My team is a couple dozen folks who typically dive into issues relating to internal challenges governments have wrangling their data into shape so they can make decisions. We've worked with NYC on their PPE crisis, Pennsylvania on hospital capacity tracking, Oakland on homeless encampments, and several others. Sometimes it's a quick python script to automate data ingestion, other times it's a complete web app.
In our case, most of it is private/internal, so it's not sexy work, but it really feels like we're having an impact.
