ICT system tester

What the work can involve

ICT system testers check whether information and communication technology systems behave as expected before release or delivery. The work can include understanding requirements, preparing test plans, writing test cases, running manual or automated tests, recording defects and retesting fixes. Testers often work with developers, analysts, product owners, support teams and clients to clarify issues and help ensure systems are reliable, usable and ready for internal or external users.

Skills and specializations

Useful skills include structured test planning, clear test-case design, careful documentation, defect reporting, troubleshooting and communication with technical and non-technical colleagues. Some roles focus on functional testing, integration testing, regression testing, security testing, performance testing or test automation. Understanding requirements, release processes, data quality and system dependencies can be important, especially when several applications, suppliers or client environments are connected.

Salary context

Salary context can differ between software companies, consultancies, public-sector employers, financial services, telecom, healthcare technology and internal IT departments. Seniority, automation skills, domain knowledge, responsibility for test strategy, release-critical systems and client-facing delivery can all affect positioning. When comparing roles, it is useful to consider work location, remote expectations, on-call or release-window work, certification preferences, team size and whether the role is mostly manual testing, automation or quality leadership.

Career paths

Career paths can move toward senior tester, test lead, QA engineer, test automation specialist, release manager, requirements analyst, product owner or quality assurance manager. Some testers develop deeper technical skills in scripting, APIs, databases, cloud systems or security testing. Others build domain expertise and become strong bridges between users, clients, developers and delivery teams. The best path often depends on system type, interest in coding, communication strengths and appetite for coordination responsibility.

Good to know

System testing is often detail-oriented and collaborative. A tester may spend time reproducing unclear issues, checking logs, refining steps, asking questions about requirements and verifying that fixes do not create new defects. Job ads can use titles such as software tester, QA tester, system test engineer or test automation engineer for overlapping work. Candidates should read the tasks carefully to understand the balance between manual testing, automation, client contact, documentation and release support.
