  • Code documentation

  • Test reports

  • User manuals

Good documentation improves teamwork and future maintenance.

10. Product Maintenance and Updates

After product release:

  • Bugs are fixed

  • Firmware is updated

  • New features are added

This makes embedded engineering a long-term role, not just development work.

Types of Embedded Systems Engineering Roles
