About the Role

NTT DATA is seeking a Full Stack Java Engineer with deep expertise in Apache Kafka and AWS Managed Streaming for Apache Kafka (MSK) to help lead the migration of enterprise Kafka infrastructure from self-managed environments to AWS MSK.

In this role, you'll design and build event-driven applications, modernize streaming platforms, and ensure a seamless, low-risk migration with minimal impact to business-critical systems.

Responsibilities
  • Lead the migration of on-premises or self-managed Kafka clusters to AWS MSK, including planning, sizing, replication, and production cutovers.
  • Design, develop, and maintain Java/Spring Boot microservices and REST APIs that publish and consume Kafka events.
  • Build and enhance full-stack applications using modern frontend technologies (React or Angular) where required.
  • Refactor Kafka producers and consumers to support AWS MSK, including IAM authentication, TLS, networking, and security best practices.
  • Optimize Kafka performance through effective partitioning, replication, retention, and consumer group management.
  • Implement monitoring and observability using CloudWatch, Prometheus, Grafana, or similar tools.
  • Develop migration strategies including validation, dual-read/dual-write, rollback planning, and production readiness.
  • Partner with DevOps teams to provision infrastructure using Terraform or CloudFormation.
  • Ensure secure, compliant implementations with encryption, IAM, mTLS, and SASL/SCRAM authentication.
  • Troubleshoot application, streaming, and infrastructure performance issues.
  • Produce technical documentation, migration runbooks, and operational procedures.
  • Mentor junior engineers and promote Kafka and AWS best practices.
Required Qualifications
  • 5+ years of software engineering experience with Java-based enterprise applications.
  • Strong expertise in Java (8/11/17), Spring Boot, and RESTful API development.
  • Deep experience with Apache Kafka, including:
  • Producers and consumers
  • Kafka Streams
  • Kafka Connect
  • Schema Registry (Avro or Protobuf)
  • Consumer groups and partitioning strategies
  • Proven experience implementing or migrating workloads to AWS MSK (including MSK Connect or MSK Serverless).
  • Hands‑on experience with AWS services including IAM, VPC, CloudWatch, Lambda, S3, and Secrets Manager.
  • Experience building full-stack applications using React or Angular.
  • Experience with CI/CD pipelines (Jenkins or GitLab CI), Infrastructure as Code (Terraform or CloudFormation), and container technologies such as Docker and Kubernetes.
  • Experience working with SQL and NoSQL databases including PostgreSQL, DynamoDB, or MongoDB.
  • Strong understanding of distributed systems, event‑driven architectures, scalability, and fault tolerance.
  • Experience supporting large‑scale production migrations with minimal downtime.
  • Excellent communication skills and the ability to collaborate across engineering and infrastructure teams.
  • Strong analytical and problem‑solving skills with the ability to work independently in fast‑paced environments.
Preferred Qualifications
  • Experience migrating from self-managed or Confluent Kafka environments to AWS MSK.
  • Financial services or other highly regulated industry experience.
  • AWS certifications (Solutions Architect, Developer Associate, or similar).
  • Experience implementing Kafka security using IAM, mTLS, SASL/SCRAM, and encryption best practices.
