Every engineering ladder codifies mentorship as a core requirement for promotion. The expectation is that senior operators will seamlessly upskill junior hires while maintaining their own velocity. This is an economic impossibility. The system mathematically punishes the senior engineer for doing exactly what the guidelines demand.

The Uncounted Hours
Mentorship is structurally invisible. Spending four hours walking a junior developer through a legacy abstraction layer does not generate a Jira ticket. It does not show up on the weekly commit velocity report. When the quarterly review arrives, the manager looks at the metrics, sees a dip in feature delivery, and questions your impact. The institutional knowledge transfer is treated as a hobby, not a primary objective.
⸻
The Tragedy of the Competent
This creates a brutal incentive loop. The most effective mentors naturally attract the heaviest load of junior dependencies. Because they are patient and skilled at untangling complexity, the organization quietly funnels every struggling new hire onto their calendar. They are paying a massive operational tax simply for being competent. Meanwhile, the aggressively unsocial engineer who hoards context and refuses to pair-program maximizes their personal delivery metrics. The system promotes the hoarder.

The Defensive Guardrail
If you want to survive, you must budget your mentorship like capital. Do not distribute it evenly. Identify the one or two junior engineers who actually possess the capacity to absorb the context and replicate the output. Invest heavily in them, and build a protective wall against the rest. Use asynchronous documentation to deflect repetitive questions. Never sacrifice your critical path delivery to explain a git rebase.
⸻
Recognize that the organization will not defend your time. If you over-invest in teaching, you will be penalized for under-delivering. The survivor funds their mentorship strictly out of their surplus velocity, never their baseline. Teach selectively. Protect the core.
End.
