Your first HR hire in Ireland: when and who
Reviewed by Mellow Editorial Team, HR & payroll content team
Hiring your first dedicated HR person is one of the clearest signs a business is moving from startup scrappiness to something more structured. The right time is usually when people problems are taking up more of your week than product or sales decisions — typically somewhere between 25 and 50 employees, though the trigger varies by business type.
When does HR actually become necessary?
Most founders handle people matters themselves in the early stages, which is fine. Employment contracts, onboarding, a leaver here and there — these are manageable with a decent template and some attention to detail.
The warning signs that you need dedicated HR tend to cluster around the same themes:
- You are spending more than half a day each week on people-related admin or conversations
- You have had a grievance, disciplinary issue or a WRC complaint, and you handled it without a clear process
- Headcount is growing fast enough that you are losing track of who is in probation, who is due a review, who has taken their statutory four weeks of annual leave
- You are hiring in multiple locations or adding contractors alongside employees
Ireland has a relatively dense body of employment law — the Workplace Relations Act, the Employment Equality Acts, the Organisation of Working Time Act, the Safety, Health and Welfare at Work Act, among others. The compliance burden alone justifies bringing in someone who knows it.
Generalist or specialist?
For a first hire, the answer is almost always a generalist. You do not need a specialist in learning and development or a compensation analyst at 30 people. You need someone who can handle the full employee lifecycle competently.
A good first HR hire in Ireland should be comfortable with:
- Drafting and reviewing employment contracts that comply with Irish law (including the statutory requirement to give written terms within five days of starting)
- Running a disciplinary or grievance process in line with the WRC Code of Practice
- Managing payroll inputs accurately and on time — understanding PAYE, USC and PRSI obligations even if a payroll bureau or software handles the actual submissions
- Keeping leave records straight across annual leave, sick leave, parental leave and the various other statutory entitlements
- Supporting managers on day-to-day people issues before they escalate
The CIPD qualification is the standard credential in Ireland. A CIPD-qualified HR generalist at the associate or chartered level is a reasonable benchmark for your first hire, though practical experience in an Irish employment environment often matters more than the letters after the name.
What to pay
Salaries for HR generalists in Ireland vary by experience and location. In Dublin, an experienced generalist with four to six years under their belt will typically command somewhere in the €50,000–€65,000 range. Outside Dublin, expect that to be somewhat lower. A senior HR manager with 10 or more years, including prior responsibility for building out an HR function, will be at the higher end or above.
Employer costs go beyond gross salary. PRSI at 11.15% sits on top of every euro of payroll. Add employer pension contributions — and bear in mind that from 2026, pension auto-enrolment under the My Future Fund scheme is being phased in, which will introduce mandatory employer contributions for eligible employees. Factor that into your total cost of employment calculations when budgeting for the role.
The fractional option
If 30 or 35 employees feels too early to justify a full-time hire, a fractional or part-time HR consultant is a legitimate middle ground. Some HR professionals operate on a retained basis — two or three days a week, or a set number of hours per month — which gives you access to proper expertise without a full headcount addition.
This works well for businesses that have relatively stable teams and a low volume of complex cases. If you are in a growth phase and hiring frequently, the fractional model tends to strain quickly — the HR function becomes a bottleneck when the person is only available two days a week.
Setting your first HR hire up to succeed
Bringing someone in and expecting them to fix everything immediately is a common mistake. A first HR hire needs a few things to be effective: a clear mandate from leadership, access to employment contracts and any existing policies, visibility of payroll data (or a direct relationship with whoever handles payroll), and the authority to implement processes rather than just recommend them.
It also helps to be honest about what is already in place. If your contracts are outdated, your disciplinary procedure is a single paragraph in a staff handbook last updated four years ago, or your payroll submissions to Revenue have been inconsistent, say so upfront. A competent HR hire will not be surprised — they will just need to know where to start.
