We're recruiting a new CTO!

Are you a smart contract specialist who wants to apply his/her skills to solve social and environmental problems? Look no further! 


Job Title: CTO


Job Location: Remote (ideally based in Europe) with periodic travel to Africa 


Start date: TBD


Benefits: Between 25,000 USD and 34,000 USD the first 8 months and 25% - 34% vested equity. You will be expected to earn sweat equity during periods of low cash flow. 



Gaichain, a UK registered startup, is dedicated to applying blockchain technologies to support ecosystem restoration in a way that benefits both the rural poor and international companies, governments and even individuals that invest in ecological restoration, particularly in the tropics. Our core team consists of two forest governance experts with a combined 20 years of experience managing complex environmental programmes with various organisations including UNEP, World Resources Institute, Dian Fossey Gorilla Fund, and the Environmental Investigation Agency. Our team also includes an advisor/investor with over 10 years of relevant tech and management experience. 


In terms of traction, we have implemented FAO and EU funded pilot projects in Ivory Coast to support ‘sustainable’ cocoa and charcoal supply chains. We are launching a new initiative in collaboration with a global environmental organisation that focuses on developing efficient and transparent ecological restoration payment systems. Leading the development of that system on the Algorand blockchain will be your first responsibility. 


The CTO will focus on coding until our team expands and the role requires more coordination. He/she will work closely with the team to not only build products but also design them to ensure a solid product-market match.
