About the role

Software Engineer to own and evolve internally developed business applications, including AI-assisted or rapid-developed code, transitioning them into long-term IT support with maintainability, security, and reliable deployment practices.

Responsibilities

  • Take technical ownership of internally developed applications as they transition from their original creators to IT.
  • Learn and document existing application architecture, code, integrations, dependencies, data flows, and deployment processes.
  • Maintain, troubleshoot, and enhance existing applications based on business requirements.
  • Review AI-generated and rapidly developed code for reliability, security, maintainability, and technical debt.
  • Refactor or redesign components where necessary to establish a sustainable production application.
  • Develop new application functionality, APIs, integrations, and automation.
  • Establish appropriate source control, branching, code review, testing, and release practices.
  • Implement and maintain CI/CD pipelines and repeatable deployment processes.
  • Partner with Infrastructure, DevOps, Security, and business stakeholders to ensure applications meet enterprise operational and security requirements.
  • Implement appropriate authentication, authorization, logging, monitoring, secrets management, backup, and recovery capabilities.
  • Troubleshoot production issues and perform root-cause analysis.
  • Develop technical documentation and operational runbooks so applications can be supported by the broader IT organization.
  • Evaluate AI-assisted development tools and techniques where they can improve development velocity without sacrificing maintainability or security.
  • Help establish standards for transitioning future internally or AI-developed applications into production IT ownership.
