The solution is to separate "we use" from "we're looking for". Eg, a job post can say:

We use kafka, big-scale-databigness, BuzzwordDb, and CoolFramework. We're looking for smart engineers with an open mind and a commitment to building to high quality, robust systems. Minimum qualifications:

* Several years developing user-facing web applications * Experience with OOP in a language like Java, C#, Smalltalk, or similar
