How to Hire a Head of Engineering as a First-Time Founder

The Head of Engineering hire is one of the most consequential hires a technical founder makes — and one of the most commonly delayed and mishandled. This guide is for technical founders preparing to hire their first engineering leader.

When Is the Right Time?

The signal that you need a Head of Engineering: you are spending more than 40% of your time on engineering management tasks (1:1s, code review coordination, sprint planning, hiring) and less than 60% on technical architecture, product strategy, or customer-facing work. If engineering management is consuming the majority of your time and you are the CTO or founder-CTO, you need a Head of Engineering.

The wrong reason to delay: 'I want to stay close to the technical work.' You can remain architecturally involved with a Head of Engineering in place. In fact, you will be more effective technically when you are not also managing 8 direct reports.

The Two Head of Engineering Profiles

The player-coach (right for 10–30 person engineering teams)

A player-coach Head of Engineering contributes technically while managing the team. They write code (20–40% of their time), conduct code reviews, make architectural decisions, and manage 5–8 direct reports. This profile is right for companies where the engineering team is small enough that a manager who does not code loses technical credibility quickly.

The full-time engineering manager (right for 30+ person engineering teams)

A pure engineering manager who does not write production code, focused on: team building and management, process and delivery excellence, cross-functional coordination, and hiring. This profile is right for larger teams where the management overhead alone is a full-time job. Be explicit in the job posting about whether coding is expected — misalignment on this point is one of the most common reasons Head of Engineering hires fail.

What to Look For

• Has managed engineers before (not just been a senior engineer) — the leap from senior engineer to engineering manager is real and candidates who have not made it often struggle
• Has scaled a team through at least one significant growth phase (from 5 to 15 engineers, or 10 to 30) — the structural changes required at each growth phase are non-obvious without having lived them
• Has a communication style that works with your non-technical co-founders and leadership team — engineering translation to business stakeholders is a critical part of the role
• Has opinions about process and has implemented them — vague 'we should improve our processes' answers are not the same as 'I introduced a sprint structure that reduced our escape defect rate by 40%'
• References from engineers they have managed, not just peers and managers above them — former direct reports give the most accurate view of management quality

The Interview Process for a Head of Engineering

Round 1: Founder / CEO screen (45 min)

Assess: career trajectory, motivations for wanting this role at this stage of company, communication style, and first impressions on leadership presence.

Round 2: Technical depth interview (60 min, conducted by you or a technical advisor)

Walk through a real technical decision in their past. Ask: 'Walk me through an architectural decision you made in your last role that you would make differently today.' Then: a system design question appropriate for your product complexity. You are evaluating: depth of technical thinking, ability to communicate architectural reasoning, and intellectual honesty.

Round 3: Engineering management interview (60 min, conducted by an advisor who has managed engineering teams)

Ask: how did they structure their team and why? How did they handle an underperforming engineer? How did they prioritize between shipping features and paying down technical debt? What is their approach to code review culture? These questions reveal management philosophy and experience.

Round 4: Team meet (30 min each with 2–3 current engineers)

Current engineers assess: would I want to be managed by this person? Do I trust their technical judgment? Do they ask good questions about our current work? Engineers' instincts about management candidates are often more accurate than the formal interview.
