  • Build and manage Apache Kafka producers, consumers, and topic configurations to support real-time event streaming and data pipeline workflows.
  • Integrate Claude AI (Anthropic) APIs into backend services to enable intelligent automation, natural language processing, and AI-assisted decision-making features.
  • Write and optimize complex SQL queries, stored procedures, and schema designs across relational databases (PostgreSQL, MySQL, or Oracle).
  • Develop and expose RESTful APIs, ensuring proper documentation via Swagger/OpenAPI and adherence to security best practices.
  • Participate in CI/CD pipeline management using tools such as Jenkins, GitHub Actions, or Azure DevOps, and contribute to containerized deployments via Docker and Kubernetes.
  • Collaborate with product owners, QA, and DevOps teams in an Agile/Scrum environment to deliver iterative, well-tested software.
  • Conduct code reviews, mentor junior developers, and uphold engineering standards across the team.

REQUIRED QUALIFICATIONS

  • Demonstrated experience building and operating Apache Kafka-based event-driven architectures (producers, consumers, schema registry, partitioning strategies).
  • Practical experience integrating or working with large language model (LLM) APIs or generative AI tools (Claude, GPT, Gemini, or equivalent) in production backend systems.
  • Strong SQL skills including schema design, query optimization, and stored procedure development across one or more relational databases.
  • Proficiency with RESTful API design, JSON data modeling, and microservices communication patterns.
  • Bachelor's degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).

  • Exposure to prompt engineering, LLM API orchestration frameworks (LangChain4j, Semantic Kernel for Java, or similar), or AI-assisted developer tooling.
  • Knowledge of observability and monitoring tools such as Datadog, Dynatrace, or AppDynamics.
  • Prior experience in Agile/Kanban delivery with distributed or hybrid teams.
