How Do You Standardize Salary and Designation Based on Experience in a Startup?

Hello team members, I am working with a product-based IT startup. We have developers and testers, and I need to standardize the salary benchmarking along with designation and experience. Could anyone please help me out with the salary grid or salary benchmarking, which can be based on experience and offer salary and designation to a new employee or existing employee?

In our product-based IT startup, we have developers and testers, and I need assistance in standardizing the salary benchmarking, considering designation and experience. If anyone can provide guidance on creating a salary grid or benchmarking system that takes into account experience and offers appropriate salaries and designations for both new and existing employees, I would greatly appreciate it.

Thank you!
