Job description

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, Vue.js, 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.

Working location

The role is based primarily in our Sheffield HQ, with up to two days working from home if desired. Occasional international travel to Sub-Saharan Africa is entirely optional, but is something they offer to all of their employees if they are interested.

The role will interest you if...

• You’re excited by the prospect of transforming the off-grid energy and e-mobility market in Africa
• You have a passion for improving the lives of the customers who use our products
• You are interested in working in a truly full-stack team

On a given day you'll likely...

• Work collaboratively across the company to continuously refine how our platform can create the greatest impact, scale efficiently, and operate reliably for our users
• Design, develop, and maintain features for the MOPO Platform that enhance functionality and user experience
• Optimise database performance and ensure efficient data storage and retrieval for our growing network
• 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 Vue.js (or similar Javascript framework, e.g. React)
• In-depth knowledge of MariaDB and SQL
• RESTful API design and development
• Version control systems (e.g., Git) and CI/CD pipelines
• Web security best practices and performance optimization
• Server deployment and maintenance (e.g. nginx, cron, package managers)
• Strong debugging skills (e.g. PyCharm debugger, pdb, Sentry)

The following would be a strong plus

• Knowledge of IoT or hardware integration
• Experience with distributed systems or offline-first architectures
• Background in energy, mobility, or fintech sectors

Closing date for applications: 17th November 2025 12pm.
