La vacante necesita un historial profesional.

Because vacante here is a feminine noun meaning vacancy or job opening.

So Spanish uses the feminine article la:

• la vacante
• una vacante

Even though vacante can also be an adjective in other contexts, in this sentence it is being used as a noun.

Here, vacante means an open position, vacancy, or job opening.

So la vacante is not the empty state itself, but the available post/job.

In Spain, you will often also hear:

• puesto
• puesto vacante
• oferta de trabajo

Depending on context, vacante can sound a bit formal or HR-related.

Necesita is the third-person singular present tense of necesitar.

The infinitive is:

• necesitar = to need

And the present tense is:

• yo necesito
• tú necesitas
• él/ella/usted necesita

Since the subject is la vacante (singular), the verb must also be singular:

• La vacante necesita...

Yes, Spanish can use necesitar with things like jobs, positions, applications, or situations, even when the subject is not a person.

So grammatically, La vacante necesita un historial profesional is fine.

However, in real usage, many native speakers might find requiere more natural in this kind of formal context:

• La vacante requiere un historial profesional.

That often sounds more like HR/job-ad language.

Because historial is a masculine noun, so it takes un.

• un historial
• el historial

This can be confusing because some English speakers expect words ending in consonants to be unpredictable, and that is true to some extent—you just have to learn the gender with the noun.

Here the correct combination is:

• un historial profesional

It means something like professional history, work history, or employment record.

It refers to a person’s background in work or career terms.

Depending on context, English might translate it as:

• work history
• employment history
• professional background
• track record

It is not always exactly the same as CV/résumé, although in some contexts the ideas overlap.

Not exactly.

• currículum = CV/résumé, the document itself
• historial profesional = your professional/work history, meaning the background or record

So if a company wants the actual document, Spanish would more commonly say:

• La vacante requiere un currículum
• Se debe enviar el currículum

If it means previous experience or background, then historial profesional makes sense.

Because in Spanish, adjectives usually come after the noun.

So:

• historial profesional = professional history

This is the normal order:

• noun + adjective

Putting the adjective before the noun is much less common here and would sound unusual.

Because profesional is an adjective, not a noun phrase introduced by a preposition.

So Spanish simply says:

• historial profesional

not

• historial de profesional

If you wanted a different structure, you might say something like:

• historial de trabajo
• historial laboral

But in your sentence, profesional is directly describing historial.

They might, but it sounds a little formal and slightly less natural than some alternatives.

More natural options in Spain could be:

• La vacante requiere experiencia profesional.
• La vacante requiere un historial laboral.
• Para la vacante se necesita experiencia profesional.

Why? Because a vacancy more commonly requires experience than needs a professional history.

So your sentence is understandable, but depending on the intended meaning, another version may sound more idiomatic.

Yes, and in many cases that sounds more natural.

• experiencia profesional = professional experience
• historial profesional = professional/work history

The difference is subtle:

• experiencia profesional focuses on the experience someone has gained
• historial profesional focuses on the record or background of someone’s career

In job ads, experiencia profesional is often the more common choice.

Yes, but it is often used in somewhat formal or specific contexts, such as:

• historial médico = medical history
• historial académico = academic record
• historial laboral/profesional = work/professional history

So it is a normal word, but it often appears in administrative, professional, or official contexts rather than casual conversation.

Yes. In Spanish, job ads often use impersonal structures.

A very common version would be:

• Se necesita historial profesional.
• Se requiere experiencia profesional.

This style is very common in notices and job descriptions because it avoids naming a subject directly.

For many learners, this is useful because Spanish often prefers se necesita or se requiere in formal announcements.
