• Drive technical vision and strategy for our core platforms, ensuring alignment with business objectives and long-term technology roadmap.
• Conduct architectural reviews, identify technical debt, and propose solutions for continuous improvement.
• Stay abreast of emerging technologies and industry trends, evaluating their applicability and recommending adoption where appropriate.

Design & Development:

• Design and implement robust, high-throughput Kafka topics, consumers, producers, and streams (Kafka Streams/KSQL).
• Architect and design Java-based microservices that effectively integrate with Kafka for event communication and data synchronization.
• Lead the selection and integration of appropriate technologies and frameworks for event processing, data serialization, and API development.
• Develop proof-of-concepts (POCs) and prototypes to validate architectural choices and demonstrate technical feasibility.
• Contribute hands-on to critical path development when necessary, demonstrating coding excellence and leading by example.

Kafka Ecosystem Expertise:

• Deep understanding of Kafka internals, distributed systems concepts, and high-availability configurations.
• Experience with Kafka Connect for data integration, Schema Registry for data governance, and KSQL/Kafka Streams for real-time stream processing.
• Proficiency in monitoring, optimizing, and troubleshooting Kafka clusters and related applications.
• Knowledge of Kafka security best practices (authentication, authorization, encryption).

Technical Governance & Mentorship:

• Establish and enforce architectural governance, ensuring adherence to design principles and coding standards.
• Mentor and guide engineering teams on best practices for event-driven architecture, Kafka usage, and Java development.
• Foster a culture of technical excellence, collaboration, and continuous learning within the engineering organization.
• Communicate complex technical concepts effectively to both technical and non-technical stakeholders.

Performance, Scalability & Reliability:

• Design for high availability, fault tolerance, and disaster recovery.

• Define and implement strategies for performance optimization, monitoring, and alerting across the event-driven ecosystem.
• Ensure solutions are scalable to handle significant data volumes and transaction rates.

• Familiarity with Kafka Connect, Schema Registry, and Avro/Protobuf.
• Understanding of Kafka cluster operations, tuning, and monitoring.

• Strong understanding and practical experience with Event-Driven Architecture (EDA) principles and patterns:

  Event Sourcing, CQRS, Saga, Choreography vs. Orchestration.

• Extensive experience with Microservices architecture

  principles and patterns.
• Proficiency in designing RESTful APIs and asynchronous communication mechanisms.
• Experience with relational and NoSQL databases (e.g., PostgreSQL, MongoDB, Cassandra).
• Solid understanding of cloud platforms (AWS, Azure, GCP) and containerization technologies (Docker, Kubernetes).
