At Xomnia, data platforms are recognized as the foundational architecture for the AI revolution. As a Medior Data Platform Engineer, you will build the infrastructure that allows organizations like KLM, Enexis, and Rabobank to turn complex data into decisive actions. 

This role serves as a critical bridge between raw data and impactful decision-making, requiring a balance of deep technical knowledge and an understanding of the business logic that drives data value.

Build the systems that transform AI ambition into reality

Joining Xomnia means stepping into a community of over 20 nationalities united by a shared passion for harnessing data and AI to tackle immediate and future challenges. The Xomnia way is defined by a culture of open sharing, where curiosity is celebrated, and the courage to challenge the status quo is encouraged. 

The trajectory for a Medior engineer at Xomnia is one of deliberate growth. While initially focused on building and improving systems, you will gradually assume greater ownership of architectural decisions and technical trade-offs. This progression is supported by a platform that encourages mentorship from senior architects and provides the freedom to experiment with new technologies during dedicated internal time. 


What the journey looks like in practice

During your week, your time will be divided between our cozy Amsterdam HQ, home-office environments, and strategic visits to clients. 

Our Raamstraat office, with its uneven floors and canal-side beanbags, serves as the heart of the team's collaborative efforts, especially during Xomnia Fridays when the team gathers to design together and resolve technical blockers over some good coffee.

Some examples of the type of data engineering projects we’ve worked on in the past can be found here, at a.s.r, here, a project for DAF, and here, at Albert Heijn.


What you bring to the table

You thrive in collaborative environments and possess the desire to turn complexity into clarity. Beyond technical skill, we are seeking individuals who combine strategic thinking and immediate value, and are comfortable navigating the ambiguity inherent in high-stakes data projects. What’s expected of you:

  • Approximately 3+ years of experience in data-intensive or backend systems, with a proven track record of building reliable, production-ready solutions.
  • Confidence in Python and SQL, with a commitment to writing clean, maintainable, and well-documented code.
  • Hands-on experience with cloud data platforms (AWS, Azure, or GCP) and a solid understanding of data modeling for analytics and reporting.
  • A collaborative and proactive mindset, with the ability to communicate complex technical concepts to both technical peers and non-technical stakeholders.
  • Fluency in both English and Dutch, enabling effective partnership with a diverse range of local and international clients.
  • Experience in Infrastructure as Code (IaaC), Containerisation, or advanced Cloud knowledge is a great plus.
  • Current eligibility to work in the Netherlands.


What's in it for you?

Xomnia provides more than just a salary; it provides a comprehensive platform for professional and personal advancement. The organization believes that the best results come from individuals who are empowered to manage their own growth while enjoying the ride together.

  • A monthly salary between €4,300 – €5,400 (based on 40 hours), complemented by Stock Appreciation Rights to share in the company’s success.
  • A dedicated €5,000 annual development budget, plus access to internal training through "Learning Labs" and "Health Month" initiatives.
  • 25 vacation days to fully recharge, with the possibility to take unpaid leave or work from abroad occasionally.
  • Memorable company trips (from Berlin to Jordan and ski trips), regular boat rides through the Amsterdam canals, and a fully stocked bar and healthy lunch at the office, every day.
  • A secondary benefits package including a solid pension scheme and flexible working options.
