About Mazi

Mazi Mobility is transforming Africa’s transport infrastructure through intelligent electric mobility solutions. We build and operate interoperable battery swapping stations for electric motorcycles, underpinned by a smart digital platform with ambitions to build a multi-battery AI optimization system.

Since 2021, we have been a market leader in charging and e-mobility. In a $30Bn e-mobility market opportunity, we see battery swapping and charging as a key in enabling the development of the sector.

We’ve partnered with various e-mobility companies in the region and see ourselves as building the backbone of what will be the connective system of various countries on the continent and beyond. With a young but highly experienced and motivated team, Mazi is focused on our mission in powering Africans into an electrified future.

As we scale across Kenya and the continent, we’re looking for a visionary Chief Technology Officer (CTO) to lead our engineering, AI, and software efforts - join us to move people, data and things!

Our values

Experience the customer – Mazi exists for its customers; by experiencing the customer, we are committing to live in their shoes, understand their struggles and help them at every turn.

Ubuntu – A team is only as strong as its weakest link; we are a functional unit – focused and dedicated. We are passionate people who care about making a difference and understand we must help each other achieve our ambitious mission.

Be Direct and Accept – We celebrate our wins and don’t shy away from our mistakes. We have hard conversations with empathy and optimize for long-term success and company longevity. Opinions are valid, but we don’t take things personally if they don’t always align. We are quick to make decisions and combine multiple good ideas into singular great ones.

Execution, Execution, Execution (3EX) - We are outcome-based, relentlessly pursuing our goals. We are building a meritocracy. We go beyond most companies for our customers; we care about the what, the why, and the how. Excellence and attention to detail are blended with adaptability and pace. We have a bias to action.

Founding the Future – Mazians are never really satisfied. There is always a faster, better, kinder way to do what we do. We are not scared to go first and fail. We are obsessed with the growth and development of our products, people, and customers. We are predicting the future because we are actively shaping it.
