• Design and build modern, scalable solutions using Java and AWS technologies
• Create and maintain documentation including solution diagrams, trade flows, and current vs. target state overviews
• Collaborate with traders and stakeholders to iterate quickly and incorporate feedback into solutions
• Participate in Agile ceremonies, unit testing (participate in planning and execution of test suites), and deployment using CI/CD pipelines
• Partner with others in the organization to advance the client's overall IT capabilities in the areas of real-time messaging, application integration, application high-availability, other
