Людина відмовилася працевлаштуватися на цій посаді.

It is feminine because людина is a grammatically feminine noun in Ukrainian.

In the past tense, Ukrainian verbs agree with the subject in gender and number, so:

• людина відмовилася = a person refused
• not людина відмовився

This does not always mean the real person is female. It means the noun людина is feminine, so the verb matches it grammatically.

Людина means person or human being.

In this sentence, the most natural English equivalent is usually person. Depending on context, it could be:

• a person
• the person
• someone

Ukrainian has no articles, so людина by itself does not tell you whether English should use a or the.

The ending -ся is a very common Ukrainian verb ending. It often has a reflexive or middle meaning, but it does not always translate as oneself.

Here:

• відмовитися = to refuse
• працевлаштуватися = to get employed / find employment

In працевлаштуватися, the -ся helps make the verb mean to become employed oneself. Without -ся, працевлаштувати usually means to employ someone.

So:

• працевлаштувати когось = to employ someone
• працевлаштуватися = to get employed

With відмовитися, the -ся is just part of the normal dictionary form of the verb.

Because Ukrainian often uses the structure:

відмовитися + infinitive

to mean to refuse to do something.

So this sentence is built like:

• відмовилася = refused
• працевлаштуватися = to get employed

Together: refused to get employed / refused to take employment

A similar pattern:

• Він відмовився говорити. = He refused to speak.
• Вона відмовилася їхати. = She refused to go.

Працевлаштуватися means to get employed, to find employment, or in some contexts to take up employment.

It is understandable and correct, but it sounds fairly formal or bureaucratic. You often see it in official, administrative, or HR-style language.

More everyday alternatives are:

• влаштуватися на роботу = to get a job
• влаштуватися = to find work / get settled into a job

If the point is specifically accepting a position, Ukrainian often uses:

• обійняти посаду = to take/hold a position

So the sentence has a somewhat formal tone.

Цій посаді is locative singular.

Breakdown:

• ця → цій
• посада → посаді

So:

• на цій посаді = in this position / in this role

The preposition на can take different cases depending on meaning. With the locative, it often describes being in a place, role, or situation.

It is understandable, but many speakers would find на цю посаду more natural after a verb like працевлаштуватися, because the meaning is closer to moving into / taking the position.

So compare:

• на цій посаді = in this position, while in this role
• на цю посаду = into this position, for this post

Because of that, a more idiomatic version might be:

• Людина відмовилася працевлаштуватися на цю посаду.

And if you want a very natural way to say refused to take the position, you could also say:

• Людина відмовилася обійняти цю посаду.

So the original sentence is understandable, but it sounds a bit formal and slightly less natural than those alternatives.

Both verbs are perfective:

• відмовитися → відмовилася
• працевлаштуватися → infinitive perfective

This gives the idea of a single completed event:

• one refusal
• about one possible act of becoming employed

If you used imperfective forms, the meaning would shift toward an ongoing, repeated, or process-like idea:

• відмовлялася працевлаштовуватися

That could suggest repeated refusal, hesitation over time, or a more extended situation.

So the original sentence sounds like one definite refusal.

Yes. Ukrainian word order is more flexible than English word order.

The original order:

• Людина відмовилася працевлаштуватися на цій посаді.

is a fairly neutral way to present the information.

If you move parts around, you change the emphasis, not usually the core meaning. For example:

• На цю посаду людина відмовилася працевлаштуватися.

This puts more focus on the position.

For learners, though, the original order is the safest and easiest to understand.

Because Ukrainian does not have articles like a and the.

Instead, definiteness is shown by:

• context
• word order
• demonstratives such as цей / ця / це

In this sentence, цій already means this, so the phrase is clearly definite:

• на цій посаді = in this position

That is why Ukrainian does not need a separate word for the.
