About the role Xirgo Technologies is recruiting a Senior Quality Assurance Engineer to join us in creating the next generation of Video Telematics products and solutions. As a Senior QA Engineer in Video Telematics, you will play a pivotal role in ensuring the integrity and performance of complex systems through rigorous verification and validation processes. You'll collaborate with cross-functional teams—including hardware, firmware, and systems engineers—to develop and execute test plans, identify issues, and ensure system requirements are met. Developing automation for the test environment will be a key requirement for this role, se eking to maximize efficiency and repeatability. This position demands a strong analytical mindset, attention to detail, and a solid foundation in engineering principles to help deliver high-quality, reliable systems. Location Requirement: This role requires the successful candidate to work from the Belfast office. Hybrid working will be available where work requirement allow. Remote or fully remote arrangements are not available for this position. Right to Work: Applicants must have the legal right to work in the United Kingdom at the time of application. We are unable to offer sponsorship for this role. What you'll do Test Planning & Design Think automation first while designing, developing, and executing test plans and test cases for Video Telematics products and embedded systems. Plan and execute verification of features broken down into components for releases. Create and maintain documentation and perform testing across multiple devices, platforms, and browsers. Take full ownership of all QA artifacts and end-to-end testing Test Execution Perform manual and automated testing of firmware features, including ADAS, DMS, over-the-air updates, location tracking (GNSS & Wi-Fi), power management, and protocol implementation. Execute regression and performance tests to validate system robustness (e.g., ADAS, DMS, A/V recording, live streaming, vehicle telematics). Perform functional, stress, and performance tests on multiple levels within the system, including vehicle software simulation, hardware-in-the-loop automation, and in-vehicle testing. Tooling & Automation Contribute to and maintain test automation frameworks in Python or equivalent languages. Contribute to design, implement, and maintain automated test frameworks for embedded systems. Support in maintaining existing tooling, automation, and simulation code. Develop test equipment, algorithms, and methodologies to validate designs and provide feedback for design iterations. Debugging & Issue Management Use tools like Wireshark, Drewlinq, serial loggers, oscilloscopes, and power analyzers to verify data flow and system stability. Analyze logs and telemetry data to troubleshoot issues across firmware and cloud layers. Document bugs clearly in issue tracking systems (e.g., JIRA) and support developers with reproducible steps and logged evidence. Collaboration & Continuous Improvement Proactively identify execution gaps and drive process improvements. Investigate and support resolution of customer-facing issues and collaborate with leads to retrospectively analyze root causes Experience / Qualifications Bachelor's degree in Computer Science, Electronic and Systems Engineering, or a related field—or equivalent relevant work experience. 2 years of experience in a QA or Systems Engineering role, ideally within IoT or embedded systems. Experience testing embedded systems. Strong knowledge of QA methodologies, testing types, and best practices. Experience in both manual testing and automation. Strong debugging and analytical skills with the ability to understand hardware/software interactions. Excellent communication, collaboration, and organizational skills. Ability to work in a fast-paced environment and manage multiple competing priorities. High ethical standards and accountability for achieving goals and delivering quality Desirable Criteria Experience with Python test automation or frameworks. Proficiency with Testrail, Postman, Wireshark, and other data capture tools. Experience testing vehicle/video telematics, power optimization, or environmental robustness.
