An in-house QA automation engineer or an external supplier?
The decision usually looks like a question of price: how much does a full-time employee cost versus how much will a supplier charge? But this is not a comparison of two invoices. These are two different ways to introduce automation, and each has its place. Below, we explain what both options involve without pushing you towards one answer.
Common problem: an in-house person or a supplier?
Your own QA automation engineer makes sense when the work is continuous rather than occasional.
- The product will live for years and changes every day. A suite that interacts with the application every week needs clear ongoing ownership. In that situation, maintenance is not a one-time project but operational work.
- The domain is complex. Insurance, healthcare, logistics, or accounting. If it takes months to understand what the correct result actually is, it would be wasteful for that knowledge to leave with someone at the end of a short engagement.
- The team is large enough to sustain the role. The required capacity depends on the product’s size, rate of change, and suite scope; a full-time role may not make economic sense for a small or intermittent need.
- You want QA directly within the team. A person who takes part in planning and sees what is coming can highlight risks before implementation. External cooperation therefore requires well-structured communication with the product team.
The catch is what these points leave out: recruiting an experienced automation engineer can take time and also creates ongoing costs for retaining the expertise. While you search, regression testing may remain predominantly manual.
When an external supplier is worthwhile
- You need a result before recruitment can finish. While you publish the vacancy, conduct interviews, and wait for the selected candidate to complete their notice period, an external team can start on the critical part of the suite and its pipeline integration.
- The need is temporary. Building the suite’s foundations, rescuing a suite that stopped working, or covering one large feature before release. These are tasks with an end, not a reason to create a permanent position.
- You need several types of expertise. Web, mobile, API, performance testing, accessibility, and CI/CD require different experience. Depending on the scope, an external team or specialist supplier can involve people from several areas; verify which capabilities it actually covers when selecting one.
- You want to pay for a result, not a position. A fixed price for a clearly agreed scope reduces the risk of costs changing unexpectedly during delivery. With an employee, you carry the monthly cost.
One point is often underestimated in external cooperation: the handover of knowledge needs to be agreed in advance. The contract should clearly state who owns the resulting code and where it will be stored. In our usual way of working, we hand the source code over to the agreed repository together with documentation and rules for further development. We build the solution mainly on open-source tools and disclose any paid or proprietary dependencies in advance.
How to approach it: the options can be combined
This is not necessarily an either-or choice. A common model is to have an external supplier build the foundations and gradually bring maintenance in-house. The supplier prepares the framework, covers the first critical journeys, and introduces a maintainable structure. After training, and depending on their technical experience, an in-house person can add scenarios to the finished framework. The initial architecture and working rules are often a demanding part of the project; subsequent expansion still needs dedicated capacity and ongoing quality control.
The reverse also works: the in-house team continues independently and uses external help only for areas where it lacks capacity or experience.
What the right division of work gives you
A decision you can justify. Not “everything in-house” or “everything outsourced”, but a division based on what is permanent in your situation and what is temporary.
Next step
If you do not know which side you are on, contact us. We will review how you test today, how often you release, and what you expect from automation, then explain what we would keep in-house and what we would outsource in your position. If your own employee is enough, we will say so. If you first want an independent view of the entire process, that belongs in test strategy and a QA audit.
