The 5-step process
Each step has a clear owner, a typical duration and a deliverable. Run it like a sprint.
- 01
Define the role and must-have skills
Day 0 · 1 hrAgree the 3–5 non-negotiable skills before sourcing. For a head of engineering, that's typically Multi-team Leadership, Manager Coaching, Technical Strategy, Hiring plus demonstrable experience shipping production systems.
- 02
Decide on level, comp, and working pattern
Day 0 · 30 minMid-level head of engineerings earn around £140k–£175k; senior hires reach £185k–£250k. Confirm hybrid/remote expectations upfront - it's the single biggest deal-breaker on offers.
- 03
Source vetted candidates
Day 1Skip cold sourcing. Haystack matches you with pre-vetted head of engineerings actively interviewing, with skills, salary and notice period verified upfront.
- 04
Run a focused 2–3 stage process
Day 2–10Keep it tight: 30-min intro, technical deep-dive, and a final round with team and leadership. Avoid take-homes longer than 2 hours - top candidates won't engage.
- 05
Reference, offer, and onboard
Day 10–14Move fast on offer once a decision is made. Senior head of engineerings often have multiple processes running; a 24–48 hour offer window is the new normal.
£140k–£175k
Mid-level base
Anchor your comp band around the mid-level number. A senior head of engineering reaches £185k–£250k; juniors start near £105k–£130k. Add ~10–15% for London and Berlin, and 25–40% for SF and NYC, where total comp dominates base.

Common mistakes that kill head of engineering hires
Vague job description
Skills like "Multi-team Leadership" need years of experience and context. Specify it.
Too many interview rounds
Top candidates drop after the 3rd. Cap at 3, including final.
Lowballing on offer
Internal salaries go stale fast. Benchmark every 6 months - not yearly.
Skipping references
Live-coding catches what dialogue won't. Always do at least one paired session.
Slow offer turnaround
48 hours after final round is the upper bound. Faster wins the candidate.
No defined scorecard
Hiring 'gut feel' alone leads to inconsistent decisions across panels.
What a great head of engineering owns
Use this as your interview scorecard. Score each candidate 1–5 per item; calibrate as a panel.
- Lead a group of engineering teams
- Coach engineering managers and tech leads
- Own technical strategy for the group
- Drive cross-team delivery
Deep dive
The head of engineering hiring playbook
Head of Engineering specialist or generalist - which should you hire?
The honest answer depends on the half-life of your head of engineering surface area. If you expect to keep investing in Multi-team Leadership and Manager Coaching work over the next 18-24 months, a specialist head of engineering will out-deliver a generalist on day-30 throughput and stakeholder confidence.
If your team is under ten people, or head of engineering responsibilities are spread across two or three roles already, hire a strong generalist who has shipped this work in anger at least twice. The cross-disciplinary pattern recognition will pay for itself the first time priorities collide.
On Haystack we surface both - filtered by whether the candidate self-identifies as a head of engineering specialist and verified against their last two roles. Expect to pay around £140k–£175k for a mid-level UK hire, scaling toward £185k–£250k for senior.
What strong head of engineerings actually bring
A great head of engineering is not the one with the longest CV - it is the one who has owned a hard Multi-team Leadership call and changed how they work because of how it landed. Across the management hires we have placed in 2025-2026, the same patterns keep showing up.
- Active mentorship of at least one other head of engineering or adjacent role - usually a junior - within the first quarter.
- Versioned, observable head of engineering work - measurable outputs, structured logs of decisions, and a clear rollback path on every change.
- Documented trade-off notes on the calls they made, including the option they rejected and why.
- An opinion on what NOT to do with Multi-team Leadership, backed by an example where adding it would have hurt the team.
Red flags when interviewing head of engineerings
Every discipline has its own pattern of plausible-sounding answers that fall apart in production. For head of engineerings, these are the patterns that most often correlate with a six-month regret hire on the employer side.
- Cannot name a single head of engineering project where they removed scope rather than added it.
- Defines "senior head of engineering" purely by years of experience, not by the scope of decisions they own.
- Lists Multi-team Leadership on the CV but cannot describe a single trade-off they hit in production - all framework, no friction.
- Treats the head of engineering role as a job title rather than a problem to solve - no opinion on what they would change about how the discipline is typically practised.
What to expect in the first 30 days from a Haystack head of engineering hire
By week one, the new head of engineering should have shipped a small, low-risk artefact to production or a stakeholder - a docs fix, a small process change, a first review on someone else's work. The goal is to validate the loop, not to ship anything heroic.
By week two, the head of engineering is shadowing the active workstreams, attending standups in observe-mode, and asking pointed questions about why specific decisions were made. If they are not asking those questions, the hire is going to plateau.
By day 30, they own one cleanly-scoped slice of the head of engineering surface area, have published a public ramp-up doc, and are the named point of contact for stakeholders inside that slice. Every Haystack employer gets a structured onboarding template, so you are not reinventing the playbook each hire.
