Who we are

Today PRISMA connects around 20 European markets, making it the leading platform for the movement of gas around the continent. And with the Green Transition well underway, we're now striving to further integrate Europe's energy infrastructure and help secure its energy supply for decades to come. To achieve this, we hand-pick the best tech stacks to solve every challenge we face, ensuring PRISMA remains at the cutting edge of a fast-evolving industry. Learn more about our journey here.

We believe that the strength of PRISMA lies in our people, including their growth, their well-being, and their diverse perspectives. Diversity, Equity, and Inclusion are central to our mission, as detailed in our DEI Matters initiative. With more than 20 nationalities in our team, we are proud of a rich mix of backgrounds and ideas, from music lovers and gamers to philosophers and cycling enthusiasts. This diversity of thought and experience is what drives our innovation and success.

Now, we are looking for two people to join our first structured Trainee Program in Product & Platform roles. Over 18 months, you will build the skills, experience, and perspective to take on a real career in product ownership, customer success, or platform management at PRISMA.

What you'll do

This is a structured 18-month program with a designed curriculum, real deliverables, and real responsibility, earned progressively as you grow. Its centre of gravity is Product Ownership, but it is deliberately broad, preparing you for a genuine range of career paths within PRISMA.

The program runs across six phases:

• Phase 1 · Foundations: PRISMA's products, the European gas market, agile basics, and technical orientation for non-engineers;
• Phase 2 · Immersion: Embedded in Customer Success, introduction to Domain-Driven Design and Event-Driven Architecture, and your first user stories;
• Phase 3 · Practice: Backlog ownership, Event Storming co-facilitation, PMO governance basics, and cross-functional presentations;
• Phase 4 · Deepening: Full requirements lifecycle covering system vision, algorithm specification, event and data design, roadmaps, and service provider coordination;
• Phase 5 · Ownership: Leading discovery and business cases, stakeholder strategy, and AI-assisted product and platform workflows;
• Phase 6 · Graduation: Full responsibility over a product or platform scope, peer review by the other trainee, and a competency-based evaluation.

By the end of the program, you will be well-placed to step into one of the following roles:

• Product Owner: owning a product scope, partnering with engineering teams, and setting direction for what gets built and why;
• Customer Success Representative: the expert bridge between our platform and the transmission system operators, storage providers, and market participants who rely on it;
• Project or Service Manager: governing complex delivery, managing external partners, and ensuring that platform commitments turn into reliable outcomes.

You do not need to know today which of these fits you best. The program is designed to help you find out.

What we expect

We are deliberately keeping this open, because strong platform professionals come from very different starting points. What matters most is attitude and aptitude. In general, we expect you to have:

• A completed qualification in an IT-related field, whether a university degree (computer science, business informatics, economics, engineering, or similar) or a vocational qualification such as Fachinformatiker with relevant professional experience;
• A genuine interest in software and how digital products are built and operated. You do not need to write code, but you need to care about what is under the hood;
• Fluent English, written and spoken, as PRISMA is a multi-national environment and English is our working language;
• Clear, structured communication, as you will regularly be the link between engineers, customers, and business stakeholders;
• The ability and willingness to work primarily on-site in Leipzig, as the program's rotation and mentorship structure requires presence.

The following would be a strong advantage:

• Advanced German skills (B2 or above), as many of our customers, regulatory documents, and key stakeholders operate in German;
• Experience in an IT or software environment in any capacity: support, QA, development, system integration, agile team membership, internship, or working student role;
• Exposure to regulated industries, B2B platforms, or the energy and infrastructure sectors;
• Intellectual curiosity about the European energy transition and the role that digital infrastructure plays in making it happen.

What we offer

• A genuinely structured learning path with modules, milestones, mentored deliverables, and clear phase gates;
• Two trainees hired simultaneously, with pair learning, peer feedback, and a built-in professional relationship from day one;
• Direct mentorship from experienced Product Owners, engineers, customer-facing colleagues, and senior domain experts;
• A real and open career horizon: the program gives you the foundation for multiple trajectories and helps you find your fit;
• Work that matters, on real infrastructure for a continent in transition;
• A Leipzig office with 20+ nationalities, flat hierarchies, and a culture of transparency;
• Occasional home-office flexibility after the initial onboarding phase.
