Those job ads are both better than my current position. £40k for cross-platform C++ desktop app with both multi-core and distributed parallelism. PhD required. GPGPU experience preferred (notice that it's not CUDA experience because some users have AMD cards). Now, with two consecutive promotions, I could bump my salary up to £50k. Of course, to qualify for the second of those promotions, I need to receive personal commendations from three different professional organizations across at least two different countries.
