Software Test Engineer
We are looking for a hands-on Software Test Engineer to ensure the quality and reliability of software solutions used in real-world sensing and data processing systems. Optics11 is a deep-tech company developing advanced fiber-optic sensing technologies for challenging environments and applications in energy and underwater security. Our systems enable high-performance sensing and monitoring through advanced photonics, signal processing, and data-driven intelligence. We are expanding our R&D team with a Software Test Engineer who is passionate about quality, structured validation, and delivering robust software in complex engineering environments. As a Software Test Engineer, you will be responsible for defining and executing practical software tests to validate software components (including algorithms, cloud back-end, and user interfaces) that process sensor signals generated by fiber-optic sensing systems. You will work closely with data scientists, signal processing specialists, back-end developers, and software architects to ensure that products meet functional and non-functional requirements. This role requires a hands-on professional with a proactive mindset, a structured approach to software testing, strong attention to detail, and the ability to understand complex technical systems and translate requirements into effective test strategies. Key Responsibilities Perform functional, integration, regression, system, and end-to-end testing across edge devices, cloud services, APIs, databases, and graphical user interfaces. Define test strategies, test plans, test cases, acceptance criteria, and automated test scripts for an edge and cloud software platforms. Identify, document, and track software defects, ensuring clear reproduction steps and proper follow-up. Collaborate with product owners, developers and engineers to understand system requirements and ensure test coverage. Contribute to the development and maintenance of automated test frameworks and pipelines. Test edge–cloud behaviour under interrupted connectivity, delayed or duplicated messages, device restarts, software updates, and synchronization failures. Validate software performance, reliability, and stability under different operating conditions. Support testing of software running on edge hardware, including hardware–software integration in laboratory and field environments. Analyse test results and provide clear, actionable feedback to development teams. Ensure traceability between requirements, test cases, and test results. Integrate automated tests into G...
