Senior Data Analyst / Software Engineer

You have a relevant HBO or WO degree, for example in computer science, data science, engineering, applied mathematics, physics, or a similar field.

You have several years of relevant experience in data engineering, analytics engineering, software engineering, or technical data analysis.

You have strong Python skills and experience building maintainable software or analysis applications.

You have experience with time-series data, APIs, databases, and data processing.

You have experience with back-end development and delivering practical interfaces or dashboards.

You are analytically strong and can immerse yourself in physical and operational systems.

You can convert exploratory analyses and prototypes into robust, reusable solutions.

You can make pragmatic technical choices within a growing organization.

You are professionally proficient in English. Dutch is valuable, but not a requirement.

You can clearly explain technical choices to colleagues without a software background.

Experience with data from energy, industry, building technology, greenhouse horticulture, or IoT.

Knowledge of statistics, experimental design, and uncertainty analysis.

Experience with cloud infrastructure, automated testing, and deployment.

Experience with Python, SQL, and relevant data and visualization tools.

Experience with time-series and sensor data.

Experience converting technical or scientific calculation methods into software applications.

Experience mentoring junior analysts or developers.

Interest in thermodynamics, energy systems, or greenhouse horticulture.

Want a key role in the development of our data and software environment.

Want a broad role in which data engineering, analysis, software, and product development converge.

Want direct involvement with physical systems and practical projects.

Want the opportunity to help determine technical choices, standards, and ways of working.

Want collaboration with engineers, researchers, growers, and technology partners.

Want the opportunity to mentor colleagues and further build the Data & Software function.

Want a suitable salary and benefits package based on your experience.

A hybrid working environment around our office in Rotterdam.

Do you want to deploy data and software for a physical technology that contributes to more energy-efficient and sustainable greenhouse horticulture?

Thermeleon is developing an innovative Heat Battery for high-tech greenhouses. Our projects yield diverse climate, energy, sensor, and product data. This data forms the basis for reliable analyses, customer insights, and further improvement of our technology.

We are looking for a Senior Data Analyst / Software Engineer who combines strong analytical skills with practical software development. You will help build a scalable data and software environment: from data ingestion and quality control to dashboards, analysis processes, and technical tools.

You do not work remotely from the physical product. You work directly with engineers, researchers, and analysts on applications for greenhouse and customer projects.

You design and develop reliable data flows for sensors, technical systems, and other relevant data sources.

You structure the storage, processing, and availability of project and time-series data.

You develop methods to effectively combine data from different systems and formats.

You automate checks, monitoring, and error handling.

You establish practical standards for data quality, documentation, traceability, and version control.

You ensure that data is usable and available for analyses, dashboards, technical evaluations, and product development.

You take into account appropriate access and protection of customer data and internal knowledge.

You develop reusable analysis processes for climate, energy, and product data.

You analyze time series and help explain differences between situations, periods, and projects.

You support the development of reliable comparisons, baselines, and performance calculations.

You translate statistical and technical results into clear insights for engineers and other colleagues.

You review and improve the analyses of the Data Analyst.

You collaborate with Performance and R&D to convert technical methods into reliable analyses.

You determine which analyses can be automated and where substantive interpretation remains necessary.

You build software that enables technical teams to analyze projects faster and more consistently.

You develop practical tools for calculations, scenario analyses, project evaluations, and technical decision-making.

You convert prototypes and research results into reliable, maintainable software.

You integrate relevant internal and external calculation methods into usable applications.

Where relevant, you develop connections with external systems and platforms.

You contribute to both the technical backend and user-friendly interfaces.

You ensure that technical knowledge is applied in software in a safe and manageable way.

You develop internal and customer-oriented dashboards for monitoring and evaluating projects.

You build clear visualizations of climate conditions, energy use, and product performance.

You automate recurring reports while maintaining traceable calculations and assumptions.

You ensure that dashboards and reports are understandable for engineers, growers, and commercial colleagues.

You develop reusable reports for different types of projects and customers.

You monitor that customer-oriented results align with the underlying validated methods.

You make technical choices that suit a growing organization and future scaling.

You introduce practical standards for software development, documentation, testing, and version control.

You mentor the Data Analyst or working student and review more complex analyses and development work.

You help prioritize software and data work based on needs from customer projects, engineering, and product development.

You determine when a quick analysis is sufficient and when a scalable software solution is required.

Where necessary, you collaborate with external specialists.

You help build the broader Data & Software function within Thermeleon.

Like working at the intersection of data analysis and software development.

Want your work to have an impact on a physical product and real customer projects.

Can bring structure to data and systems that are still under development.

Consider both analytical correctness and usability and maintainability to be important.

Like helping less experienced colleagues to develop.

Want to build practical tools that are actually used within projects.
