Our systems enable high-performance sensing and monitoring through advanced photonics, signal processing, and data-driven intelligence.\nWe are expanding our R&D team with an Integration Software Engineer who is passionate about quality, structured validation, and delivering robust software in complex engineering environments.\nAs 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.\nThis 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.\nKey Responsibilities\nLead software integration engineering for our underwater acoustic sensing systems, ensuring frontend and backend components, algorithms, and hardware systems work together reliably.\n\nIntegrate the algorithmic toolbox with our system backends, turning research code into maintainable, versioned and deployable software components.\n\nImplement data interfaces for our real-time sonar processing pipeline, to ingest multiple sensors (acoustic, heading, temperature, pressure, etc.) from internal and external data acquisition systems. Implement health reporting, logging and monitoring, so that the status and performance of software and system components is visible and actionable.\n\nDevelop the software control layer for our sensing systems and their hardware components, including APIs for commanding, state handling, error handling and recovery.\n\nImplement, align and verify software integrations with external partners and C2 systems, being directly involved in defining interfaces, maintaining interface specifications and running joint integration tests.\n\nTesting & debugging: Develop system-level test suites and CI/CD pipelines, diagnose communication failures, and ensure secure, reliable data transfers as the toolbox and backends evolve.\n\nAddress performance, latency and scalability of the integrated pipeline, together with algorithm and backend developers.\n\nWork hands-on with integrated software and hardware systems at our headquarters and production facility, with occasional on-site visits.\n\nReview the work of junior engineers and external development partners in depth, promote good practices for packaging, versioning and release, and share integration knowledge across the team.\n\nWhy Join Us?\nJoin one of Europe’s most promising deep-tech scale-ups.\n\nShape the future of a rapidly growing multidisciplinary R&D organization.\n\nCompetitive salary and benefits package.\n\nEnjoy regular team activities and company events.\n\nFresh team lunches provided 3 times/week.\n\nRequirements\nQualifications:\nBSc or MSc in Computer Science, Software Engineering or a related field.\n\nSignificant professional experience in software engineering, with a focus on system integration, backend or platform development.\n\nExtensive experience developing production software in Python, including packaging, testing, dependency management and writing maintainable, well-structured code.\n\nFamiliarity with systems programming in C++, or Rust, for the purpose of extending Python for more performance or hardware control.\n\nProven experience designing and implementing APIs and messaging interfaces (e.g. MQTT, WebSocket) and data serialization (e.g. protobuf).\n\nExperience with realtime data pipelines, and handling high-throughput or streaming data.\n\nExperience with Docker, CI/CD and automated testing in a Linux environment.\n\nExperience working with software that interacts with physical systems, and comfort doing hands-on integration and troubleshooting in a lab or production environment.\n\nExperience reviewing code and designs, mentoring junior engineers, and setting engineering standards.\n\nAn outcome-focused mindset, with the ability to own a problem end to end or break it down for others.\n\nAbility to work with algorithm developers and translate research code into robust, maintainable software.\n\nFlexible and proactive in taking on what needs to be addressed, and comfortable in a fast-paced scale-up environment.\n\nGood communication skills in English and the ability to coordinate with internal teams and external partners.\n\nWillingness to work primarily from our Amsterdam headquarters, as parts of the role involve classified information and physical systems.\n\nNice to Have:\nKnowledge of defense systems or defense standards (e.g. NATO STANAGs, MIL-STD), for example in naval, maritime security or surveillance systems.\n\nExperience with the scientific Python stack (e.g. NumPy, SciPy) or integrating signal processing or ML models into production systems.\n\nExperience developing software interfaces for controlling instruments or devices.\n\nExperience with other messaging or streaming frameworks (e.g. Kafka, ZeroMQ, DDS).\n\nFamiliarity with observability tooling.\n\nSecurity & Compliance:\nYou'll be working with clients in the defense and security sectors, obtaining a Certificate of No Objection issued by the AIVD (Dutch General Intelligence and Security Service) is mandatory. This means you will need to undergo a security screening.
