If you manage managers, growing them is one of your highest-leverage activities. A strong senior EM can grow 4–8 new managers over their career; a weak one produces dysfunction that ripples for years. The interview increasingly probes this skill at director-level loops.

## The new-EM transition

Engineers becoming managers face a transition that is hard to overstate:

- Output is now your team's output, not yours

- Coding time drops dramatically

- Identity from technical excellence shifts to people leadership

- 1:1s become the highest-leverage hour

- Calibration, performance management, hiring all new

Many engineers love the idea of management until they actually do it.

## The first 90 days for a new EM

Coach them through:

- Listen-first mode, don't fix things on day 1

- 1:1 with every report; build understanding

- Establish operating cadence (1:1s, standups, planning)

- Learn the calibration and review processes

- Understand the company-level context

## Common pitfalls of new EMs

### Coding too much

Comfort zone of the IC. Watch for: new EM coding 50%+ of the time, missing 1:1s, neglecting strategic work.

Coaching: explicitly limit coding time. "I want you below 25% IC work this quarter." Reward the management work in feedback.

### Avoiding hard conversations

Underperformance, conflict, performance reviews: new EMs often dodge these. Watch for: vague feedback to reports, no PIPs even when warranted, glossing over performance issues.

Coaching: practice the conversations together. Role-play. Provide a script for the first time.

### Trying to be friends with everyone

The peer-to-manager transition is hard. Watch for: avoiding feedback, refusing to address problems, drinks with one report and not others.

Coaching: distinguish friendship from professional respect. Build trust through fairness, not popularity.

### Over-engineering management

New EMs read too many books and try to apply every framework. Watch for: convoluted 1:1 templates, excessive paperwork, "let me think about this" delays.

Coaching: simplify. Pick 3 things that matter. Do them well.

## The 1:1 with your direct EM-report

Different from 1:1 with an IC:

- Less project status, more team health

- How are their reports doing?

- What management decisions are pending?

- Where are they stuck on a hard conversation?

- What support do they need from you?

Goal: develop their judgment, not give them answers.

## The skip-level relationship

You should know your manager-reports' reports. Quarterly skip-level 1:1s. Listen for:

- How is their manager doing?

- What do they wish was different?

- Are they getting career growth?

This gives you data your direct reports may not share.

## Co-running their first hard cycle

For a new EM's first calibration / performance review cycle:

- Walk through how to write reviews

- Sit in on calibration as observer

- Help draft promo packets

- Coach through delivering hard ratings

The investment compounds — by their second cycle, they are mostly autonomous.

## When the new EM is not working out

Sometimes the transition fails:

- They miss 1:1s repeatedly

- Reports complain to skip-level

- Team output drops

- They retreat into coding

Options:

- Direct feedback and coaching

- Move them back to IC (with face-saving framing if possible)

- Let them fail forward to a different role / company

Most companies allow IC-EM-IC moves, especially in the first year. Frame it as "this role wasn't the right fit," not "they failed."

## Promoting from within vs hiring external

Internal promotion: knows the team, faster ramp, cultural continuity. Risk: peer-to-manager dynamic, may lack management experience.

External hire: fresh perspective, prior management experience. Risk: longer ramp, may not fit culture.

Most healthy orgs do both. Aim for ~50/50 on EM hires.

## Frequently Asked Questions

### How long should a new EM take to be self-sufficient?

6–9 months for basic operations. 12–18 months to fully own their team's strategy and outcomes.

### What if my new EM is more senior than me technically?

Common. Your job is to grow their management, not their technical depth. Lean into your management experience; defer to them on technical questions.

### Should new EMs still write code?

Some, especially small teams. Cap at 25% of time. Drop further as team grows.
