Segment: Building-technology service (TGA)

The contract states a response time.
The rota has been short for months.

Your own recruiting system for building-technology service technicians, plant mechanics, mechatronics engineers and controls and building automation staff. Built inside your company, yours afterwards – first application within 72 hours.

No obligation – no lock-in contract

A building-technology service company does not only compete for its technicians with the firm two streets away. It competes with in-house industrial maintenance, which offers fixed shifts and a single plant, and with the operators whose properties it looks after – office buildings, data centres, universities, production sites. In every one of those cases the same person touches the same equipment. What differs is the driving, the call-out duty and the rota. Run a job advert in that line-up and you are up against competitors, one of whom sees your technician every week.

The role itself has also shifted. Non-residential buildings above a certain plant rating are now required to have building automation that records consumption continuously, analyses it and flags efficiency losses; the threshold has come down, and there is a retrofit period for existing buildings. Retrofit, and the energy inspection of the air conditioning system falls away – skip it, and the inspection keeps coming round. Either way it ends with the same people, alongside the recurring hygiene inspection of ventilation systems under VDI 6022, drinking water testing and the inspection of electrical installations under DGUV Regulation 3. Customers now buy records and evaluations, not just the work at the plant. That moves the person you are looking for towards controls and building automation – a profile industry is chasing at the same time.

Two things follow for hiring. The approach has to reach the people who are not currently looking. And the role profile has to answer the points a service technician actually decides on: fixed site or region, on-call duty, range of systems, vehicle, who pays for which qualification. Neither is a campaign, both are a path built once: role profile, your own careers page, channel, response rhythm, pre-selection, handover. We build it inside your company and leave it there. No fee per head, no standing contract – the next role you launch yourself.

THE RESPONSE RHYTHM

One application. Answered the same day.

A technician applies in the evening after their shift – and usually not only to you. Whoever answers first gets the interview. That is not a service promise, it is the selection mechanism of this market.

First application within 72 hours.

Then a fixed rhythm: every application answered the same day – even when the service manager is at a customer site or on holiday. The process and the templates belong to your company from day one.

  1. Mr Krüger

    Good evening, I saw your field service technician role. How large is the travel radius?

  2. Blacklyne

    Good evening! Around 180 km, you sleep at home. Overnight stays about twice a month, company vehicle provided. Which controls have you worked on most recently?

  3. Mr Krüger

    Siemens 840D and Heidenhain, seven years of CNC service. I am used to on-call duty.

  4. Blacklyne

    That fits. Our service manager has Thursday 16:30 open – shall I book it for you?

WHERE IT HURTS

What keeps your roles open.

The bottlenecks in this segment – and why they rarely sit in the market.

The operator whose building you service is bidding for the same person

Your technician drives to the same building week after week. He knows the plant, the customer’s own technical staff know him – and at some point the question comes up whether he would rather join the operator directly. One building instead of a whole territory, no driving, the same equipment. No job advert answers that, because the person who would replace him is not looking either: according to the EY job study 2025, a third of employees are open to an offer without actively searching.

Site technician and rover run under the same title

Fixed sites with keys, plant knowledge and one contact on the operator’s side are something quite different from covering half a region as a rover. One applicant wants precisely the first, the other precisely the second. In the advert both are called building-technology service technician. If you do not say which model you are offering, you get applications from the wrong people and rejections from the right ones.

The certificates are in the advert, the route to them is not

Certification under the German chemicals climate protection ordinance for work on refrigeration systems, VDI 6022 training for ventilation systems, the operator’s switching authorisation, qualification to inspect electrical installations under DGUV Regulation 3, plus drinking water hygiene. Almost no applicant brings all of it. Demand everything without saying which qualification the company pays for, and by when, and you screen out the people who would have had all of it soon enough. That information takes barely any room and is almost never there.

On-call decides it, and nobody puts a number on it

Call-out duty is not an add-on in this business, it is the reason the customer holds the contract. For the applicant, though, what decides is not the word on-call but the rota, the pay for it, and whether he is free to choose where he waits or has to wait where the employer says – two different things under working time law, and rather more than that in a family calendar. Leave it open and you lose the acceptance in the final conversation, after paying for the whole process.

THE NUMBERS

6 percent are searching. a third would be open to an offer.

According to the EY job study 2025, a quarter of employees are actively looking and another third are open to an offer without searching. A job ad addresses the first 6 percent. The rest are reachable, just not where you advertise.

Every application is answered the same day.

WHAT CHANGES

Here is what changes for you.

