From Engineer to Engineering Manager

This is for you if

• You're a strong DevOps, SRE or platform engineer weighing the staff engineer track against engineering management
• You've just become a lead or manager of an infrastructure team and want a plan for your first 90 days
• You're the informal lead already and want the 1:1s, feedback, planning and on-call skills to do it properly
• You're preparing for engineering manager interview loops and need strong stories and answers

What's inside

• An honest staff/principal versus engineering manager comparison, with a track decision worksheet
• A 90-day plan: listening tour, team baseline, written assessment and two or three changes that stick
• 1:1 structure, a shared doc template and a question bank organised by purpose, plus GROW coaching
• Feedback with the SBI model from the Center for Creative Leadership, performance reviews, calibration and growth plans
• Hiring: job descriptions, current Ontario posting rules, structured interviews, anchored scorecards and bias reduction
• Delivery for infra teams: honest capacity, a Run/Improve/Build toil budget, OKRs, intake, managing up, budget and headcount
• On-call health reviews, incident leadership, error budgets as a negotiation tool, platform-as-product and DORA metrics used carefully
• Psychological safety (Project Aristotle, Edmondson), burnout, difficult conversations and fair, HR-partnered underperformance handling
• The manager interview loop with STAR stories, 27 questions with strong answers, and a templates appendix

After this guide you can

• Decide between the staff engineer and engineering manager tracks with evidence, not a vibe
• Run your first 90 days with a listening tour, a written assessment and measurable changes
• Hold 1:1s, give SBI feedback and write growth plans that people actually act on
• Plan a quarter with an explicit toil budget, outcome-based OKRs and a visible cut line
• Keep on-call sustainable and use error budgets to settle reliability debates with data
• Walk into an engineering manager interview loop with rehearsed STAR stories and strong answers
