Release Train Engineer

Drive Agile Excellence Across Teams and Transform How We Deliver Energy Solutions!

At Luminus, we’re driving the energy transition—balancing planet, people, and progress through innovative energy solutions and services. Our IT team delivers value for Luminus and our customers, focusing on robust, secure and sustainable technology. We’re transforming our Cloud, Data and Security capabilities to support the energy transition.

As a Release Train Engineer (RTE), you are a servant leader and agile coach for the OptiGen scrum teams. You work closely with Product Owners and Scrum Masters to help teams become high-performing, self-organizing units that consistently meet their goals. You foster collaboration across teams, manage dependencies and lead key transformation projects across Program Increments, all while embracing SAFe principles and agile best practices.

At the same time, this role goes beyond the typical scope of an RTE: about 50% of your focus lies on product management and project-follow up, ensuring alignment between delivery goals, roadmap execution and business priorities.

What you’ll do

• Support the Domain Director Optimization & Generation as you lead medium-sized transformation programs from intake to delivery.
• Co-manage the translation of the IT roadmap into actionable technology projects, ensuring you maintain alignment with delivery goals.
• Help the teams stay focused on sprint and PI objectives as you remove blockers and drive progress.
• Ensure quality standards are upheld across scrum teams as you guide them through definitions of ready and done.
• Coordinate dependencies and releases across teams and ARTs while you structure project follow-up in Jira.
• Represent the release train in the Lean Agile Centre of Excellence as you foster collaboration and agile maturity.

What you bring

• You have solid experience in Agile methodologies, preferably SAFe, and a strong background in project/program management.
• You are used to facilitate and guide agile processes across teams.
• You are skilled in using Jira and other project tracking tools to monitor team delivery.
• You understand complex IT architectures and bridge agile and waterfall ways of working. 
• You communicate clearly and confidently, using storytelling and presentations to engage stakeholders.
• You think critically and creatively to improve processes and team dynamics.
• You are fluent in English; and in Dutch or French.

Why join us

• You’ll play a key role in shaping the future of energy through digital transformation.
• You’ll work in a collaborative environment that values innovation, agility, and continuous improvement.
• You’ll grow alongside passionate and experienced professionals committed to making a real impact.
• You work and connect with your colleagues at a Luminus office or from home. Need some flexibility? Your manager is open to discuss what works.
