We can't hire everyone… but we can help them shine somewhere brilliant.

At Octopus, we're lucky to attract some incredibly talented humans. And while we can’t bring every talented person into our team, we can help them land somewhere that’s just as mission-driven. That’s why we’re sharing opportunities from MOPO – a company we’ve proudly backed through a strategic investment.

MOPO is transforming access to clean, affordable energy across Sub-Saharan Africa with its pioneering solar battery technology. As part of our partnership to accelerate global electrification and leapfrog dirty fossil fuels, we’re supporting their hunt for exceptional talent. If you share our passion for tech-driven climate solutions, this could be your chance to make a serious impact.

If you’re motivated by purpose, adventure, and the chance to shape a high-impact business, MOPO offers the perfect opportunity. This role is your chance to help build a mission-driven scale-up, backed by Octopus Energy, revolutionising access to clean energy and transport in Africa.

Joining our existing Sheffield-based team, you will be working with other Embedded Software Engineers to match our ambition to radically reimagine transport and energy in Africa.

You’ll be working across a range of disciplines to bring our solutions for energy access to market, including the replacement of petrol generators with swappable batteries and replacing petrol motorbikes with our own electric motorbikes, using the same battery swap system. It’s an exciting and varied challenge.

We’re looking for a senior candidate to join our team to add capacity for our existing projects and to help steer the direction of our product development.

Closing date for applications: 10th August 2025 12pm.

More about MOPO:

Our model is already powering thousands of homes and small businesses - eliminating fossil fuel use and enabling livelihoods.

With backing from Octopus Energy, British International Investment, and Norfund, MOPO is scaling rapidly and is positioned to transform energy access and e-mobility across the continent
