Data Steward - Sequencing & Phenotyping

Role
TU Delft & CropXR are looking for a Data Steward with a strong affinity for plant research, sequencing and phenotyping data. You will work closely with researchers to make sure that valuable research data is well organised, understandable, findable and reusable. You will be a bridge between research, data and the CropXR data infrastructure.
What you do

Your work includes

• Supporting researchers with data management throughout the research lifecycle, from experiment design and data collection to publication and long-term reuse.
• Working with sequencing and phenotyping data, including sample and plant-material information, experimental metadata, sensor and imaging data, and files such as FASTQ, BAM and VCF.
• Helping researchers describe experiments and datasets using consistent metadata and relevant standards, including MIAPPE, ISA and the CropXR Metadata Management Procedure.
• Making research data more FAIR by establishing practical conventions for file organisation, naming, identifiers, metadata, versioning and documentation.
• Reviewing datasets with researchers, identifying missing information, and advising on suitable formats, repositories, access conditions and data publication, including submissions to repositories such as ENA or NCBI.
• Preparing and connecting datasets for the CropXR Resilience Hub and contributing to CropXR-wide data-management guidelines and best practices.

What you bring
You have a completed university degree at MSc level, or an equivalent level of academic training, in a relevant field such as plant sciences, biology, bioinformatics, biotechnology, genetics, computational biology, data science or a related discipline. You have a good understanding of how biological research data is generated and used. You do not need to develop sequencing pipelines or phenotyping platforms yourself, but you should understand sequencing and phenotyping data well enough to communicate effectively with both researchers and technical teams.
You are comfortable with metadata, FAIR data principles and research data repositories. Experience with relevant standards and data-management approaches is an advantage, but a willingness and ability to learn is more important. Some familiarity with structured data or scripting, for example Python, R, command-line tools, JSON, CSV or APIs, is useful for understanding and validating datasets. This is not primarily a software-development role. You communicate clearly in English and are comfortable working in a collaborative, interdisciplinary research environment.
You combine scientific curiosity with a pragmatic, service-oriented mindset. You enjoy talking to researchers about their experiments, asking the questions that uncover missing context, and translating FAIR data principles into practical actions. You are comfortable working across disciplines and can communicate with experimental scientists, bioinformaticians, data scientists and infrastructure developers.
Success means that good data management becomes a natural part of the CropXR research workflow. Datasets are well described, can move smoothly into analysis and repositories, and remain understandable and reusable by other researchers.
What you get

• Duration of contract is 2 years. Temporary.
• A job of 38-40 hours per week.
• A salary based on Scale 10 of the CAO for Dutch Universities with a salary between €3706 - €5760 gross per month based on a fulltime contract (38 hours), plus 8% holiday allowance and an end-of-year bonus of 8.3%.
• A pension scheme via the ABP.
• The possibility to compile an individual employment package every year.
• Discount with health insurers on supplemental packages.
• Flexible working week.
• Every year, 232 leave hours (at 38 hours). You can also sell or buy additional leave hours via the individual choice budget.
• Opportunities for education, training and courses.
• Partially paid parental leave.
• Attention for working healthy and energetically with the vitality program.

About the employer
TU Delft (Delft University of Technology) is built on strong foundations. Its engineers are known as creators of the Dutch waterworks and as pioneers in biotech. TU Delft combines science, engineering and design. It delivers results in education, research and innovation to address challenges in the areas of energy, climate, mobility, health and digital society. For generations, its engineers have proven to be entrepreneurial problem-solvers, both in business and in a social context.
At TU Delft, diversity is one of the core values. The university works to be a place where you feel at home and can flourish. It values different perspectives and qualities. Together, people imagine, invent and create solutions using technology to have a positive impact on a global scale. Your application will receive fair consideration.
The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Together they reinforce each other and drive the technology used in daily life, such as the electricity grid. The faculty helps make the grid completely sustainable and future-proof. It develops the chips and sensors of the future and sets the foundations for the software technologies that run on this new generation of equipment, including AI. It also applies mathematics, for example to map disease processes using single cell data and to simulate ash plumes after a volcanic eruption. The faculty educates engineers and has labs and facilities that underline its international position. In total, more than 1000 employees and 4,000 students work and study at the faculty.
