About the Role

We build and operate a modern, cloud-based, AI-enabled analytics platform for Commercial Real Estate (CRE) organizations. The platform delivers scalable, secure, and high-performance analytics that transform complex operational data into actionable insights.

As a React & Java Developer, you will be a full-stack engineer responsible for building end-to-end features across both frontend and backend systems. You will develop polished, accessible, and performant user interfaces using React and TypeScript, while also designing and implementing robust, scalable backend services using Java and Spring Boot, integrated with GraphQL APIs, NestJS-based microservices, and enterprise data systems. This role emphasizes full-stack craftsmanship, engineering quality, and AI-augmented development as a core expectation.

Responsibilities

Full-Stack Development

• Design, develop, and independently deliver moderately complex features spanning frontend and backend with limited guidance.

• Build React/TypeScript-based user interfaces that are scalable, accessible, and performant.

• Develop Java/Spring Boot microservices that handle business logic, data processing, and API integrations.

• Implement GraphQL APIs and integrate with NestJS-based microservices to deliver cohesive product features.

• Apply sound engineering judgment across the full technology stack, adhering to established architecture and coding standards.

• Demonstrate ownership of feature quality, maintainability, performance, and user experience outcomes.

Frontend Development

• Build scalable, reusable UI components aligned with design systems and shared component libraries using React and TypeScript.

• Implement state management and data fetching using GraphQL (Apollo Client).

• Ensure high standards of performance, responsiveness, accessibility (WCAG), and cross-browser compatibility.

• Collaborate closely with UX designers to translate Figma designs, wireframes, and prototypes into production-ready interfaces with pixel-accurate layouts.

• Provide input on usability and UX improvements based on frontend implementation experience.

Backend Development

• Design and implement RESTful APIs and GraphQL APIs using Java and Spring Boot.

• Build and maintain microservices architecture with proper separation of concerns, modularity, and scalability.

• Implement data persistence layers using JPA/Hibernate with relational databases (PostgreSQL, MySQL, SQL Server).

• Integrate with enterprise data systems, external APIs, and cloud services (Azure, AWS).

• Ensure API security using OAuth2, JWT, and Spring Security.

• Optimize backend performance through efficient database queries, caching strategies (Redis), and asynchronous processing.

• Implement event-driven architectures using message brokers (Kafka, RabbitMQ) where applicable.

Quality & Engineering Practices

• Write unit, integration, and end-to-end tests using:Frontend: Jest, React Testing Library, Mock Service Worker (MSW)Backend: JUnit, Mockito, Spring Boot Test, TestContainers

• Participate in code reviews with attention to code quality, performance, security, accessibility, and maintainability.

• Maintain and improve build tooling:Frontend: Webpack, ESLint, PrettierBackend: Maven/Gradle, SonarQube, Checkstyle

• Follow CI/CD practices and contribute to build and deployment pipeline maintenance.

• Support automated quality checks and continuously improve engineering standards and workflows.

• Monitor application performance and troubleshoot production issues across the full stack.

AI Augmentation & Agent Development

• Use AI-powered development tools such as Cursor AI and GitHub Copilot across the SDLC to improve productivity in coding, testing, refactoring, and documentation.

• Build or contribute to basic AI agents and AI-augmented automation for development workflows, including:Test generation and maintenance (frontend and backend)Code scaffolding and refactoringAPI documentation generationAccessibility auditing and validationCode quality and security scanning

• Actively explore and adopt emerging AI tools and practices that enhance engineering velocity and code quality.

• Contribute ideas and improvements to developer productivity, tooling, and automation initiatives.

Collaboration & Growth

• Collaborate with frontend engineers, backend engineers, product managers, and designers in an Agile environment.

• Participate in sprint planning, design reviews, technical discussions, and retrospectives.

• Share knowledge through documentation, technical discussions, and mentoring junior engineers.

• Stay current with:Frontend: React ecosystem, GraphQL best practices, modern CSS, and frontend toolingBackend: Java ecosystem, Spring framework, microservices patterns, and cloud-native architectures
