Test Automation Engineer

As Automation Test Engineer you design, develop and maintain automated and manual testing solutions for OneSpan hardware products, combining test automation with embedded software/firmware validation and a strong focus on end-user testing.

Working closely with the software and firmware teams, you build test strategies, test specifications, test harnesses, automation frameworks and Hardware-in-the-Loop (HIL) infrastructure.

The role is hands-on with embedded devices such as STM32-based targets, using Python automation to run repeatable functional, integration, regression, stress and reliability tests, and to investigate failures across the full software and firmware stack.

Key responsibilities

• Design, develop, execute and maintain automated test cases and frameworks so products meet functional requirements and design specifications.

• Build and maintain automated test infrastructure, including Hardware-in-the-Loop (HIL) setups, test fixtures and harnesses for embedded devices.

• Develop Python-based automation for device control, test execution, data collection, validation and reporting.

• Execute manual and automated functional, integration, regression, performance, stress, endurance and reliability tests on physical devices and software.

• Create repeatable test cases and acceptance criteria that maximise functional and system-level coverage, and help define test strategies for new features.

• Maintain automated regression suites and integrate hardware-based testing into CI/CD pipelines where appropriate.

• Investigate failures across software, firmware and test environment, drive root-cause analysis with developers and document defects clearly.

• Monitor test results for trends and recurring failures, and act as an advocate for quality throughout the development process.

• Degree in Computer Science, Computer/Electrical Engineering or equivalent practical experience, with a professional interest in embedded systems, hardware and firmware.

• 3-5 years of experience testing software, firmware or embedded systems, including physical devices in a development or laboratory environment.

• Experience developing automated tests in Python (or another object-oriented language); frameworks such as pytest, Appium or Behave are an asset.

• Experience with Hardware-in-the-Loop (HIL) or other hardware-based automated test environments is highly desirable.

• Experience with load, stress, performance, endurance and reliability testing.

• Familiarity with Git and modern software development practices.

• Strong analytical and troubleshooting skills: able to analyse logs, test results and measurements and pinpoint hardware, firmware or software causes across multiple system layers.

• Able to work independently within a multidisciplinary engineering team and deliver to schedule, with good technical writing skills and fluency in English.

• ISTQB Level 1 certification and willingness to obtain additional ISTQB certifications.

Preferred technical skills & experience

• Python automation for physical hardware and laboratory equipment.

• HIL, SIL or system-level automated testing, integrated into CI/CD pipelines.

• Agile software/hardware development environments.

Key competencies

• Automation & hands-on testing: building reliable, maintainable automated test solutions and working directly with physical devices and fixtures.

• Troubleshooting: systematically investigating failures across multiple layers of a product.

• Quality mindset: strong focus on product quality, test coverage, reliability and customer impact.

• Curiosity & collaboration: digging into how systems really work, and communicating effectively with firmware, software, QA and support teams.
