Solution Architect - Market Sourcing & System Planning (f/m/d)

50Hertz Transmission GmbH, part of the European Elia Group, is seeking a Solution Architect to lead the Market Sourcing and System Planning domain. The role is based in Berlin, onsite at the Berlin-Mitte office (Heidestraße 2, 10557 Berlin), and the company is actively driving the energy transition by continually shaping its IT landscape. This is a fixed-term, full-time position aimed at someone who wants a central part in delivering secure, scalable IT solutions for a high-stakes energy business.

The position starts as soon as possible and runs for two years, with a 37-hour workweek. The team is looking for someone who thrives in cross-border collaboration, interacts with specialists in the 4ÜNB environment, and can contribute to national and international initiatives within the Elia Group.

If you enjoy shaping core IT capabilities for Remedial Action and Capacity Management and want to contribute to a central business area in a company actively advancing the energy transition, this could be a strong match for you.

Shaping the IT backbone for Remedial Action and Capacity Management

You will own the target and solution architectures for the Remedial Action and Capacity Management domains across the complete lifecycle of IT solutions. You’ll translate regulatory, business and technical requirements into architectures that are secure, economical and sustainable, aligning with national and common solutions across the four German transmission operators (4ÜNB). You’ll design and advance how applications, data and integrations fit together, laying down roadmaps and standards and ensuring clean interfaces with 4ÜNB solutions and external market partners. You’ll make sure architecture governance, security, data protection and KRITIS requirements are met, while analyzing dependencies and risks and identifying improvement opportunities across multiple systems and services. You’ll advise projects and product teams on design choices and technology options, and you’ll work closely with business areas, product and service teams, IT security, infrastructure and platform teams to build a coherent, future-proof solution landscape. You’ll also represent 50Hertz in national and international architecture forums and contribute to shared standards and joint initiatives with the 4ÜNB and the Elia Group.

You’ll have a track record in developing target architectures, transformation and migration strategies, and in managing technical dependencies across multiple systems and services.

A background in IT service management and ITIL, along with building secure, stable and economical IT solutions, is important. Strong communication and facilitation skills and experience working with business areas, product and service owners, development teams, IT security, infrastructure and platform teams are essential.
