This is a 100% remote full-time opportunity.

Key Responsibilities

• Design, build, and operationalize messaging solutions using Amazon MQ (ActiveMQ/RabbitMQ) to support reliable communication between enterprise applications and services.
• Develop and maintain PHP-based integrations leveraging the STOMP protocol for message publishing, consumption, routing, and processing.
• Configure and manage Amazon MQ brokers across development, test, and production environments, ensuring high availability, scalability, and operational stability.
• Monitor messaging infrastructure and proactively troubleshoot broker performance issues, message delivery failures, queue backlogs, dead-letter queues, and connectivity problems.
• Collaborate with application development, infrastructure, security, and platform teams to onboard new messaging workloads and establish integration standards.
• Support the full lifecycle of messaging solutions, including architecture, implementation, testing, deployment, migration, and production support.
• Implement automation, observability, and CI/CD integration for messaging platforms, including monitoring, alerting, logging, and infrastructure provisioning.

Required Experience & Skills

• Strong hands-on experience with Amazon MQ and proven experience implementing STOMP-based messaging solutions in PHP applications
• Experience designing and supporting message-oriented middleware in enterprise environments.

• Experience troubleshooting broker performance issues, message delivery failures, and high-volume messaging workloads.
• Familiarity with AWS services and cloud-native integration patterns.
• Experience implementing monitoring, observability, and operational support processes for messaging platforms.

Nice-to-Have Skills (Differentiators)

• Experience with ActiveMQ Artemis, RabbitMQ, Apache Kafka, or other streaming/event platforms.
