pixel-perfect code.

Mandatory Technical Skills & Competencies Languages:

Strong proficiency in Kotlin.

UI Frameworks:

Deep expertise in Jetpack Compose (state hoisting, modifiers, custom layouts, slot APIs) and traditional XML Views.

Architecture:

Experience with modern Android architectural patterns.

Tools:

Proficient with Android Studio, Gradle, and version control (Git). Developer Experience (DevEx): A passion for helping other engineers work faster by providing clear documentation, "playground" apps, and migration guides.

Framework Knowledge:

Familiarity with Android internals (e.g., custom views, graphics rendering) and modern architecture patterns like

MVI or MVVM System Knowledge:

Understanding of Android design guidelines, Material Design, and accessibility best practices Understanding of distributed tracing and logging. Cloud concepts like fundamentals, App Configuration / App Settings, Key Vault, Cache, Service Bus (queues/topics), Event driven architecture, Blob Storage, cloud security, scalability, and resiliency patterns Understanding of Microservice Development design, implementation, Middleware (Kafka), filters, exception handling, and logging, Authentication and authorization (JWT/OAuth concepts), Performance optimization and secure coding practices

Agile and Collaboration Tools:

Sprint planning, work item tracking, and agile delivery, Technical documentation and knowledge sharing Soft Skills Strong problem-solving and analytical skills Clear communication with technical and non‑technical stakeholders Ownership mindset and production‑grade engineering discipline Ability to work independently and within cross‑functional teams
