What are the different levels of software engineers at Google?

Junior Software Engineer

Junior software engineer is the start of the software engineer title ladder. When a software engineer first gets started professionally, that person is (usually) a junior software engineer.

The title junior software engineer generally signifies that either:

the software engineer's skill level is still unknown or

that it is known and the software engineer needs a lot of hand holding (from other software engineers) to complete any non-trivial amount of work.

(Even software engineers that show a lot of potential tend to start here, until they either get enough experience or demostrate competence at a higher level.)

Usually, in the short-term, junior software engineers have a negative impact on the productivity of a team (because of the hand holding). But long-term, when their skills and experience increase, they can be a good investment.

Intermediate Software Engineer

Like I already said, most people don't actually call people intermediate software engineers. "Intermediate software engineer" is usually shortened to just "software engineer". (Which can be a little confusing, when you want to talk about software engineers in general, without a title. But anyways....)

An intermediate software engineer is an engineer who can do work without any hand holding, but doesn't yet have the skills and experience to be a senior software engineer.

Typically, although an intermediate software engineer doesn't need any hand holding they still need someone to break down a high level task into smaller well-defined tasks for them to work on.

So, perhaps another way of defining what an intermediate software engineers is... an intermediate software engineers is a software engineer who can work on and complete a small well-defined task (but doesn't yet have the skills and experience to be a senior software engineer).

Also, intermediate software engineers tend not to have a full grasp of the software development life-cycle (SDLC) yet.

Also, intermediate software engineers tend not to understand the big picture.

Typically, an intermediate software engineer can get their code to work, but does not have the experience or knowledge to do the quality of work, from an architecture, maintainability and testability point-of-view, that you would expect from a senior software engineer.

Senior Software Engineer

A senior software engineer is capable of being given a high level (and often vague) task, and work completely independently on it and finish it.

I.e., a senior software engineer does not need their work broken down into small well-defined tasks for them; a senior software engineer can take a high level (and often vague) task and break it down into small well-definedtasks themselves!

Although senior software engineer could do it all the work on a project completely own their own and independently, they may have other software engineers help them with the project. Especially in times when it is preferable that the work be done faster. (Like if there is a deadline.)

Typically, a senior software engineer is aware of the full software development life-cycle (SDLC) and have good architecture skills such that things like maintainability and testability are addressed.

Typically, a senior software engineer is expected to provide production support (like waking up at 3:00am to fix some problem on production) and to help deal with company-wide concerns.

Typically, a senior software engineer can be trusted to work independently to solve most problems.

It should be noted that some companies stop at this title -- at senior software engineer -- and have no engineering titles above it. At these types of companies, there is a very broad range of skill wrapped into the senior software engineer title.

However, others keep on going with titles above senior software engineer; and so, so shall we.

Staff Software Engineer

Tabpear is a Software Technology Co., Ltd which has many domestic excellent  e-commerce platform R & D teams and mobile R & D teams. We divide the software engineer teams into several levels according to the project development experience. Level one is more than 3 years of development experience. Level two is more than five years of development experience. Level three is more than 10 years of development experience and Level four is expert team which has more than five participating in research projects, Invention patents and software copyrights of 6 or more, published in the core periodicals more than 10 papers. There is also a team ,working at cloud computing and service computing including four doctors, seven masters and 23 persons who have master's degree.
