Who we are


Zhilang Technology Co., Ltd. is a subsidiary of Circle Gas Ltd., a UK company. Our mission is to bring affordable LPG cooking into millions of homes, starting in Kenya and Tanzania. Our cutting-edge Pay-as-you-go Technology makes the switch from unhealthy, environmentally damaging charcoal and kerosene to clean, safe LPG possible. The application of our R&D in IoT, AWS, microfluidics, semiconductors and data analytics will transform the lives of millions of families who wouldn’t otherwise be able to afford gas for cooking.

Creative problem solving is key to our success and maintaining our position as the world’s leading pay-as-you-go LPG Smart Meter company.
  • Honesty: if you have feedback, we want to hear it! We value transparency and want to help overcome challenges and learn from our mistakes.


We are looking for an analytical, business-minded machine learning engineer to structure and analyze big data sets from our global customers.
