After adjusting for purchasing power parity (PPP), London's salary is worth $93K in US purchasing power terms, versus $123K for Seattle. This means Seattle offers better real purchasing power for this role.
PPP adjustment accounts for differences in local prices — for example, housing costs 3x more in San Francisco than in Warsaw, so a San Francisco salary needs to be much higher to provide an equivalent standard of living.
