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.
