Sheffield, Sheffield, United Kingdom Octopus Energy Group Full time £40,000 - £80,000 per year

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.

Joining their existing growing Sheffield-based team, you'll be working to match their ambition to radically reimagine transport and energy in Africa through the development of the MOPO Platform - the digital backbone that powers our energy distribution network across the continent.

You'll be working across the full stack using Python/Django, , and MariaDB to build and maintain the platform that manages our solar hubs, battery networks, and the thousands of customers they serve daily. It's an exciting and varied challenge where your code directly

impacts lives and livelihoods.

Mopo are looking for a candidate to join their team to add capacity for their rapidly scaling platform and to help steer the direction of their technical architecture.

  • Build intuitive and responsive web interfaces that work reliably in challenging connectivity environments
  • Integrate third-party APIs and services to extend platform capabilities
  • Conduct code reviews, mentor team members, and champion best practices
  • Troubleshoot technical issues to ensure minimal disruption to our operations across four countries
  • Participate actively in Agile processes, contributing to planning and refinement sessions
We would like to hear from you if you have the following experience...
  • Strong proficiency in Python and Django for backend development
  • Good working knowledge of (or similar Javascript framework, e.g. React)
  • In-depth knowledge of MariaDB and SQL

The following would be a strong plus...
