For context, I joined last month and am an entry level software engineer. I was working on a feature for an entire continent and we realised during validation on the release call that there was a bug in my code which was not spotted earlier in the code review process. I feel really disappointed; even though my manager and teammates have assured me it’s not a big deal, I still think it paints a bad impression of me. How do I come back from this?
(Note: I had ChatGPT ingest my taro profile, and give out this response)
Every engineer, at every level, has shipped a bug that made it to production. It’s part of the job. The fact that your manager and teammates aren’t making a big deal out of it should tell you something: This happens. What matters is how you respond.
You already acknowledged the mistake—that’s step one. No need to keep beating yourself up over it. Instead, shift your focus to learning and improving.
Instead of just feeling bad, ask yourself:
Your reputation isn’t built on one mistake—it’s built on patterns of behavior over time. Engineers aren’t judged by whether they make mistakes; they’re judged by:
Take what you’ve learned, apply it, and keep shipping. No engineer—no matter how senior—writes perfect code all the time. What separates great engineers is their ability to iterate, improve, and move on.
This won’t be the last bug you introduce. But if you use this as a learning opportunity, you’ll come out of it as a stronger engineer—and that’s what really matters.
Don't worry about it too much - You are a new junior engineer, and your team seems cool with it. Stressing out over this will just hurt you over the long-term as you second-guess every single decision you make.
Your main goal now is to learn from the experience. Think about how you could have caught this error earlier and more proactively. Learn how do that here: "How to turn a string of silly mistakes into a mature positive outcome?"
As a tech lead, the making of the mistake didn't matter to me that much - We're all human after all and do dumb stuff all the time. What mattered is how the engineer responded to the mistake. If they feel bad about it and I can see them introspecting and trying to grow from it, I was happy. If they didn't care about it and just moved forward nonchalantly - That's when I got mad.
