The Team behind GEHECO’s Innovation
Our dedicated team is passionate about driving sustainable solutions.
Team
The GEHECO team consists passionate individuals who believe technical solutions can make a great difference in helping our planet become more sustainable. From our office and workshop in Delft, we develop our technology and run our projects. We are based in the YES!Delft building and enjoy the YES!Delft community activities as trainings and the Friday drinks.

Onno Bierhoff
CEO & Founder

Bart van de Kerk
CTO
Eagerly using my background in engineering and project management to develop the GEHECO technology in a fast and controlled way. Heading to a market-proof product and continuously optimising the performance and reliability of our products.

Mohamad Alkenaan
Development Engineer
I leverage my expertise in scientific research to analyze procedures, set up lab tests and validate hypotheses. I also apply my mechanical engineering skills to 3D modeling and concept testing.

Anton Deken
Development Engineer
I use my experience from Aeronautical Engineering in the mechanical design of the GEHECO drilling system. Specializing in rapid prototyping and manufacturability.
Join GEHECO
Are you passionate about technology and the environment? We are seeking enthusiastic individuals eager to gain hands-on experience and make a difference in the world of sustainable technology.
“It is great to work at a startup. We are designing something that doesn’t exist yet. That means researching new ideas, coming up with solutions, testing, discussing with each other, creating prototypes, and starting all over again. I find this phase incredibly challenging and I haven’t been bored a single day since I started working at GEHECO.”
Mechanical Engineer
Key Responsibilities / What you will do:
- Create design solutions while developing the product; during the development of our products, problems will have to be solved with innovative design solutions. You will be responsible for preparing the design to bring the development further.
- Detail design of prototypes;pragmatically create the drawings required to create prototypes
- Build prototypes; you will make the prototypes with tools provided in the (very well equipped) mechanical workshop. Based on the concept design, you create a working tool that you will build and assemble yourself and test it in the lab and if successful also in the field.
- Test & Learn: when testing the prototypes, you will engage in several roles, to make the test successful and optimize the learning effects.
- Collaboration; we are a small team where every individual counts. We need your analytical thinking and problem-solving skills to improve our product and drive our projects forward.
- Flexibility; Our small team does not allow us to set strict fixed roles, so while your main tasks will be as described, every individual is required to also take various other tasks as required by the company.
- Engage in problem-solving exercises, learn by doing on a daily basis and contribute fresh perspectives to the development of the GEHECO product.

Intern: High Pressure Water Jets Research
Key Responsibilities / What you will do:
- Identifying the dominant flow mechanisms responsible for upward particle transport
- Defining dimensionless criteria that determine when stable upward transport occurs
- Investigating how nozzle geometry (internal/external) and flow conditions influence jet formation and material transport
- Establishing minimum design requirements for effective jets
- Creating a theoretical model linking nozzle design,expected jet behavior, and particle transport

Part-time: Electronics and Control Engineer
Available per 1/9/26
Key Responsibilities / What you will do:
- Design and create sensors and control electronics; pragmatically create the control components and sensors (hardware) that allow the drill to be controlled automatically. Make the software to do the control. You will use Arduino’s, raspberry Pi’s etc to do so. You will devise sensors and electronics for the drilling process.
- Test prototypes; you participate in frequent tests in order to validate your designs and designs other team mates come up with.
