Volledige vacaturetekst

From energy-neutral operations to resource recovery — the next generation of wastewater treatment is here. Be part of the shift toward smarter, cleaner systems

Job description 

Are you passionate about creating smart, sustanable water systems? Join a dynamic, interdisciplinary team of different Dutch Waterauthorities and TU Delft and help design the wastewater treatment plant of the future. Different sewage treatment technologies can be combined to achieve the most optimal process scheme for climate neutral wastewater treatment, maximum resource recovery, and excellent treated water quality, ready for reuse. The question is how effective these combinations of technologies will be in practice. We challenge you to quantitavely analyse these complex wastewater treatment processes, with an open mind for innovation and a keen eye for practical applicability and design the most optimal treatment plant of the future.

As an EngD candidate, you have a strong affinity with modeling water treatment processes, understand the basic principles of both biological and physico-chemical treatment techniques, and can translate this knowledge into insightful computational models. Rather than adhering to traditional methods, you are eager to contribute to exploring alternative pathways for the treatment of the future — pathways centered around innovative combinations of technologies.

Job requirements 

You are a curious and pragmatic engineer who thrives in complex environments and wants to make a real-world impact.

You bring:

• A completed MSc in Environmental Technology, Chemical or Civil Engineering, Water Technology, or a related field
• A solid understanding of biological wastewater treatment (e.g. nutrient removal)
• Interest in — or experience with — advanced physico-chemical techniques (e.g. ozonation, activated carbon, membrane filtration)
• Affinity with process modeling and simulation tools, or the ambition to develop these skills
• Strong analytical and communication skills — able to explain complex findings to both technical and non-technical audiences
• A collaborative mindset and a hands-on approach

Bonus points if you:

• Have experience with modeling tools (e.g. SUMO, WEST, GPS-X) or programming (e.g. Python, MATLAB)
• Are familiar with European water policy and regulation
• Speak Dutch (not required)
• Can demonstrate English proficiency*

*If English is not your first language and your MSc degree was not obtained in English, please include a valid TOEFL (≥100) or IELTS (≥7.0) certificate (not older than 2 years).

Conditions of employment 

• A full-time, 2-year contract, with a go/no-go evaluation after the first year.

• A job of 38 hours per week. 

• A gross monthly salary starting at €2,901 in year one, increasing to €3,378 in year two (scale TOIO+, in accordance with the Collective Labour Agreement for Dutch Universities), based on a fulltime contract (38 hours), plus 8% holiday allowance and an end-of-year bonus of 8.3%.  

• An excellent 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. 
• Plenty of opportunities for education, training and courses. 
• Partially paid parental leave 
• Attention for working healthy and energetically with the vitality program.
