Cegeka is looking for a Senior Platform Developer to help build a team for one of our clients, focusing on modernizing the application landscape that supports the energy sector.

  • Take ownership in the foundation phase: develop technical analyses and proof-of-concepts that shape tomorrow’s infrastructure.
  • Co-build a cloud-native platform that’s scalable, secure, and easy to manage.
  • Strategically guide the containerization and migration of applications to AKS/ACA — you bring both vision and execution.
  • Select and implement the right SDLC tools to streamline development processes.
  • Collaborate closely with development and infrastructure teams to build a future-proof platform we can all be proud of.
  • You’ll have room to truly think, design, and build — not just execute.
  • You’ll work with cutting-edge technologies that are reshaping the energy industry.
  • You’ll be part of an ambitious, multidisciplinary team driven by innovation.

What you need to succeed:

  • You bring solid experience with Azure and .NET Core, and know how to apply them effectively.
  • Containerization? You speak the language of AKS, ACA, and Docker.
  • You’re familiar with modern Cloud Native ecosystems: service mesh, GitOps, and CI/CD are part of your toolkit.
  • Experience with application modernization or replatforming? That’s a strong asset.
  • You’re a proactive, constructive team player who isn’t afraid to challenge and build.
  • You know your way around SDLC pipelines and have experience setting them up — a definite plus.
  • Agile environments energize you — you thrive on teamwork, feedback, and iteration.
  • You always value quality over quantity.
  • And you’re fluent in Dutch — both spoken and written

What are we offering:

  • We ask a lot from you in terms of talent, but fortunately, you get a lot in return! Competencies and character are essential to us, alongside experience and ambitions. Cegeka continuously invests in talent management to ensure that all employees can realize their potential.
  • You will be starting at a Top Employer!
  • We apply a fair compensation framework, where employees are rewarded based on their role, experience, and performance—regardless of gender or other non-work-related characteristics. Benefits include an electric car with a charging card or a mobility budget, meal vouchers, eco vouchers, an attractive group and hospitalization insurance, a mobile subscription, a fixed expense allowance, a powerful laptop, and the possibility to personalize your salary package through our Flex Reward Plan.
  • Flexible working hours and an excellent work-life balance.
  • A top team, where new ideas and initiatives are always welcome! Expect team events, happy hours, and legendary company parties.
  • Tailored guidance: Throughout your career, our people managers will support you. You will have a point of contact, a personal coach, and a sparring partner.
  • Continuous learning: Through innovation centers, reading groups, knowledge-sharing meetings, hackathons, participation in conferences, and external training, we prioritize learning and development.
  • Opportunities for growth: Depending on your interests and initiatives, Cegeka offers various horizontal and vertical career paths.
  • Hybrid working: You will work from a Cegeka office near you (Hasselt, Leuven, Antwerp, Ghent), at our client in Brussels, combined with working from home.
