الوظيفة الشاغرة مش بس مناسبة، كمان المميزات كويسة.

In Egyptian Arabic, the present-tense verb to be is usually left out.

So:

• الوظيفة الشاغرة مناسبة literally looks like the vacant job suitable
• but it means the vacant job is suitable

And:

• المميزات كويسة means the benefits are good

Negation is added with مش, so مش مناسبة means is not suitable.

This is very normal in Arabic with present-time descriptions.

This is a very common pattern meaning not only ... but also.

In this sentence:

• مش = not
• بس = only / just
• كمان = also / too

So:

• مش بس مناسبة، كمان المميزات كويسة
• literally: not only suitable, also the benefits are good

A very natural English equivalent is It’s not only suitable; the benefits are also good.

You will hear this pattern a lot in spoken Egyptian.

Because in Arabic, adjectives normally come after the noun they describe.

So:

• الوظيفة الشاغرة = the vacant job
• literally: the job vacant

This is the normal Arabic order:

• noun first
• adjective second

The adjective also agrees with the noun in gender, number, and definiteness.

Because الشاغرة is part of the noun phrase, while مناسبة is the predicate.

1) الوظيفة الشاغرة

Here الشاغرة describes which job we are talking about, so it acts like an ordinary adjective inside the noun phrase.

That is why both words are definite:

• الوظيفة = the job
• الشاغرة = the vacant

2) الوظيفة ... مناسبة

Here مناسبة is not part of the noun phrase. It is saying something about the job: the job is suitable.

Predicate adjectives in Arabic usually do not take ال.

A useful comparison:

• الوظيفة المناسبة = the suitable job
• الوظيفة مناسبة = the job is suitable

That difference is very important.

Because الوظيفة is a feminine singular noun, and the adjective has to agree with it.

So:

• وظيفة is feminine
• therefore مناسب becomes مناسبة

This is basic adjective agreement in Arabic.

You can think of it like this:

• masculine: مناسب
• feminine: مناسبة

Since the subject is الوظيفة, the feminine form is required.

Because المميزات is a non-human plural, and in Arabic non-human plurals are very often treated grammatically like feminine singular when followed by adjectives or predicates.

So:

• المميزات كويسة is natural
• even though المميزات is plural

This is a very common Arabic pattern.

Compare it with people:

• المرشحين كويسين = the candidates are good
  because candidates are human, so a plural adjective is used

But with things, benefits, features, books, houses, etc., feminine singular is very common:

• الكتب جديدة
• الحاجات حلوة
• المميزات كويسة

It is best described as a mix of Egyptian Arabic and more formal job-ad language.

Clearly Egyptian/spoken parts:

• مش
• بس
• كمان
• كويسة

More formal or standard-sounding part:

• الوظيفة الشاغرة

That kind of mixing is extremely normal, especially in:

• job ads
• company posts
• professional social media
• semi-formal speech

So yes, it sounds natural, even if not every word is equally casual.

In a job context, المميزات usually means benefits, advantages, or perks.

It can include things like:

• salary-related advantages
• bonuses
• health insurance
• transportation
• flexible hours
• training opportunities
• paid leave

So it does not just mean one small detail. It usually refers to the positive points of the job package as a whole.

It is natural, but it sounds formal.

You will often see وظيفة شاغرة in:

• advertisements
• official announcements
• HR language
• written business Arabic

In casual everyday Egyptian, people may use more conversational expressions such as:

• وظيفة متاحة
• في شغل متاح
• في فرصة شغل

So الشاغرة is correct and common, but it belongs more to a formal or professional register.

Because كويس / كويسة is one of the most common spoken Egyptian ways to say good.

So:

• كويس = masculine singular
• كويسة = feminine singular

It sounds natural and conversational in Egyptian Arabic.

A more formal or Standard Arabic style might use جيدة, but in everyday Egyptian speech كويسة is much more common.

كويسة is the feminine form of كويس.

A rough pronunciation is:

• كويس ≈ kwayyis
• كويسة ≈ kwayyisa

So the sentence uses the feminine form كويسة.

This matches the grammar of the sentence, especially since المميزات is a non-human plural, which is commonly treated like feminine singular.
