ROUTE B — UPGRADE · HUB
Technician →
principal engineer
The gap between a technician and a principal engineer isn't years served — it's systems depth, incident judgement, and whether people trust you when the room goes loud. All three can be built deliberately. That's what this route is for.
The ladder, honestly
WHAT ACTUALLY MOVES YOU UPKnow the systems cold
Power from grid to rack, cooling from plant to chip, controls, fire, life safety. Not vendor-course knowledge — the "explain it on a whiteboard during an outage" kind.
Own incidents properly
Anyone can follow an EOP. Promotions go to the people who write better ones afterwards — clean root-cause analysis, honest post-incident reports, fixes that stick.
Make yourself legible
CVs that speak hiring-manager, interview answers structured around real scenarios, and a track record you can actually evidence. Quietly competent doesn't promote; documented competent does.
