You simply need to filter based on both id and jobid combination. To do that you can group data by jobid and search within that jobid
const arr = [{jobid: "atA3Qi4BJu01VrUasiSX", id: "I1bncvyBsjbu7ePdPvYt", firstName: "Krishnakumar K R", Title: "design job", empname: "Rakesh"},

Create a tmp variable to store the item already existed will decrease the loop, instead of search the whole array for each item in the array.

You can simply create a map from the array after filtering by jobid, which will contain unique values.
let map = {};
array.map(element => {
if(!map(element.id)){
map[element.id] = element;
}
})
After this you can take the values as Object.values(map). This will contain unique elements.
