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. You'll work closely with engineering, DevOps, and infrastructure teams to deliver highly scalable, secure, and resilient solutions. 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. ## Related Videos - [From event streaming to event sourcing 101](https://www.wearedevelopers.com/videos/91-from-event-streaming-to-event-sourcing-101) - [Kafka Streams Microservices](https://www.wearedevelopers.com/videos/168-kafka-streams-microservices) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) - [NoSQL Data Modeling for Front-end Developers](https://www.wearedevelopers.com/videos/297-nosql-data-modeling-for-front-end-developers) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
