When you're talking about the title "Junior Developer" it depends on who you work for, and who's making the decisions. When you're talking about skill-wise, it depends very much on the individual. I've worked with some who are definitely not "junior" after less than a year, and I've worked with some who are definitely "junior" after more than 10 years. It comes down to aptitude and a willingness to learn on your own, especially early in your career. Answer from redneckrockuhtree on reddit.com

r/webdev on Reddit: How long to go from Junior to Senior?
July 15, 2019 -
I started my first job as a junior developer 3 weeks ago and I'm looking to get promoted to senior. How long did it take for those who have done it? I've been told that it's all about time, then I got told its all about experience?
I'm looking to become a senior in 2 years, what kind of things can I do to speed up this process? I currently know PHP, C#, HTML, CSS, JS, and VueJS. I feel like this is a strong start, where do I go to now?

I've been told that it's all about time, then I got told its all about experience? It's relative to the company you work at. If you sit down 10 different people, a mix of devs and managers, and ask them what defines a junior dev vs a senior dev, you'll probably get 10 different answers. Some companies will promote you to senior based only on time; this can be a blessing or a curse for some folks. If you aren't great at programming, this is a blessing because you'll become a senior through butt-in-chair time alone. You won't actually be able to do any work someone would expect of a senior at other companies, but you'll have the fancy title. Alternatively, it can be a curse because if you progress faster than their timeline, you'll be someone capable of doing mid level work while still considered a junior dev, and senior level work while still listed as mid. Others base it off of experience/capability. I fall into that bracket. My personal definition is this: Junior developer generates more technical debt than they resolve. They require supervision and mentoring in their day to day work in order to remain on course with the prescribed architecture. Mid level developer evens out, generating and resolving similar levels of technical debt. They can work without supervision on normal day to day tasks while remaining on course with the prescribed architecture, though supervision may be needed for newer/more complex projects. Senior level developers resolve more technical debt than they generate. No supervision is required to remain on course with prescribed architecture, or to come up with new architecture as needed. Able to supervise/mentor mid and junior developers as needed. In this regard, someone could have 20 years in the field and I'd consider them a mid level developer if they meet the above definition. A lot of folks don't like that, so some folks tend to focus more on time than skill when it comes to it. As for how long it takes? That depends on a mix of your ability to grow/learn, your company's willingness to promote/reward growth, and/or your willingness to shift jobs to move up the ladder as needed.

Don't get caught up so much on titles. Focus more on being a great well rounded developer. I've interviewed at a lot of places and I've noticed that every place has their own definition of what a "senior" developer is. Whether you're senior, mid, or junior, you'll be doing similar work. For what it's worth, I've seen "senior" developers that are really great coders and I've seen "senior" developers that could barely code their way out of a bag.

Key factors include: company promotion culture, individual performance, market conditions, and continuous skill development. High performers with strong technical and leadership skills can advance faster.

What skills do I need to become a senior software engineer?
Senior engineers need both technical depth and leadership skills. Technical requirements include: system design and architecture, performance optimization, security best practices, and expertise in multiple technologies. Leadership skills include: mentoring other engineers, influencing technical decisions, collaborating across teams, and connecting technical work to business outcomes. The ability to communicate complex technical concepts to non-technical stakeholders becomes crucial. Many engineers underestimate the leadership component and focus only on coding skills.

r/cscareerquestions on Reddit: When does a junior developer stop being junior?
November 20, 2014 -
It's more of an open-ended question, but I've seen some jobs that aren't marketed as "junior" yet seem well within the grasp of anyone half decent from college. I've also seen some "junior" developer positions that have some considerable requirements that probably only a few years of industry and specialization would give you.
In essence, what makes a junior developer vs what makes a regular or senior developer?

So first off, I'll say that I've worked with really smart and capable junior devs and nearly worthless "senior" devs so having the title doesn't actually mean much, depending on where you work. What I EXPECT though is something like this: Junior: Very little or no experience, requires a lot of hand holding and has to spend a lot of time learning tools, best practices, etc. Does not make any high level design decisions and is not a SME at anything. Mid-Level: A few years experience. Can get up and running into a productive state on a project pretty quickly and can be trusted to take a task and run with it on their own. Probably doesn't make many high level design decisions alone but is certainly included in the discussion. Senior: Several years experience. Has many successful and failed projects under their belt. Can not only take a task and run with it but can determine new tasks/issues/refactorings that need to be addressed and resolved. Takes initiative to do these things without anyone else having to tell them to do it. Can take other junior level engineers under their wings and help develop them. Makes high level design decisions, knows how to do the research to make these decisions well and probably also pulls from their experience to make these decisions.

This kind of question doesnt have a good answer. Many companies have a different interpretation of what “Senior” means. A senior software engineer at one company could be considered a junior dev at another. The levels that are attached to some like I, II, and III are even more arbitrary. So depending on what company this is, this can be anywhere from 0 years to 10 or more.

It took me 8 years to Senior. Then two as lead. 5 as EM. 5 as Director. And now I’m a VP.
Having said the above, every org is different. In the orgs I’ve been a part of 8 for senior is pretty good not exceptional. The bar was high, principal engineers were very rare, and the seniors were all excellent. But I’ve seen some acquired companies that basically place everything who isn’t bad into a senior dev role.

Top answer 1 of 5

It doesn't matter what you consider yourself to be, it's what others know about you. If you are a whiny-ass Jr. programmer that can't get anything done by himself, can't code his own way out of a paper bag, and has buggy, sloppy code others have to compensate for, then you will never be senior. If you show initiative, get stuff done, help others, continuously advance your knowledge, write code the runs the first time, and show initiative, people will start respecting you, and the advancements shouldn't be too far behind. Just keep at it.
