Join a dynamic platform engineering team supporting a large-scale migration of enterprise middleware services from on-premises environments to AWS. This role is ideal for a hands-on engineer who enjoys building secure, standardized, and highly automated middleware platforms across Linux, virtual machines, bare metal, containers, and cloud infrastructure.

Responsibilities

• Design and support standardized middleware platforms across Linux, VM, bare-metal, and container environments.
• Own key parts of the platform lifecycle, including packaging, deployment, upgrades, patching, and day-to-day operational support.
• Create clear separation between middleware platform engineering and application-level configuration.
• Build and maintain equivalent infrastructure on AWS EC2 as workloads transition from on-premises environments.
• Develop reusable automation for provisioning and configuration using Terraform and Ansible.
• Establish platform standards, deployment patterns, operational guardrails, and support controls.
• Support the transition from Oracle Java to OpenJDK.
• Evaluate product features and configuration choices with security, resiliency, performance, and supportability in mind.
• Collaborate in a hybrid work environment and participate in onsite requirements as needed.

Skills

• Strong background in enterprise Java middleware platform engineering.
• Hands-on experience with several middleware technologies such as WebSphere, WebSphere Liberty, Tomcat, JBoss, WebLogic, Apache HTTP Server, or IBM HTTP Server.
• Solid Linux administration skills.
• Practical experience using Ansible for middleware installation, configuration, patching, and automation.
• Practical experience using Terraform for repeatable infrastructure provisioning, especially in AWS.
• Experience operating middleware on AWS EC2 without relying on managed middleware services.
• Understanding of Java runtime standards, including Oracle Java and OpenJDK.
• Ability to work hands-on while also providing architectural guidance and technical leadership.

Preferred Skills

• Experience engineering middleware in virtualized, bare-metal, and container-based environments.
• Exposure to large-scale cloud migration initiatives.
• Ability to assess platform design decisions through the lens of security and operational reliability.
• Strong problem-solving skills and a proactive approach to platform support.
• Clear communication and collaboration skills in cross-functional environments.
