  • Support appropriate certifications and compliance requirements, including PCI, GLBA, Safe Harbor, and others.
  • Drive performance engineering of the enterprise software architecture and provide guidance, advice, or training to other application developers.
  • Improve and expand the existing platform by ensuring it is resilient, secure, and scalable.
  • Use AI tools effectively as part of daily development work, including tools such as Claude Code, Copilot, or similar platforms.
Skills Required
