I am writing this newsletter from the Singapore airport on my way back to Bangalore. Initially, the plan was to skip, but I got a great response on last Wednesday’s newsletter, so thanks for the motivation :D

Back to the topic,

Most senior engineers make the same mistake:

They mentor in 1:1 conversations only

That works for juniors, but at your level, it doesn’t scale.

The best senior engineers build what I call a Mentorship Flywheel

Mentorship Flywheel is a system where every mentoring moment creates long-term leverage

It is not about working harder
It’s about creating assets that teach, guide, and unblock people long after you’re in the room.

I am adding a quick exercise at the end of this article so you don’t procrastinate like me and can just start from today

Why Mentorship Needs a Flywheel

Think about the last few weeks:

Did you explain how to write a clear PR description (again)?
Did you show someone how to debug flaky tests (again)?
Did you answer “how do we deploy this service?” (again)?

If you’re repeating yourself, you’re not mentoring, you’re babysitting knowledge.

Senior engineers don’t just pass on knowledge. They multiply it.
And the Mentorship Flywheel is the engine that makes it happen.

The Mentorship Flywheel (4 Steps)

1. Teach (Live)

Every flywheel starts here: pair programming, code reviews, design discussions.

Live teaching is powerful because:

It builds trust quickly
It adapts to the learner in real time
It exposes gaps in the system (missing docs, inconsistent practices)

But here’s the trap: if you stop at teaching, you’ll always be on-call as the “human knowledge base.”

👉 Rule of thumb: If you explain something 3 times, it’s worth moving to the next stage.

✅ Example:
You notice that every new hire struggles with running integration tests locally. You’ve walked 3 different people through the setup in the last quarter. Instead of repeating it again, you decide: this deserves a doc

2. Document (Static)

Documentation is your first lever of scale.

The goal isn’t to create a “perfect wiki.” It’s to capture just enough so the next engineer can help themselves.

Tips for writing effective docs:

Keep them short (1–2 pages max)
Use checklists or step-by-step guides
Include examples and screenshots if helpful
Store them where engineers already work (Notion, Confluence, GitHub repo, internal wiki)

✅ Example: PR Checklist (steal this):

# PR Checklist
- [ ] Title explains the change clearly
- [ ] PR description includes:
   - Context (why this change is needed)
   - Approach (how it’s solved)
   - Trade-offs (what was considered/rejected)
- [ ] Testing steps provided
- [ ] Rollback plan mentioned (if risky)
- [ ] Reviewers tagged

Now, instead of you nagging about missing context, the checklist does the work.
