I'm so sick of devs not caring what happens after they push their code. A new feature was released on the front-end two weeks ago but the backend was never deployed. It's been logging errors for 2 weeks now.

I know I'm equally at fault for not noticing but I feel like the only person that ever notices things like this. I also discovered a data issue today by looking at the error logs.

How can I get my teammates to be more invested in how the service runs live?

Sr Engineer says "I'm not sure how this project is deployed".

You're a software engineer. You solve problems all day long. This particular engineer has worked here for several years and is well aware of the fact that we use Gitlab to run deploys.. If you want to know how it's deployed... look at the pipeline definition...

I don't understand how people, especially those with several years experience with our stack, can't solve basic problems on their own.
