Go to the HN Who is Hiring thread, make a bookmark, change the title to "HN Job Searcher" and replace the address with the following (paste in):

javascript:void(function(){ var a=prompt('Enter keywords:').split(' ');var c=document.getElementsByClassName('athing');var r=[];for(var i=0;i<c.length;i++){ var m=0; for(var j=0;j<a.length;j++) { if (c[i].innerText.toLowerCase().indexOf(a[j].toLowerCase()) > -1) { m++; } } if (m==a.length) { r.push(c[i])} };var z=function(x, y) { x.onclick=function(){y.scrollIntoView();}}; for(var i=0;i<r.length;i++) {r[i].style.backgroundColor='orange';z(r[i], r[i+1])};r[0].scrollIntoView();}())

Then open the bookmark as you normally would while on the thread. In the popup that appears type your job criteria, e.g. "javascript remote", and the results are shown. Tap on a result to go to the next one. Reload the page and open the bookmark again to search again.