What ends

  • Recruiter fee per head
  • Open-ended retainer
  • Staffing mark-up
  • Accounts and applicant data with a provider

The channel runs on your accounts

Delivery is regional, to the people who are not searching who are open to a move without searching – reached where a service technician looks between two sites, not where vacancies are posted. The accounts, the territory split and the knowledge of what pulled in your catchment area are in your name and stay there from day one.

The role profile comes out of the rota, not the org chart

Site-based or roving, territory radius, on-call rota and the pay for it, range of systems, vehicle, documentation load, and which certificates the company funds: those are the details a service technician judges a working week by. We take them from your scheduling and put them at the top of the advert instead of explaining them later in an interview.

The rhythm does not hang on the site manager

First application within 72 hours. So that the reply afterwards does not depend on the call-out load, responsibility is written into the system: who answers an application while the site manager is stuck on a breakdown is settled before the first one arrives. We guarantee the hire, not the number of applications – if a committed role stays open, we keep working at no further cost.

After the handover the system is yours

The applicant who did not fit this site is still on your list when the next contract comes – not on an agency’s. Careers page, ad accounts, questionnaire, message templates, applicant data and everything documented in writing stay in your house alongside that list.

HOW IT WORKS

4 steps.
Live from day one.

First we check whether the role can be filled in your region. Then it goes out – advert, application route and campaign from us, under your name. First applications within 72 hours.

  1. 15 minutes

    Feasibility check

    Can the role be filled in your region, and is your area still open? We put in writing what “the right fit” means technically. We decline roles that cannot be filled – even when that means one engagement less.

  2. your effort: one approval

    We launch it

    Role profile with travel radius and on-call, careers page on your domain, a 90-second application path, campaign in your region. We build it and switch it live – you approve it once. Every account runs under your name.

  3. first within 72 h

    Applications

    Then a fixed rhythm: every application answered the same day, pre-screened on your service manager’s criteria. You run interviews instead of sorting. If a committed role stays open, we keep working – at no further cost.

  4. next role: one click

    It stays live

    Accounts, audiences, templates and applicant data keep running under your name – live, not a kit to learn. The next role takes minutes: type the title, tick the box, live. If you would rather hand it back to us, you can – but you do not have to.

Questions

Honest answers.

  1. 01 We are hiring for several sites in different regions. Does that need several systems?
    No. It is built once and delivered per territory – sites differ in driving, rota and range of systems, and that is exactly what then goes into the profile for each territory. What we do not do: work for two companies in the same catchment area competing for the same technicians. If your region is taken, we say so in the first call.
  2. 02 What does the system not do?
    It makes your offer visible, it does not make it better. If your on-call duty pays less than a competitor’s in the same region, the system wins you the application and loses it at the offer. When we see that, we say so in the first call – even when it means we do not take the role. What happens after the hire is decided by your company, not by the system.
  3. 03 Is there a price on the website?
    No, deliberately. What the build costs depends on the number of roles and territories. We settle that in the first call against your numbers.
  4. 04 Who runs the system from day one?
    We do – until the role is filled. After that everything stays live under your name and nobody on your side needs training. The next role takes minutes: type the title, tick the box, live.
Waiting list

One company per specialisation and area. Every slot is currently taken.

Put your name down. As soon as a slot opens in your area we will come back to you – with an assessment, not a pitch.

What happens next

  1. You leave a postcode and a website. That is all we need to place your catchment area.
  2. We come back as soon as we can – and we decline if your area is taken or the role cannot be filled. Honestly, before you lose time.
  3. If it fits, we run your area together: how many suitable technicians work within range, and what the build would cost you – including when we advise against it.

A systems builder, not an agency

The last time you pay anyone for recruiting as a service.

Blacklyne is not a recruiter, not a retainer agency and not a staffing firm. We build the hiring system once inside your company and hand it over with accounts, templates and everything documented in writing. From handover on you hire on your own – no fee per head, no monthly retainer, and no us.

What ends at handover

  • Recruiter fee, 15–25 % of annual salary – per head, every time
  • Retainer: monthly, open-ended, paying for effort rather than outcome
  • Staffing mark-up, cost factor 1.5–2.0
  • Dependency: accounts, audiences and applicant data sitting with a provider

What stays – inside your company

  • A careers page on your own domain, source code and access included
  • Ad accounts, audiences and creatives running on your company
  • Applicant data, screening questions and scoring logic
  • Operating manual and training – you launch the next role alone

Your ad budget keeps running through your own accounts, paid straight to the platform. Nothing flows to us from day one – that is the difference, not the campaign.
