- Design, develop, and maintain scalable real-time and near-real-time data processing pipelines.
- Implement streaming data processing solutions using technologies such as Apache Kafka, Apache Flink, and Apache Spark.
- Develop and maintain Java-based services and integration components for processing data received from physical devices.
- Implement complex data transformations, mappings, validations, and enrichments to support business and technical requirements.
- Build and maintain event-driven integrations using Kafka, Kafka Streams, Kafka Connect, and messaging protocols such as AMQP.
- Ensure reliable data delivery to downstream consumers, applications, and storage systems.
- Implement and maintain MongoDB collections, data structures, and related application-level integrations, following architectural guidelines.
- Develop, deploy, and maintain cloud-native services primarily on AWS, leveraging Kubernetes and managed cloud services.
- Contribute to the modernization and migration of legacy data processing components toward Kafka-based streaming architectures.
- Collaborate with technical leads and engineering teams to translate architectural designs into robust, production-ready implementations.
- Troubleshoot performance, reliability, and data consistency issues across distributed data processing systems.
- Contribute to code quality, automated testing, CI/CD practices, and continuous improvement of engineering processes.
Required Skills and Experience:
- Strong professional experience in Data Engineering, with a focus on streaming data processing and distributed systems.
- Advanced programming skills in Java (11+), including experience with the Spring framework.
- Hands-on experience with Apache Kafka, including Kafka Streams, Kafka Connect, and the development of Kafka-based integrations.
- Practical experience with streaming and distributed processing frameworks such as Apache Flink, Apache Spark, or Spark Streaming.
- Solid understanding of event-driven architectures, asynchronous communication patterns, and messaging systems, including AMQP.
- Experience designing and implementing data transformation, enrichment, and integration pipelines.
- Experience developing and integrating microservices and distributed applications.
- Hands-on experience with AWS cloud services, particularly S3, SQS, and EKS.
- Experience deploying and operating containerized applications using Docker and Kubernetes.
- Working knowledge of MongoDB, including collections, document structures, and Java-based data access.
- Familiarity with Redis and its use in distributed applications.
- Experience with Git-based development workflows and CI/CD pipelines, preferably using GitLab and GitLab CI/CD.
- Strong troubleshooting and problem-solving skills, particularly in distributed, high-throughput data processing environments.
- Ability to work collaboratively with technical leads and cross-functional engineering teams, while taking ownership of implementation and delivery.
Nice to Have:
- Experience with Apache Pulsar or Apache Storm, particularly in legacy system maintenance or modernization initiatives.
- Familiarity with Microsoft Azure services and hybrid or multi-cloud environments.
- Experience processing telemetry, IoT, or other event data generated by physical devices.
- Knowledge of SMTP-based integrations.
- Experience migrating legacy messaging and stream processing solutions to modern Kafka-based architectures.
