The short answer
When filling a service engineer vacancy, start by making the work area, the installations, the services, and the terms concrete. Distinguish required certifications from skills that can be developed on the job. Then combine targeted reach with a brief first conversation and a technically substantive interview.
Start with the work, not a generic job title
'Service engineer' can mean someone who independently resolves breakdowns at client sites, carries out preventive maintenance, or works in a team on larger installations. A refrigeration engineer needs different experience from someone in lift technology or security systems. Be clear about which equipment, breakdowns, and clients the role involves.
Describe what a working day actually involves. Does the engineer leave from home or from the workshop? How is the schedule put together? How much administration comes with the role? This is exactly the information that helps a candidate weigh up whether to make the move.
Discuss on-call duties and travel distances upfront
A candidate can be a strong technical fit and still drop out over on-call requirements or the work area. Put these points in the vacancy description and return to them in the first conversation. Don't just write 'flexible deployment' – explain what you mean by it.
- How often do evening, night, or weekend shifts occur?
- Which region does the engineer cover, and how are journeys arranged?
- What support is available when a fault is unfamiliar?
- What terms and allowances apply to this kind of deployment?
Have the responsible line manager confirm these answers. An attractive story that doesn't match the actual roster will only lead to disappointment later.
Use role-specific questions in the first conversation
Start, for example, with: 'What type of installations are you working on at the moment?' Then ask about the tasks the person carries out independently and for an example of a fault they've resolved. For certifications, note what the person holds and what this specific role requires. Don't assume a certificate mentioned in passing is valid or sufficient – verify that in a follow-up.

Identify where the recruitment process stalls
Few responses may point to limited reach, an unclear proposition, or a small matching audience. A high volume of unsuitable responses calls instead for clearer criteria and sharper campaign content. Candidates who disappear after first contact warrant a closer look at follow-up, terms, and process.
Keep these causes separate. Don't automatically raise the advertising budget when conversations are stalling because candidates don't want the roster. For every change you make, record what you're trying to improve: more relevant responses, more appointments, or less drop-off.

Frequently asked questions
How do you find a breakdown engineer who is willing to work on-call shifts?
Make the roster, the frequency, the work area, and the allowances clear upfront. Ask explicitly whether the candidate is willing and able to commit to that kind of deployment. Technical experience alone tells you nothing about it.
Do all required certifications need to be in place from the start?
Distinguish between what is required from day one and what can demonstrably be obtained through training. Have the role requirements reviewed by someone who knows the work and the applicable standards.
