- Onboard assets and pools by creating and applying templates, import mechanisms, visualisations, signal extensions and operational diagnostics for a high-volume asset landscape.
- Configure and verify data point handling for measurements, setpoints, commands and alarms, including quality status, plausibility checks, watchdogs, sign conventions and communication logging.
- Deploy and operate SCADA services across cloud and on-premises environments, implement network segmentation and redundancy, and maintain monitoring, CI/CD, infrastructure-as-code and ISMS-aligned operational controls.
- Develop, test, document and release technical solutions in close cooperation with business stakeholders, vendors, Enterprise Architecture, developers and operations, and follow agreed agile delivery and change processes.
Job requirements and experience

- Hands-on knowledge of industrial communication and integration patterns, ideally including IEC 60870-5-104, ICCP, Modbus, RTU connectivity, TSO interfaces and asset communication protocols.
- Experience with system design for complex, highly available services, including redundancy, monitoring, logging, incident/problem management and operational readiness for 24/7 support.
- Practical knowledge of software development using programming languages such as C#/.NET, Angular and scripting languages such as KornShell and PowerShell, with the ability to create maintainable automation, integration components and operational tools.
- Experience with modern AI-assisted development workflows to accelerate requirements refinement, code generation, refactoring, debugging, test creation and technical documentation, while retaining human ownership of architecture, security, code review and production quality.
- Good working knowledge of cloud and infrastructure engineering, preferably AWS, container platforms, Terraform or CloudFormation, Azure DevOps and CI/CD practices.
- Ability to collaborate with internal and external suppliers, challenge solution designs constructively, document decisions and communicate complex topics clearly to technical and non-technical audiences.
- Fluent English and German skills, with the confidence to facilitate workshops, requirements reviews, show-and-tells and cross-functional alignment sessions.
Advantageous, but not essential
