Buying signals for industrial automation suppliers: which plants are hiring PLC and automation engineers

Why a PLC advert is a buying signal

A plant hires a PLC programmer, an Automatisierungstechniker or a commissioning engineer for one reason: there is a line to programme, retrofit or start up. The headcount request clears before the equipment arrives, because somebody has to be there when it does. So the advert goes public while the budget is already approved and while parts of the specification are still open, which is weeks or months before a tender reaches a supplier list.

That window belongs to control-system integrators, robot and drive vendors, sensor and safety suppliers, switchgear builders and MES vendors. All of them sell into a project that a job advert has already announced. On 9 September 2026 that came to 4,255 open automation postings across 1,987 employers in five European markets, and 239 employers outside the staffing sector had three or more of those roles open at once.

Method

One source, one day, stated in full so you can re-run it.

• Source. The Adzuna job-search API, country endpoints de, at, ch, nl and pl, pulled on 9 September 2026. Nothing else is blended in.
• Queries. Seven phrases run against every one of the five countries, verbatim: SPS-Programmierer, Automatisierungstechniker, Inbetriebnahme Automatisierung, PLC programmer, automation engineer, programista PLC, automatyk. Running every phrase against every market is deliberate: it catches an English-language posting on a German site and a Polish-language posting on a Dutch one.
• Paging. 50 results per page, 20 pages maximum, so Adzuna returns at most 1,000 rows per query no matter how many matches it reports.
• Deduplication. First on the Adzuna posting id, then on employer plus title plus location, which catches a re-listed advert with a fresh id.
• Exclusions. Titles containing intern, Praktikant, Praktikum, Werkstudent or stażysta are dropped. Job boards and aggregators that republish other employers' adverts are dropped as employers, because they are not the company doing the hiring.
• Staffing. An employer is flagged as staffing when its display name matches an agency marker. Those employers stay in every total on this page. The flag sits per row in the CSV so you can cut them yourself; they account for 602 of the 4,255 postings.
• Counting. An employer is the display-name string Adzuna returns, counted once per unique posting. 89 postings carry no employer name at all and sit in the country totals but outside every employer table.

Across the five countries Adzuna reported 20,689 matches and returned 5,022 rows, and the gap is the 1,000-row ceiling. Two queries hit it. Automatisierungstechniker in Germany reported 14,230 matches and returned 1,000. automatyk in Poland reported 3,437 and returned 1,000. Germany and Poland are therefore undercounted here, by an amount this pull cannot measure. Austria, Switzerland and the Netherlands returned every row Adzuna reported, so those three are complete against the source.

One query failed. automatyk against the German market returned HTTP 503 after three attempts and contributed nothing. It is a Polish term run against a German endpoint and its yield would have been close to zero either way, so the German figures stand.

What each country lost between the raw pull and the counts on this page:

Postings and employers by country

Switzerland reads as the agency-heaviest market in the set, and one employer explains most of it: Adecco posted 33 of the 207 Swiss automation adverts. Germany runs at 21.2% staffing on a much larger base, mostly through engineering-services firms placing SPS programmers on contract. The Netherlands looks almost agency-free at 3.1%, which is an artefact of the name-based flag rather than a fact about the Dutch market: several Dutch secondment firms carry no agency word in their name.

The 15 largest automation employers in each market

Ranked by open automation postings on the pull date. The location column is the city Adzuna returned most often for that employer, which for a multi-site company is the busiest site rather than the head office. Employer names are printed as Adzuna returned them, so a company that lists under two spellings appears twice.

Plants, integrators and staffing agencies

The commercial question is who is behind each advert. A keyword pass over the employer name splits the 1,987 employers three ways.

Read the limits before you use it. The pass matches words in the company name and does nothing else. No register lookup, no website check, no industry code. A plant whose name says nothing about automation lands in "everything else" along with genuine end users, so that bucket is a residual rather than a verified list: BMW Group, Mercedes-Benz AG, ArcelorMittal, Nestle and Lonza all sit there. The reverse error is louder. In the Netherlands, 253 of the 259 postings in the integrator bucket come from one employer, Synsel Techniek, whose name carries "Techniek" but which places technical staff rather than building lines. A single row moves a national figure. Verify each account before you write to it.

An integrator in this list is two different signals. If you are a control-system integrator, a competitor advertising for three PLC programmers has won work you did not, and the useful move is to find out which plant. If you sell components, robots, drives, sensors, safety, switchgear or MES, the same row is a customer: an integrator staffing up has a live project and is still choosing what goes into the panel. The row does not change. Which of the two you are decides how you read it.

Other automation signals worth combining

Hiring dates a project. It does not tell you how big it is or what it needs. Three public signals pair with it well.

• New plant and capacity announcements. A press release names the site, the investment and the start date. Cross it against automation adverts at the same postcode and you have both the size of the project and its stage.
• Commissioning and qualification hiring in regulated plants. Pharmaceutical and food sites advertise commissioning and qualification engineers on a fixed schedule tied to the build, which makes the advert a date rather than a guess. The same method applied to German pharmaceutical sites is set out in German pharma sites hiring commissioning engineers.
• Energy-efficiency and retrofit programmes. A subsidy award or an announced efficiency target usually means drives, metering and control upgrades on an existing line, which is a different sale from a greenfield build and reaches a different buyer inside the plant.

Before any of that, size the market you are actually selling into. Our German-language guide to Zielmarkt- und TAM-Analyse covers how to bound a target market before building a list, and outbound for manufacturing covers what to do with the accounts once you have them.

Who to write to, and when

The person who placed the advert sits in HR and will not buy anything from you. In German-speaking plants the four people who decide carry the titles Instandhaltungsleiter, Automatisierungsleiter, Werksleiter and Projektleitung. Elsewhere they are the maintenance manager, the automation or controls lead, the plant manager and the project engineer. Which one you open with follows from the advert itself.

• Commissioning or Inbetriebnahme in the title. The line is nearly built. Panel and component choices are made or close to it, so lead with service, spares, training and support, and write to the Instandhaltungsleiter.
• PLC or SPS programmer for a named new line. The specification is open. Write to the Automatisierungsleiter or the project engineer, about the control platform, safety architecture or the drive package.
• Maintenance technician with an automation profile. This is an existing plant under load. Retrofit, obsolescence and spares, addressed to the Instandhaltungsleiter or the Werksleiter.
• Three or more automation roles at one site. Something large is happening. Go to the Werksleiter, and reference the site rather than the advert.

Timing matters more than volume here. An automation advert stays live for weeks, and the decisions that follow it run for months, so a first message inside four to six weeks of the posting date lands while the project is still open. Mention what you noticed in one sentence and move on. A paragraph reciting how many adverts a plant has posted and since when reads as surveillance, and the reply rate shows it.

What this dataset is not

It is one aggregator on one day. Adzuna does not mirror every national job board, and it does not see a vacancy that only ever appears on a company careers page. Two queries hit the 1,000-row ceiling, so the German and Polish figures are floors rather than counts. The staffing and integrator flags read company names and nothing else. There is no trend line here, because a single snapshot cannot carry one.

Use it to build a target list and to date a project. Do not cite it as a labour-market statistic.
