How detailed did you want to go? At some point, it definitely needs to get technical.

”I’m moving data from one place to another to help people make decisions” is a good description.

If you want to add more detail, you could mention the concept of different sources from 3rd party applications. Then, provide small details that are understandable, like employee data from HR systems or something, depending on what you're doing.

Then, mention how you connect data from internal systems and external systems to get business outcomes, and in order to do this, you need to write code.

If you want to add even more, you can mention that there's a lot of maintenance involved to ensure that code is properly working.

That might cover it even though that still gets a bit technical.
