Job description

We are looking for highly qualified and motivated professionals like you. If you think you have what it takes to keep Septentrio firmly in Pole Position, get in touch.

We need you for the position of a Test Engineer – GNSS Products.

The Job

As a Test Engineer, you help ensure the quality, reliability and performance of Septentrio’s high-precision GNSS products. You play an important role in the Verification and Validation (V&V) process, testing products throughout development and on existing platforms to identify defects and prevent regressions.

You combine hands-on testing with test automation, data analysis and technical reporting. Working closely with software developers and fellow test engineers, you investigate anomalies, follow up on corrective actions and help make our products more robust and reliable.

Your Mission

Test Design & Execution

• Design, execute and document functional and technical tests based on product requirements.
• Plan and perform laboratory and field test campaigns, including exploratory testing to uncover issues that planned tests may not reveal.
• Test all aspects from a receiver, from individual features during development to complete product systems.

Test Automation & Data Analysis

• Develop scripts and tools, primarily using Python, to automate test execution, data processing, anomaly detection and reporting.
• Analyze and visualize test results, identify unexpected behavior and investigate potential defects.
• Monitor product performance and verify the stability of new developments and existing products.
• Document test procedures, executions, findings and results in clear, structured technical reports.
• Report defects, help identify their root causes and follow up on firmware adaptations and corrective actions.
• Work closely with developers, product stakeholders and fellow test engineers to support product improvements and prevent regressions.

Your Qualifications

Education & Experience

• Bachelor’s or Master’s degree in Computer, Electrical, Industrial or Geomatics Engineering, Physics, or an equivalent technical field.
• Experience with Python, MATLAB and/or C for test automation, data analysis or technical tooling. Strong Python skills are particularly valuable.
• Initial experience in software, hardware or system testing is an advantage.
• Strong analytical and investigative skills, with the ability to identify anomalies, interpret test results and investigate unexpected behavior.
• A critical and curious mindset, with the motivation to uncover defects and help improve product quality.
• A diligent, organized and hands-on approach to planning tests, executing them carefully and maintaining accurate documentation.
• Creativity and initiative in designing tests that challenge products beyond expected use cases.
• Clear communication skills and the ability to collaborate constructively with developers and other team members.
• Excellent written and spoken English, particularly for technical documentation and reporting.

The following are considered a plus:

• General knowledge of GPS/GNSS principles.
• Experience with signal generators, oscilloscopes or other electronic laboratory equipment.
