Engineering Manager onboarding plan

What a strong ramp looks like for a new engineering manager. Week 1 universals + 30/60/90 day milestones, each with an accountable owner — manager, new hire, team, or HR.

Week 1

Get them productive on tools, oriented to people, and clear on what success looks like in their first 90 days.

1. 1Day 1: workspace + tooling set up before they arrive (laptop, accounts, Slack, email). New hire's first email should be 'everything just works.'Manager
2. 2Day 1: 30-min welcome with their manager — share the team's mission, their first project, and book recurring 1:1s.Manager
3. 3Day 1-2: meet & greet calls with 4-6 people they'll work with most. 15-20 min each, calendar-blocked in advance.Manager
4. 4Day 3: have them ship something small (a Slack post, a document, a tiny PR) — confidence-building, momentum-setting.New hire
5. 5Day 5: review the 30/60/90 plan together. New hire confirms it sounds achievable; manager confirms it's the right shape.Manager
6. 6End of Week 1: HR / People check-in. Surface friction (access issues, missing context, mismatched expectations) early.HR

Days 1-30

Listen, listen, listen. No big moves yet.

1. 11:1 with every direct report in the first 10 days. 45 min each, no agenda except listening.Manager
2. 21:1 with every peer manager + your manager's manager. Understand the org context.Manager
3. 3Read the team's last 2 quarters of planning docs, last 5 post-mortems, last 3 retros.Manager
4. 4Sit in on every existing team ritual (standup, retros, planning). Don't change anything yet.Manager
5. 5Day 30: write your 'what I'm seeing' summary for your manager. Capture observations before they get normalized.Manager

Days 31-60

Form hypotheses, make small low-risk changes, build trust.

1. 1Make 1-2 small process changes based on what you've heard (e.g., 1:1 cadence, retro format, planning tweak). Frame as experiments.Manager
2. 2Take ownership of one major team output (roadmap, hiring, key project). Be the accountable face for it.Manager
3. 3Have your first uncomfortable conversation — performance feedback, scope dispute, peer disagreement. Don't wait for it to escalate.Manager
4. 4Build your hiring bar: define the rubric, calibration sessions with team, before you make any hires.Manager
5. 5Co-author the next quarter's plan with your team — show how you think about prioritization.Manager

Days 61-90

Make your first material call. Own the team's outcomes.

1. 1Make your first material decision — a structural change, a hire, a re-org, a project pivot. Earn the team's trust by being right (or by handling being wrong well).Manager
2. 2Run your first full quarterly planning cycle.Manager
3. 3Own the team's headcount allocation. Trade-offs become real.Manager
4. 4Conduct your first formal 1:1 performance review.Manager
5. 530/60/90 retro with your manager. What's clear, what's still murky.Manager
