Senior Java Developer



Overview:


We are seeking a skilled Senior Java Developer to join our team in developing a highly scalable library for method orchestration and execution in a distributed computing environment, leveraging AWS cloud infrastructure.


This role involves working with cutting-edge architecture, similar to a MapReduce framework, where tasks are distributed across multiple servers, coordinated to produce meaningful aggregated results.

  • Collaborate with the team to set up and configure AWS components (e.g., S3 for large payloads, Elasticsearch for consumer group monitoring).
  • Use DynamoDB as a secondary data store to ensure consistency and reliability of distributed tasks.
  • Work with the team to define workflows and ensure smooth communication between command producers and consumers.
  • Leverage Pub/Sub messaging systems to support asynchronous workflows and maintain high availability.


Required Skills:


  • Strong proficiency in Java Core (Java 18 or later) with experience in distributed computing.
  • Deep understanding of AWS services, including experience deploying Java applications within AWS environments.
  • Experience with Redis, including Redis Streams, Pub/Sub, and Reliable Queues.
  • Familiarity with DynamoDB for scalable and reliable data storage.
  • Knowledge of S3 for handling large data payloads in distributed architectures.
  • Understanding of Elasticsearch and event-driven systems in a cloud environment.
  • Ability to work in a highly distributed environment, with an emphasis on scalability and fault tolerance.


Preferred Qualifications:


  • Prior experience with distributed processing frameworks (e.g., MapReduce).
  • Experience with large-scale data processing in a multi-server environment.
  • Familiarity with event-driven architectures and microservices.
