Orbital ergonomics

From Memory Alpha, the free Star Trek reference.

Orbital Ergonomics was the application of scientific information to the design of objects, systems and environments for humanoid use while in orbit. Some people assigned to Orbital Ergonomics were M. Moore and M. Keating. (Star Trek: Enterprise set artwork)

Orbital ergonomics personnel are not listed on starships after Enterprise (NX-01), however this does not mean that this job did not exist after this time.
