What does a Java full stack developer with React do?

A Java Full Stack Developer with React is responsible for building both the backend and frontend of web applications. On the backend, they use Java technologies like Spring Boot to create APIs and manage data processing. On the frontend, they use React to develop interactive user interfaces. This role requires a solid understanding of databases, server-side logic, and client-side frameworks to deliver complete, functional web solutions.

What are the key skills and qualifications needed to thrive as a Java full stack developer with React?

To thrive as a Java Full Stack Developer with React, you need strong proficiency in Java for backend development, expertise in React.js for frontend, and a solid grasp of web technologies such as HTML, CSS, and JavaScript, often supported by a relevant degree or certifications. Familiarity with frameworks like Spring Boot, RESTful APIs, version control systems like Git, and databases such as MySQL or MongoDB is typically required. Excellent problem-solving, teamwork, and communication skills help you collaborate effectively and adapt to changing project demands. These skills and tools are crucial for building scalable, robust applications and ensuring seamless integration across the tech stack.

What are some common challenges Java full stack developers with React face when balancing front-end and back-end development tasks?

Java Full Stack Developers working with React often juggle the demands of both client-side and server-side development, which can present unique challenges. For example, integrating React-based front-end components with Java back-end APIs requires attention to data flow, state management, and consistency in API design. Additionally, keeping up with updates in both Java and React ecosystems, managing deployment pipelines, and ensuring seamless communication between front-end and back-end services are typical hurdles. Effective time management and clear communication with team members across specialties are key to overcoming these challenges.

Job description

Ridley is rebuilding the home transaction around the consumer.

Our mission is to eliminate the $100B homeowners lose every year to real estate commissions by replacing a fragmented, intermediary-driven process with AI. We believe software will become the primary interface for buying and selling a home, while human experts are brought in only where they create real value.

Backed by leading investors and with strong early traction, we're building the AI-native platform that will define the next generation of residential real estate.

The Role

We're looking for an exceptional Full Stack Engineer to help build the future of one of the world's largest industries.

You'll work directly with the CEO and founding team to design, build, and scale an AI-native product from the ground up. This isn't a role where you'll own a small corner of a mature codebase, you'll help define the architecture, product, and engineering culture of the company.

AI is central to how we build. We use the latest AI coding tools to move faster, automate repetitive work, and spend more time solving hard product and engineering problems.

What You'll Do
  • Own the design, architecture, and implementation of features across the stack—from frontend to backend to cloud infrastructure.
  • Build fast, intuitive user experiences with React, Next.js, and Tailwind.
  • Develop scalable backend services with Node.js and AWS.
  • Design and operate cloud infrastructure using AWS (CDK, CloudFront, API Gateway, DynamoDB, Lambda, SQS, SNS, Bedrock, S3, EC2, and Fargate).
  • Build AI-native product experiences by integrating frontier language models into core user workflows.
  • Design and implement agentic systems that leverage tool use, memory, retrieval, and orchestration to complete complex tasks on behalf of users.
  • Work AI-first, using tools like Claude Code, Cursor, Codex, and Copilot to dramatically accelerate development while maintaining a high quality bar.
  • Partner closely with product, design, and legal to ship secure, reliable, and scalable features.
  • Improve our engineering systems, CI/CD pipelines, and developer tooling as the company grows.
What We're Looking For
  • 3-5 years of experience building modern full stack applications, ideally at an early-stage startup.
  • Strong experience designing and operating production systems on AWS.
  • Deep expertise with React, Next.js, Node.js, and TypeScript.
  • Hands-on experience building AI-powered applications using modern foundation models (Anthropic, OpenAI, Bedrock, or similar).
  • Experience building agentic systems, including retrieval, tool calling, memory, evaluation, and multi-step orchestration.
  • Fluent with modern AI development tools such as Claude Code, Cursor, Codex, or Copilot—you use them to multiply your output, not just generate code.
  • Proven ability to design software architecture and make sound technical tradeoffs.
  • Strong product instincts and a track record of shipping polished, end-to-end features.
  • High ownership, excellent judgment, and the ability to move quickly through ambiguity.
Why Join Ridley

This is an opportunity to help redefine how millions of people buy and sell homes.

Ridley is already live with real customers, real revenue, and strong early momentum. We've been featured in The New York Times , The Daily , and CBS, and are backed by leading investors who believe, as we do, that AI will fundamentally reshape residential real estate.

If you want to help build the company that defines that future, we'd love to talk.
