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 data, that's typically Data Strategy, Org Design, Analytics Leadership, ML Strategy plus demonstrable experience shipping production systems.
- 02
Decide on level, comp, and working pattern
Day 0 · 30 minMid-level head of datas earn around £135k–£170k; senior hires reach £180k–£240k. 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 datas 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 datas often have multiple processes running; a 24–48 hour offer window is the new normal.
£135k–£170k
Mid-level base
Anchor your comp band around the mid-level number. A senior head of data reaches £180k–£240k; juniors start near £100k–£125k. 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 data hires
Vague job description
Skills like "Data Strategy" 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 data owns
Use this as your interview scorecard. Score each candidate 1–5 per item; calibrate as a panel.
- Lead the combined data function
- Set strategy across analytics, engineering and ML
- Drive data-as-a-product mindset
- Partner with C-suite on data-led decisions
Deep dive
The head of data hiring playbook
Head of Data specialist or generalist - which should you hire?
The honest answer depends on the half-life of your head of data surface area. If you expect to keep investing in Data Strategy and Org Design work over the next 18-24 months, a specialist head of data will out-deliver a generalist on day-30 throughput and stakeholder confidence.
If your team is under ten people, or head of data 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 data specialist and verified against their last two roles. Expect to pay around £135k–£170k for a mid-level UK hire, scaling toward £180k–£240k for senior.
What strong head of datas actually bring
A great head of data is not the one with the longest CV - it is the one who has owned a hard Data Strategy 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.
- An opinion on what NOT to do with Data Strategy, backed by an example where adding it would have hurt the team.
- Head of Datas who pair Org Design depth with cross-functional fluency - they bring product, design and data into their decisions, not just engineering.
- A written 30/60/90 plan in week one, anchored to Data Strategy delivery milestones rather than ramp-up vanity metrics.
- Versioned, observable head of data work - measurable outputs, structured logs of decisions, and a clear rollback path on every change.
Red flags when interviewing head of datas
Every discipline has its own pattern of plausible-sounding answers that fall apart in production. For head of datas, these are the patterns that most often correlate with a six-month regret hire on the employer side.
- Defines "senior head of data" purely by years of experience, not by the scope of decisions they own.
- Lists Org Design on the CV but cannot describe a single trade-off they hit in production - all framework, no friction.
- Treats the head of data 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.
- Only ever worked on greenfield head of data projects - inheriting a messy, half-built system is a different muscle.
What to expect in the first 30 days from a Haystack head of data hire
By week one, the new head of data 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 data 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 data 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.
