Senior Full Stack Engineer

Role Summary 

Kofa is building a mobile and portable battery network to provide reliable energy access for our customers. The initial use case for these batteries is to power electric motorcycles, and ultimately any relevant use case. To achieve this, we are building a network of charging stations where customer can swap their depleted batteries for fully charged ones. We are starting in Ghana, but then looking to scale across Sub-Saharan Africa and beyond. 

We are looking for a Full Stack Engineer to lead the design and build of an entire system covering Enterprise Resource Planning through to monitoring and control of the assets connected into the Kofa platform.  This starts with the first customer touch point through to ordering product and delivering this product to our customers. Once a device such as a battery is connected into our system, its needs to run autonomously, responding to control commands, whilst providing full visibility on a range of data points, giving customers useful insights and analysis. Some parts of this system will rely on 3rd Party software and some parts will need to be built in house, with the ultimate objective of creating a brilliant and seamless customer experience. This would also include sending over-the-air software updates across the variety of connected devices to deliver new features and improvements.

This will require a diverse software stack across a variety of systems and applications such as integration to 3rd Party systems, embedded systems, cloud services, web apps and IOT protocols. We are looking for highly motivated people to help build these systems and join us on our journey to change the way people access energy, with a customer first approach.
