What you will do:

Develop, enhance, test, and support full-stack Java applications, services, and APIs, with ongoing ownership from implementation through production support.
Develop and support native iOS applications.
Support production and test environments by troubleshooting and debugging application issues, investigating incidents, restoring service, performing root-cause analysis, and remediating vulnerabilities.
Collaborate with Software Engineers, Business Systems Analysts, and other partners to deliver quality solutions and maintain stable application environments.
Contribute to monitoring, change management, system upgrades, disaster recovery, and continuous-improvement initiatives.

What you need to succeed:

At least 10 years of experience developing and supporting back-end Java applications in an enterprise environment, with strong knowledge of core Java/J2EE, the Spring Framework, Spring Boot, and Spring MVC.
