Using index and match to look up employee ID, skill code and return relevant exp date

Hi everyone

I am attempting to create a skill matrix for a work group. I have a clean data source whereby I can match an employee ID and skill code to return the relevant expiry date. From there I will apply traffic light conditional formatting to highlight training that needs to be renewed.

I am having trouble creating an index / match formula that can handle my two criteria. I have attached a sample data set. Given the large number of employees, it is not practical to use helper columns.

Appreciate any help offered to solve!
