Intel is expected to go into manufacturing on its first 10-nanometer products during the second half of 2017. For simplicity, let's assume that volume availability of 10-nanometer product doesn't happen until January 2018.Intel has said that it plans three waves of 10-nanometer technology: 10-nanometer, 10-nanometer+, and 10-nanometer++. If Intel keeps to an annual product launch cadence, then we should see volume availability of the first 10-nanometer+ products in January 2019, and the first 10-nanometer++ products in January 2020.
Based on this cadence, which is admittedly probably on the pessimistic side, the first products based on 7-nanometer would be expected to launch in January 2021 -- a bit earlier than the 2022 time frame given in the job listing.
What Intel could be planning, then, is to introduce substantially enhanced chip designs a year after the first 7-nanometer products, which could very well be modest updates to the final 10-nanometer++ products. In fact, Intel's product cadence is now referred to as "Process, Architecture, Optimization," so fundamentally new architecture products on 7-nanometer could, indeed, arrive in January 2022.
