Cleared to taxi to end of Runway 26L upon landing and then into the taxiway extension of 26L; right turn on Taxiway J to the ramp.  Taxied to the area adjacent to the intersection of taxiways J; G; K; and H; but could not see a sign for it from the taxiway extension; saw F ahead; so we stopped.  Asked Ground for different taxi instructions since we couldn't make the over 90 degree right turn onto J from where we were.  Received taxi via F and back to J from Ground.Signage for Taxiway J is behind you when taxing westbound off the end of Runway 26L. We were unfamiliar with the layout at the junction of taxiways G; H; K; J and the extension of Runway 26L.  Taxiway J sign is up the taxiway and facing slightly away from you while headed west on Runway 26L extension.  It was nighttime; dark with good visibility; but neither of us saw the sign for J.  We stopped abeam the intersection of H; J; and K but couldn't make the turn for J; so we stopped and requested different clearance.Better signage for Taxiway J alongside the taxiway extension of Runway 26L.  More familiarization with the layout and better briefing of the difficulty in identifying the turn for J by me and the FO.  The area is a hot spot for incursions and we had talked about it but neither of us saw a sign for J.  The sign for J is well up the taxiway and is slightly behind you once you are abeam the intersection of those 5 taxiways.
Air carrier Captain stated that the sign for Taxiway J was not visible at night due to the sign's placement and angle at ELP airport.
