Software Engineer - Frontend Autonomous Air System V&V

Who we are Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards. As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously. We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications. The role Our Autonomous Air System V&V team builds the simulation and validation environments that enable rigorous testing of autonomous air systems before they ever leave the ground. We develop Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) environments that allow engineers to integrate, test, and assure AI-driven capabilities against virtualised and representative hardware. We build software that is subject to significant and unorthodox technical constraints, must operate in a wide variety of constantly-changing environments, and has to support an ever-growing list of challenging use-cases. What we build ultimately ends up in the hands of real people in high-risk, high-stress situations – from mission planning to command and control (C2) and mission debrief – so must be both reliable and frictionless. Taken together, this brings a whole host of interesting engineering challenges across a wide variety of fields that you'll help us solve. To give some examples: Data visualization (e.g., rendering complex simulation outputs, test results, and AI behavior in human-understandable ways) Human-Autonomy Teaming (e.g., UIs for effective human oversight, control, and trust calibration) Real-time interfaces (e.g., live test execution dashboards, simulation monitoring, and streaming data displays) Complex technical UIs (e.g., making dense, multi-dimensional data accessible to engineers and operators) Design systems (e.g., building reusable component libraries that enable rapid, consistent UI development across products) Frontend performance (e.g., efficiently rendering large datasets, optimizing real-time updates, and maintaining responsiveness under load) In several of these areas, we are working near the state-of-the-art; we actively read (and sometimes implement) research papers, and often need to push even further to make theory work in practice. In others, we are applying well-known techniques to real-world situations (with real-world limitations) that have never been used in before, which requires skill, diligence, and honing a deep understanding of the underlying technologies. The day-to-day Review code contributions, proposals, and RFCs from colleagues. At Helsing we strongly believe that unblocking others takes precedence over spending more time on your own work. Own the user interface end-to-end, from early wireframes and prototypes through to production-ready code. You'll work closely with product and UX colleagues to shape how engineers interact with our tools. Propose and implement new features, capabilities, visualizations, or even full products across our stack. We encourage our engineers to look beyond their immediate team for missed opportunities, and to speak up when they identify one. Translate complex technical data into usable, intuitive interfaces. You'll turn raw simulation outputs, test results, and AI behavior data into visualizations that engineers can actually understand and act on. Establish and evolve our component library, ensuring consistency, reusability, and alignment with our visual design standards across multiple front-ends.
