Profile – Senior SCADA Software Engineer

Context and objective

Join a Realtime Industrial Solutions team working on a business-critical SCADA system operating 24/7 to keep a power perimeter balanced across Belgium, France, Germany, and the Netherlands, while supporting the transition to zero-carbon energy. The team develops tools for the real-time control of power plants, the integration of flexibility assets, and compliance with European grid codes.

The tools are mainly used to:
- Monitor production assets and available capacities from power plants
- Exchange information between TSOs and the real-time SCADA system (Supervisory Control And Data Acquisition)
- Calculate real-time setpoints to send to power plants in order to keep the power perimeter balanced, based on production plans, real-time acquisition, and other inputs such as FCR, aFRR, and mFRR
- Support similar balancing mechanisms across several European countries

Technical environment

- Main application: Hitachi ABB MicroSCADA SYS600 version X / Hitachi Energy MicroSCADA X
- Backend language within MicroSCADA: SCIL (Supervisory Control Implementation Language)
- Frontend: web-based, using proprietary frontend capabilities based on HTML, CSS, JavaScript, and TypeScript

Main responsibilities

- Develop and maintain the SCADA X application used to keep the power perimeter in balance
- Work on both frontend and backend development using SCIL, HTML5, CSS, JavaScript, and TypeScript
- Apply architectural design principles to build scalable and robust solutions
- Apply software craftsmanship principles such as SOLID, DRY, KISS, and YAGNI to produce clean, maintainable, and resilient code

- Contribute to on-call support after onboarding to ensure system availability and grid stability in a 24/7 business-critical environment

Requested profile

- Master’s degree with a specialization in IT and/or electrical engineering, such as software, electronics, or electromechanics
- At least 3 years of relevant experience
- Strong industrial mindset combined with a high level of software engineering, including architecture and design patterns
- Understanding of the basics of electricity production and grid transport
- Proactive and structured approach, with attention to resilient solutions supporting 24/7 operations
- Ability to react quickly to incidents, provide quick fixes when necessary, and implement sustainable corrections afterward
- Motivation to work in a team responsible for real-time activities
- Team player able to interact with peers, analysts, architects, business representatives, and other teams

- Awareness of cybersecurity principles in industrial control systems (ICS) and operational technology (OT) environments
- Compliance context includes NIS 2 regulation
- The team will support ramp-up on the specific environment during the first months
