This is an interesting feat with some situational utility, but I feel like it is missing the key problem with mechanic medics: when you're investing heavily into Int and Dex to make your main abilities and combat work, you probably don't have a lot of room left over to invest in Wisdom.
This is a problem because 1e Starfinder had Medicine as an Int ability, but the Pathfinder 2 paradigm of wanting Clerics to be good nonmagical healers as well now infests SF2.
I think this would be easily fixed by giving the level 1 feat High Tech Medic the ability to use Intelligence for Medicine. This would let mechanics (especially multidisciplinary biotech mechanics) actually be good doctors while keeping Medicine as a Wisdom skill for Mystics.
It also gives a sort of Biohacker feel as Biohackers could basically choose if their main ability score for any science-based check was Int or Wis.
Anyway, that's my two cents after making my first Mechanic using the playtest rules.
The Pathfinder 2e chirurgeon alchemist takes this even further: it straight-up substitutes Crafting for Medicine completely, meaning it can forego both WIS investment and skill training.
It's been a while since I looked at the playtest, but I believe the mechanic got some extra skill boosts, so maybe they don't need it, but still I think SF2 could use another healer besides mystics and certain envoys.
