curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);

Answer 1

Usually to send post variables i use : the http_build_query function.
$url = "http://xxxxxx:8000/api/employer/login";
$post = ['lang'=> "593f973dea53161779dd5660",'password'=> "amit123d"];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);
It works better.

Answer 2

first check the request whether send post field or not.
$post = ['lang'=> "593f973dea53161779dd5660",'password'=> "amit123d"];
$ch = curl_init();
$url="https://httpbin.org/post";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);
the site: https://httpbin.org/ will response the post field if the post data exists.
I think the problem may occurs the nodejs side. Does it check the post field rightly ?
from my experience your code is right.
