(Junior) System Test Engineer (all genders)

Defence international
Vienna FREQUENTIS AG From now on Full time
Job Introduction
Frequentis Group with headquarters in Vienna is an international supplier of communication and information systems for control centres with safety-critical tasks. Worldwide, more than 500 customers in some 150 countries with more than 45,000 workstations already trust our know-how and proven experience. 

Your mission:

As a System Test Engineer, you are part of an international team of experts, working on cutting-edge solutions that quite literally take flight: our systems are deployed directly in airport control towers as well as in Deployable Digital Towers, environments where safety, precision, and reliability are paramount.

You play a key role in ensuring that these critical infrastructures operate smoothly, from installation and acceptance testing to operations and continuous development.

If you are passionate about IT and technology, enjoy taking on challenging projects, especially in safety-critical environments, and can imagine working internationally, then you are a perfect fit for us.
Key Tasks
  • You put our systems to the test and support the team throughout specification, implementation, and acceptance—from smart standard environments to cutting‑edge “Deployable Digital Tower” solutions. This is where you help shape the technology of the future.
  • During testing, integration, and commissioning phases, you are right in the middle of the action: you actively support the team, drive processes forward, and ensure that our systems go live reliably and stably.
  • You analyze requirements in detail and present them in a clear and structured way. Based on this, you plan, design, and execute tests—both manual and automated—ensuring the high quality of our solutions.
  • You systematically get to the root of issues: with an analytical mindset, you identify causes and support troubleshooting—efficiently, solution-oriented, and sustainably.
  • You document results clearly and comprehensibly and support system acceptance with your expertise through to successful completion, both on-site and remotely.
  • With up to 10–15% international travel, you bring our high-tech solutions into operation worldwide and make innovation tangible on a global scale.
Key Qualifications
  • You have completed technical training with a focus on IT/telecommunications or possess a comparable qualification and are eager to apply your knowledge in challenging projects.
  • You have initial experience in testing—ideally in integration or system testing—demonstrate strong analytical and technical skills, and approach challenges with a structured, solution-oriented mindset.
  • Ideally, Linux and network technologies (RHEL, Layer 2/3, UDP/TCP/multicast) are familiar to you, and you enjoy combining them with your knowledge of modern IT infrastructure and COTS hardware. You have already successfully worked with tools such as JIRA, JAMA, and test automation frameworks.
  • You communicate confidently in both German and English and enjoy contributing this to collaboration with international customers.
  • A high level of initiative, sense of responsibility, and enthusiasm for global projects drive you—whether for on-site or remote installations, rollouts, or innovative system solutions.
