I am a mid-level engineer at an HFT company. I've been with my current company for around 7 months and another similar one for 2.5 years previously. My biggest career issue so far has been poor attention to detail, which leads to me to always miss small mistakes I make.
For instance, I always review my own PRs myself before sending to reviewers, and clean up plenty of issues I notice myself. But then my reviewer will point out some kind of bug, or something I forgot to do, and in retrospect it will be immediately obvious to me. Alex often mentions the importance of being able to get most of your PRs accepted in one attempt, but for anything > 30 lines this simply feels like a pipe dream because I am so terrible at noticing things until it's too late.
(For the record, I'm very thorough with test coverage, but when I simply forget to implement something, I of course forget to test it too).
Another more specific example is that our process of verifying features in production is sometimes a bit involved, and requires changing config in several places. I knew what to change, did so and tested everything, then told my manager the feature had been verified. Later on he was looking at the configs (not sure whether he did it to check my work or for some unrelated reason) and pointed out that I did not actually set everything as I intended to, and therefore the feature wasn't verified correctly. I realized mistake I made (ran a command to change a bunch of files in the wrong directory) but only after the fact, and it cost me embarrassment and extra work.
I think I'm quite good at the other aspects of software engineering: coming up with impactful ideas and executing on them independently, picking up domain knowledge and areas of the codebase quickly, fixing bugs (my own or others'), presenting on my work, etc. So I've been able to eke out "meets" and even "exceeds" reviews at my first job because I had significant impact despite blundering all over the place.
But my deficiencies in this area make me fearful for my career, as I am always worried about making just enough mistakes to get PIP'd or fired. Furthermore, we don't have levels here, but I doubt I can make it to the equivalent of Staff or even the senior level with this kind of defect.
Does anyone have advice on how I can "train my brain", as it were, to improve at this ASAP and make sure I don't go down the wrong trajectory? Thanks!
