From what I've seen of the pharmaceutical statistics research at Oxford, you might be interested in PA's Life Sciences & Healthcare Practice. Their work includes using optimization, discrete event simulation, and Bayesian networks to improve resource allocation & project selection & timing in drug discovery and development. I help out on this sometimes and in my (rather biased) view it is truly cutting-edge and with huge potential impact. It is also enjoyable and puts my mathematics PhD to good use. More widely, most large consulting firms will have good-sized pharmaceutical groups. Also, many will hire PhDs with relevant specialist skills like yours a rank or two ahead of graduates, or put them on a fast-track.
