Principal Process Engineer (USA)

Engineering Department


The Principal Process Engineer will work in the execution of plans for the development and deployment of CPE’s Waste-To-Fuel plants, while also providing technical/engineering contributions to process activities.

With direct reporting to the CTO, and North American President, the Principal Process Engineer will be highly motivated, able to work independently, and have the qualities required to assist the project’s technical objectives and execution strategy effectively and efficiently from a process perspective.

The Principal Process Engineer will typically have relevant technical background to assist in the development and deployment of the waste-to-fuel plant’s design, engineering, construction, installation and commissioning project, among others. 


Clean Planet Energy (CPE) is a cleantech, renewable and alternative energy company, converting non-recyclable waste plastics into ultra-clean commercial grade fuels and circular-oils which emit negligible sulphur and nitrous oxide content, and significantly lower CO2 emissions. CPE’s mission is to remove over 1 million tonnes of non-recyclable plastic waste from our environment every year. We will achieve this mission by continuously devising and implementing sustainable green technologies and processes (such as the Clean Planet ecoPlant) that prevent toxic plastic waste from damaging the earth’s environment and oceans, while also reducing the world’s demand for high-emission fossil fuels and petrochemicals products. We aim to divert non-recyclable waste plastics away from the word’s landfills, incinerators, and oceans - a major environmental win. 

CPE are developing and deploying a series of environmentally friendly EcoPlants; a process plant designed and engineered to accept almost any waste plastic (feedstock) and, through various chemical processes, convert the waste into commercial grade low-carbon, ultra-clean, ultra-low sulphur circular fuels and oils. These can be used as replacements for traditional high-emissions fossil-based fuels, and for also making new plastics. 

Job Description:

The Principal Process Engineer’s skills will typically include a strong background in of Chemical/Process/Refining Engineering. The Principal Process Engineer should have a recognised and relevant Engineering degree and have familiarity with the refining, chemical and petrochemical industries processes. They should also have Professional Engineer / Chartered Engineer status.


Previous experience with pyrolysis, waste-to-energy/waste-to-fuel, gasification, hydroprocessing would be a strong advantage.


The Principal Process Engineer will typically have good organisational and communication skills with the ability to engage positively, as the role requires regular communication with project partners, dealing with proposals, cost estimates, schedules etc.
