DevOps / Security Engineer

Securing and scaling the digital infrastructure for plant resilience research. CropXR is a Dutch public-private research initiative focused on climate-resilient agriculture. Within CropXR, the Resilience Hub provides a central digital infrastructure for integrating and analysing experimental, phenotypic, and genomic, data from a broad range of academic and industrial research partners. The Resilience Hub is built at TU Delft in collaboration with SURF, the Dutch national research and education network, which provides cloud infrastructure, storage, and associated digital services for the academic and research community. To strengthen the technical foundation of the Resilience Hub, we are looking for a DevOps / Security Engineer who will help design, operate, and secure the platform infrastructure. The role focuses on ensuring that the system is reliable, scalable, and secure, while aligning with best practices for research data platforms.

This position is part of the engineering team supporting CropXR's data infrastructure.

You will:

• Design, implement, and maintain the infrastructure supporting the Resilience Hub, primarily using services provided locally and through SURF.
• Develop and improve CI/CD pipelines for reliable deployment of services.
• Ensure security-by-design across infrastructure and services.
• Manage and improve identity and access management (IAM), authentication, and authorization systems.
• Work with SURF-provided services for compute, storage, networking, and platform integration, ensuring optimal use of the available research infrastructure.
• Monitor system performance, reliability, and security, and implement alerting and incident response procedures.
• Contribute to architectural decisions around scalability, cost efficiency, and maintainability.

Do you have a Bachelor's degree?, We are looking for candidates with:

• Experience in DevOps, platform engineering, or infrastructure engineering roles.
• Strong understanding of cloud-native architectures and containerized systems.
• Hands-on experience with tools such as Kubernetes, container, and CI/CD systems.
• Security experience in Python environments
• Experience implementing or maintaining security controls, including network security, secrets management, and access control.
• Familiarity with identity and access management (IAM) systems and secure service-to-service communication.
• Solid programming or scripting skills.
• Experience with monitoring, logging, and observability systems.

We would particularly value experience with:

• Experience working with or in collaboration with SURF cloud and other services.
• Security practices in research, academic, or data-intensive environments.
• Operating systems handling sensitive or large-scale scientific data.
• Infrastructure supporting data platforms, scientific computing, or ML workflows.
• Incident response, vulnerability management, and security auditing.
• Working in interdisciplinary environments involving both researchers and engineers.

Applicants who do not meet every requirement but have relevant infrastructure and security engineering experience are encouraged to apply. Please note: due to Dutch regulations, only candidates from EU countries or those with a valid Dutch work permit are eligible for this position.

Delft University of Technology is built on strong foundations. As creators of the world-famous Dutch waterworks and pioneers in biotech, TU Delft is a top international university combining science, engineering and design. It delivers world class results in education, research and innovation to address challenges in the areas of energy, climate, mobility, health and digital society. For generations, our engineers have proven to be entrepreneurial problem-solvers, both in business and in a social context. At TU Delft we embrace diversity as one of our core values and we actively engage to be a university where you feel at home and can flourish. We value different perspectives and qualities. We believe this makes our work more innovative, the TU Delft community more vibrant and the world more just. Together, we imagine, invent and create solutions using technology to have a positive impact on a global scale. That is why we invite you to apply. Your application will receive fair consideration. Challenge. Change. Impact! Faculty of Electrical Engineering, Mathematics and Computer Science The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment - which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.
