You might want to consider Singapore Airlines/Singapore Airlines Cargo. The cargo side is actively recruiting. The pax side is trying to juggle the 380 delays and the introduction of the 773ER, so they are in pretty good shape and it's taking quite a while to get a response from them.
From what you originally wrote, I'd assume you would qualify for DEC on the 744F, which isn't too bad. Anyhow, if you want any further info, just PM me or respond here.
