Junior devs on the other hand tend to be developers with little to no experience with some of the core technologies used within the role. Typically they'll require some help from more senior devs to get up to speed.
I've been a developer for over 10 years at this point and I'm not really sure I feel like a senior dev. Every week I'm reminded how much I don't know. There's definitely a huge variance in the abilities of senior devs. Some of worked with are been terrible while others have been indispensable to the team. It's always bothered me that variance wasn't reflected in pay or title.
Being competent enough to work independently is an extremely low bar for the distinction of being a senior in your field.
In most other industries that just means you’re not a trainee any longer.
For example my wife just entered the medical field doing administrative work. She’ll be a trainee for a full year. It will be a decade or more before she’ll be qualified to be in any sort of senior role.
I mean at the end of the day I don’t feel that strongly about it, but the problem is that when titles become meaningless it’s very hard to for example, communicate what role you’re hiring for, or who the right person to lead a new project is.
Titles aren't exactly medals or certifications, they just denote who to blame.
The software industry in particular has gotten really lax with titles, to the point that they mean next to nothing.
I get a laugh imagining a kid just a few years out of school explaining to people that they’re a “senior software engineer”. Anyone on the outside would assume they’re either full of shit or some kind of Doogie Howser.
