Position Overview
A growing fintech organization is seeking a talented Java Developer with experience integrating Generative AI technologies into enterprise-grade systems. This role involves developing backend services, APIs, and data-driven applications that enhance financial operations through AI automation and intelligent insights. The ideal candidate combines strong Java engineering skills with curiosity and hands-on experience applying LLMs or other AI models in production environments.


Key Responsibilities

  • Design, develop, and maintain Java-based microservices and APIs to support AI-enhanced financial applications.

  • Collaborate with data science and AI engineering teams to integrate Generative AI models (e.g., OpenAI, Anthropic, Hugging Face) into backend systems.

  • Implement scalable and secure solutions for data ingestion, transformation, and model inference.

  • Build and maintain RESTful and event-driven architectures optimized for high performance and low latency.

  • Contribute to prompt optimization, model evaluation, and the fine-tuning of AI-driven application components.

  • Write clean, efficient, and maintainable code following best practices for software design and testing.

  • Participate in code reviews, architectural discussions, and Agile ceremonies.

  • Ensure high availability, reliability, and security of production systems.

  • Continuously evaluate new technologies to improve AI integration and developer efficiency.


Qualifications

  • Bachelor's degree in Computer Science, Engineering, or a related technical field.

  • 4-6+ years of professional software development experience with Java (Spring Boot, Quarkus, or Micronaut preferred).

  • Solid understanding of microservice architectures, REST APIs, and event-driven systems.

  • Hands-on experience working with or integrating Generative AI models via APIs or SDKs (e.g., OpenAI, Vertex AI, Bedrock).

  • Familiarity with AWS or other cloud platforms for deploying and managing AI applications.

  • Strong understanding of data pipelines, JSON, and message queues (Kafka, RabbitMQ, or SNS/SQS).

  • Experience with CI/CD pipelines, Git-based workflows, and DevOps best practices.

  • Excellent communication and collaboration skills across cross-functional technical teams.


Preferred Qualifications

  • Experience in financial technology or data-intensive environments.

  • Knowledge of Python for AI model experimentation or prompt engineering.

  • Familiarity with RAG (Retrieval-Augmented Generation) architectures and vector databases.

  • Exposure to containerization (Docker, Kubernetes) and infrastructure-as-code (Terraform, CloudFormation).

  • Interest in exploring multi-agent systems, AI-driven automation, or LLM application frameworks.
