Job description

Overview:
Job Title: Full Stack Developer (Java Spring Boot & Angular)
Company: R2 Technologies
Location: Alpharetta, GA (Hybrid / Remote Options Available)
Employment Type: Full-Time / Contractual
About R2 Technologies: R2 Technologies is a Certified Minority Business Enterprise (MBE) headquartered in Alpharetta, GA. With over two decades of experience across global markets, we have built a reputation as a trusted partner for IT staffing excellence and cutting-edge digital product innovation. We are driven by innovation and operate on a simple philosophy: "We deliver what we promise, and we promise only what we can deliver." Beyond providing top-tier IT talent to industries ranging from Healthcare to Financial Services, R2 builds cutting-edge proprietary solutions like SmartEnt-an Enterprise AI & IoT Intelligence Platform utilizing advanced NLP and AI technologies. By partnering closely with our clients, we deliver technology-driven outcomes that are realistic, measurable, and impactful.
Job Summary: R2 Technologies is seeking a forward-thinking Full Stack Developer to build highly scalable, enterprise-grade applications. This is not a traditional full-stack role; we expect our engineers to operate at the cutting edge of productivity by utilizing AI-aided development tools (such as GitHub Copilot, Cursor, or Tabnine) to accelerate the software development lifecycle. You will be responsible for designing robust backend microservices with Java Spring Boot and creating responsive, intuitive user interfaces with modern Angular. Furthermore, you will play a crucial role in ensuring our architectures are "AI-ready," building systems that seamlessly connect with agentic AI platforms, workflow automation tools like n8n, and leading language models.
Key Responsibilities: * Architect, develop, and maintain robust backend microservices using Java and Spring Boot.
  • Build dynamic, responsive, and accessible single-page applications (SPAs) using modern Angular and TypeScript.
  • Actively utilize AI-assisted coding tools (e.g., GitHub Copilot, Cursor) to write boilerplate code, generate unit tests, and optimize complex logic, maximizing delivery speed and code quality.
  • Design APIs and data models that are future-proofed for AI integration, allowing seamless data flow into RAG (Retrieval-Augmented Generation) systems.
  • Integrate third-party AI APIs (including models like Grok, OpenAI, or Claude), cloud services, and IoT data streams into web applications.
  • Orchestrate intelligent, multi-step workflows using agentic AI frameworks like LangChain and automation platforms like n8n to reduce manual operational overhead.
  • Implement modern CI/CD pipelines and deploy containerized applications (Docker/Kubernetes) to cloud environments (AWS, Azure, or GCP).
  • Participate in code reviews, focusing not just on syntax, but on security, performance, and the effective use of AI-generated code.

Qualifications: * Up to 3 years of hands-on experience in full-stack software development.
  • Strong proficiency in Java (Java 17+) and the Spring Boot ecosystem.
  • Deep understanding of modern Angular, TypeScript, HTML5, and CSS3/SASS.
  • Proven experience or strong familiarity working alongside AI coding assistants to enhance productivity.
  • Familiarity with agentic workflows, LLM orchestration (e.g., LangChain), and visual automation tools like n8n is highly preferred.
  • Knowledge of relational databases (PostgreSQL, MySQL) and NoSQL databases (MongoDB, DynamoDB).
  • Experience with cloud platforms (AWS, Azure, or GCP) and modern DevOps practices.
  • Excellent communication skills and the ability to adapt quickly to new, future-proof technologies in a rapidly changing tech landscape.

Skills:
