  • Support production stability by troubleshooting incidents, identifying root causes, implementing fixes, and restoring service with urgency.
  • Perform code reviews, share technical guidance, and support engineering standards that improve code quality and delivery consistency across the team.
  • Collaborate with cross-functional teams in Agile delivery processes to refine requirements, estimate work, and deliver tested solutions within sprint timelines.
  • Contribute to application build-out, modernization, deployment, and maintenance activities across development and support lifecycles.

  • 6+ years of experience supporting mission-critical applications with a focus on resiliency, performance, security, and production issue resolution.
  • Experience using Git, Maven, Jenkins, Jira, or similar source control, build automation, continuous integration, and Agile delivery tools.
  • Experience with security implementation using JSON Web Tokens (JWT), OAuth, or similar authentication and authorization approaches.
  • Experience with Oracle, Cassandra, or similar relational database management system (RDBMS) or NoSQL platforms, including data modeling and Java persistence application programming interfaces (APIs) such as Hibernate, Spring Data, or EclipseLink.
  • Bachelor's degree in computer science, software engineering, or a related field, or equivalent combination of education, related experience and/or military experience.

Experience that would be great to have:
  • Experience with IBM Liberty, Spring Boot, Docker, or similar containerized application platforms.
  • Experience with test-driven development and test-first engineering practices.
  • Experience with C++ development and Virtual Memory System (VMS) platforms.
  • Experience working in Scrum or other Agile software delivery environments.
