The opportunity

We are embarking on a transformation journey to shift from delivering projects only to building modern, well-defined product-based systems. Our goal is to grow our cross‑functional team, creating a dynamic environment where novel ideas and collaboration thrive. In this role, you'll help create cutting‑edge solutions for platforms that integrate IT and OT at HVDC. These platforms are the foundation our global project teams rely on. Your main focus will be developing secure OT and HMI application components where Human‑Machine Interfaces (HMIs), Gateway Stations (GWS), and communication with control systems reside. With your strong development mindset and understanding of secure design principles, you will help design and implement OT and HMI application components that can serve as reusable platform building blocks while still meeting project‑specific requirements. These components are essential for optimizing project effort and are mandatory for delivering the required functionality to our customers with high quality and long‑term maintainability. You'll document your solutions and support testing activities to ensure project teams are equipped with the correct and secure implementations when delivering to customers. Working at the intersection of IT and OT, you'll tackle real challenges, build scalable and secure application components, and influence how we innovate and collaborate. If you're motivated to think beyond individual implementations, create smart and secure OT application solutions, and make a meaningful impact across the organization, this opportunity is for you.
