This seems pretty common in our field. There will always be people who put down others to try and make themselves look good because that's how every corporate culture is incentivized to run. I have not seen any serious attempts to address core issues like this at any company. HR only reacts to protecting the business, and that means retaliation for speaking up usually, especially if the bad coworker is a boss favorite. Also, managers will blame you even if you bring up an issue, but it's not slated into the sprint. Then when the issue blows up in production, they'll say you should have worked faster to address it previously when it was noted, or that you should have placed more emphasis on it during the sprint planning when really, the final decision wasn't in your control in the first place. I've seen this happen on my teams in the past. Tech is just all around toxic, and these things happen quiet frequently at larger companies.
