• Implement secure data ingestion, text chunking, embedding generation, and data synchronization workflows
• Monitor, benchmark, and evaluate non-deterministic AI outputs, token usage, latency, and prompt accuracy
• Develop secure, well-documented RESTful APIs and event-driven data flows using Kafka/RabbitMQ
• Containerize applications using Docker and manage deployments on cloud platforms (AWS/Azure/Google Cloud Platform)
• Write clean, maintainable code backed by comprehensive unit, integration, and evaluation tests

Requirements:

• Bachelor's or Master's degree in Computer Science, Software Engineering, Information Technology, or a closely related technical field
• 4+ years of professional backend development experience utilizing Java (JDK 17+), Spring Boot, Hibernate/JPA, and microservices architecture
• Hands-on experience integrating LLMs (OpenAI, Anthropic, open-source models) into enterprise applications
• Familiarity with Java-specific AI ecosystems such as Spring AI or LangChain4j
• Understanding of vector databases, embeddings, semantic search, and context window optimization
• Strong proficiency with relational databases (PostgreSQL, MySQL, SQL Server) and familiarity with NoSQL or vector storage systems
• Experience with containerization (Docker, Kubernetes) and CI/CD pipelines deployed on major cloud infrastructure
• Mastery of object-oriented design patterns, asynchronous programming, and API security (OAuth2/JWT)

Desired skills:

• Prior experience with financial systems, client onboarding platforms, or enterprise master/reference data solutions
• Experience in Agile product delivery, roadmap planning, and backlog prioritization
• Knowledge of cloud-native architectures and modern DevOps practices
• Familiarity with regulatory, risk, and governance considerations within large financial institutions
