What is a sustaining software engineer?

Sustaining Software Engineers are professionals responsible for maintaining, supporting, and improving existing software products after their initial release. They focus on fixing bugs, addressing customer-reported issues, ensuring compatibility with new technologies, and implementing minor enhancements to keep the software reliable and up-to-date. Unlike development engineers, who work primarily on new features or products, sustaining engineers ensure the ongoing stability and quality of released software. Their work is crucial for customer satisfaction and long-term software success.
