The mission of The Ocean Cleanup is to develop and scale technologies to rid the world’s oceans of plastic. The goal of the Rivers team is to tackle the 1000 most polluting rivers around the world by developing and implementing river cleaning systems. Working in the Rivers team, your role will be to take the technical lead in deployment projects. With your engineering background, preferably in naval, offshore or civil engineering, and your international and multicultural experience, you will help us intercept as much plastic as possible and prevent it reaching the oceans. 

Each river is unique, and therefore each river has its own technical challenges when implementing solutions. The Project Engineer is responsible for ensuring the technical fit and for (re)designing the solution to be most effective. - Onno van de Sande, Integrated River Solutions Director 


With a number of Interceptors already installed, the Rivers team is now working on new projects and new solutions. To prepare for scale-up to dozens and then hundreds of rivers, it is important to recognize unique river requirements early, so that the right solution is selected and engineered to perform optimally.

Designing the final solution, being able to explain the design and design choices to a broad variety of stakeholders and having the hands-on mentality to get your hands dirty when required - these are the key attributes to be successful as Project Engineer. 

We are looking for highly motivated Project Engineer with a strong connection to water or marine environments (ships, offshore, waterworks) who wants to take on the challenge to design and implement the best technical river cleaning solutions around the world. 


  • Responsible for adjusting existing Interceptors to be optimal for local environments and circumstances, and designing tailor-made solutions if required 
  • Performing high-level calculations and simulations to understand basic principles of concept designs and to quickly assess ideas before handing them over to engineering 
  • Perform optimization studies to discover the best performing system design: bring a concept design from the early concept phase to maturity, meeting performance criteria and scale-up requirements 
  • Manage and execute the conception process from ideation to completion of basic engineering 
  • Ensuring tight and smooth cooperation between R&D and engineering groups 
  • Preparing and monitoring work scopes for testing and assessment of concept designs and answering research questions. Work scopes include (hydrodynamic) analyses, lab tests, and field tests (in a broad sense) 
  • Keeping a record of developing knowledge within our project while defining knowledge gaps. Prioritizing and providing scopes to the engineering team or third parties to fill those knowledge gaps 
  • Feeding newly developed knowledge back into the concept development


  • Bachelors or Master's degree in marine/offshore/dredging engineering (or comparable working experience in combination with another engineering master's degree) 
  • 5-10 years of relevant work experience in technology development and implementation, preferably in an innovative environment 
  • Ability to clearly present and explain technical design considerations to other engineers but also to other non-technical stakeholders 
  • Ability to quickly build an understanding of unique local river requirements 
  • Hands-on and practical approach to engineering. Willingness to travel to site (20-30%) 
  • Pays attention to detail while keeping the broader picture in mind 
  • Fluent in English


  • Able to quickly get to the essence of a technical challenge and investigate, calculate and analyze the most relevant and important aspects to help direct towards a solution 
  • Performs well in a fast-paced and challenging environment 
  • Curious, creative, and determined to deliver 
  • Flexible team player 
  • Strong communication skills 
  • Intrinsic motivation to work on our ambitious and meaningful goal
