Test Engineer – Embedded Systems / HIL (Defence & Security)

We are looking for Test Engineers at Mid and Senior level to join the testing team on a project developing embedded systems for the defence domain. Testing on the project is based primarily on Hardware-in-the-Loop (HIL) environments, where the software is verified on real hardware against simulated operating conditions. The project applies demanding industry and NATO standards including STANAG. The work is onsite in Wrocław on a full-time employment contract.

• Experience with configuring and maintaining HIL test environments
• Ability to design test cases using boundary value analysis, equivalence partitioning, and decision tables
• Experience developing and maintaining automated tests in Python
• Ability to read and understand C/C++ code for system behavior analysis
• Experience working with lab equipment such as oscilloscopes, logic analysers, and debuggers
• Ability to create clear defect and test reports
• Collaboration skills with engineering teams and stakeholders in English
• Support for projects requiring compliance with NATO (STANAG) standards

Nice to have:

• Experience with SIL (Software-in-the-Loop) environments
• Knowledge of communication protocols: UART, SPI, I2C, CAN
• Experience with serial and TCP interfaces
• Experience with pytest, Robot Framework, or similar test automation frameworks
• Experience integrating HIL tests into CI/CD pipelines
• Experience working in V-model projects
• Experience in regulated environments
• Experience in the defence or security sector
• Knowledge of NATO standards, including STANAG
• ISTQB Foundation Level certification

• Configure and maintain HIL (Hardware-in-the-Loop) test environments
• Execute HIL tests and analyse test results
• Design test cases using techniques such as boundary value analysis, equivalence partitioning and decision tables
• Analyse requirements for testability and translate them into test cases
• Develop and maintain automated tests in Python
• Read and understand C/C++ code to analyse system behaviour
• Work with lab equipment such as oscilloscopes, logic analysers and debuggers
• Create clear defect reports and test reports
• Collaborate with engineering teams and stakeholders in English
• Support projects requiring compliance with NATO (STANAG) standards
• Participate in the security clearance process when required
• Work on-site from the Wrocław office

Additionally for Senior level:

• Design and develop HIL test setups
• Build and enhance automated test frameworks
• Plan and execute advanced HIL testing scenarios, including fault injection and robustness testing
• Independently plan testing activities and estimate testing effort
• Mentor junior testers and support team development
• Review test cases and automated test code
• Contribute to testing strategy and process improvements

Work on-site at the Wrocław office is required. Participation in the security clearance process may be required.
