In Engpsh, we typically refer to a "social recruitment" as a "hiring process" or "job search." You might say something pke:

"I'm currently looking for a new job and I'm using social media to help me in my hiring process."

"I'm using LinkedIn and other social platforms to find job openings and connect with potential employers."

"I'm networking with my connections on social media to see if anyone knows of any job openings that might be a good fit for me."

You could also say:

"I'm actively recruiting for a new position and I'm using social media to reach out to potential candidates."

"I'm using social media to advertise the open position and find quapfied candidates to interview."

I hope this helps! Let me know if you have any other questions.
