Automation agency vs hiring an in-house engineer, which is better?
An in-house engineer makes sense when automation is core, ongoing, and tied to the product. An agency is better for projects with a defined endpoint, multiple systems, or specialised skills you don't need full-time. A senior automation engineer in Europe costs €120-160k all-in per year; one agency engagement typically costs less than a quarter of that and ships in weeks.
The trade-off is fixed cost vs project cost, and continuity vs specialisation. A senior automation or platform engineer in London, Berlin, or Amsterdam costs €120-160k per year all-in by the time you add benefits, taxes, and equipment. They are most valuable when automation is core to the product or there's a steady stream of internal tooling work.
An agency makes sense when the work is bounded, a defined number of workflows to ship, a re-platforming, an integration build, or when the skills needed are specialised (LLM orchestration, vector search, prompt engineering at scale) and you don't have the volume to justify a full-time hire. Most agency engagements ship in weeks, on a fixed scope, and leave the source code and runbooks behind.
The pragmatic answer is often both. An agency builds the first generation of systems, instruments them, and trains an in-house operator to run them. The engineer takes ownership six to twelve months in. That avoids the trap of a six-month hiring cycle for work that pays back in eight weeks.
