In this role, you will contribute to the migration of an existing on-premises application to AWS cloud infrastructure, ensuring reliability, data integrity, and minimal operational disruption during the transition. As the system is modernized, you will help evolve the architecture toward a modern, service-oriented platform that supports large-scale operational workflows and distributed systems. This role requires strong hands-on engineering skills and experience working with both legacy systems and modern cloud-native technologies. What you will be doing: Platform Modernization & Cloud Migration + Contribute to the design and execution of the migration of an on-premises system to AWS cloud infrastructure. + Modernize and refactor a legacy PHP-based application to support scalable and reliable cloud deployment. + Improve system architecture, modularity, and maintainability while preserving compatibility with existing integrations. + Optimize database design and data access patterns for performance and scalability. + Modernize background processing, scheduled jobs, and batch workloads using cloud-native services. + Ensure system reliability, service continuity, and data integrity throughout the migration process. + Develop comprehensive testing, validation, and rollback strategies for production deployments. + Create operational documentation, migration procedures, and system runbooks Platform Development & Evolution + Design and build scalable services and APIs that extend the platform's capabilities. + Develop systems that ingest and process operational data and system telemetry. + Implement event-driven workflows and automation that improve operational efficiency. + Improve system observability, monitoring, and operational reliability. + Collaborate with cross-functional teams to design and deliver platform capabilities aligned with long-term architecture goals. ## Related Videos - [Crypto-secure Data Management with In-Database Blockchain](https://www.wearedevelopers.com/videos/632-crypto-secure-data-management-with-in-database-blockchain) - [Getting to Know Your Legacy (System) with AI-Driven Software Archeology](https://www.wearedevelopers.com/videos/1437-getting-to-know-your-legacy-system-with-ai-driven-software-archeology) - [Crew Management System for Airlines: Plan duties for pilots & flight attendants worldwide](https://www.wearedevelopers.com/videos/1444-crew-management-system-for-airlines-plan-duties-for-pilots-flight-attendants-worldwide) - [Build Delightful Mobile Experiences with Kotlin, Realm, and Atlas Device Sync](https://www.wearedevelopers.com/videos/694-build-delightful-mobile-experiences-with-kotlin-realm-and-atlas-device-sync) - [Why your codebase lies to AI?](https://www.wearedevelopers.com/videos/100281-why-your-codebase-lies-to-ai) - [Grappling With Clunky Old Software?
