Job Description

Senior Android Engineer at MOPO

About MOPO

MOPO is on a mission to enable renewable energy access in underserved markets. Already operating in Nigeria, DRC, Sierra Leone and Liberia, our solar power stations distribute energy through proprietary MOPO Batteries managed by a network of local agents. 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.

What is the role

Joining our growing team, you'll be working to match our ambition to radically reimagine transport and energy in Africa through the development of MOPO's core Rental App, as well as supporting the development of the wider MOPO Platform - both critical tools that empower our network of local agents to manage battery distribution and customer relationships across the continent.

You'll be building and maintaining Android applications that work reliably in challenging connectivity environments, enabling thousands of agents to run their businesses and serve their communities. Your work will directly interface with our MOPO Platform backend, creating seamless experiences that drive our energy distribution network. It's an exciting and varied challenge where your code directly impacts lives and livelihoods.

We're looking for a senior candidate to join our team to enhance our mobile capabilities as we rapidly scale across Africa and to help shape the technical direction of our mobile architecture.

The role will interest you if:

• You're excited by the prospect of building technology that transforms off-grid energy access in Africa
• You have a passion for creating mobile applications that empower local entrepreneurs and improve community access to clean energy
• You are interested in working in a truly collaborative environment where you'll work closely with backend engineers, product designers, and stakeholders across our operations

On a given day, you'll likely…

• Work collaboratively across the company to continuously refine how our mobile applications can create the greatest impact for agents and customers
• Design, develop, and maintain features for our Android applications that enhance agent productivity and customer experience
• Build robust offline-first functionality to ensure our agents can operate effectively regardless of connectivity
• Optimise app performance for a wide range of Android devices common in our markets
• Integrate with our Django/Python backend APIs to synchronize data and enable real-time operations
• Implement intuitive UI/UX that works for users with varying levels of digital literacy
• Conduct code reviews, mentor team members, and champion Android best practices
• Debug and resolve issues reported from the field 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 experience in the following areas:

• Strong proficiency in Kotlin and/or Java for Android development
• Experience with Android SDK, Android Studio, and modern Android architecture patterns (MVVM, MVP)
• Expertise in offline-first mobile architectures and data synchronization strategies
• RESTful API integration and handling of network connectivity challenges
• Android UI/UX best practices and Material Design guidelines
• Version control systems (e.g., Git) and CI/CD pipelines for mobile apps
• Mobile app security best practices and performance optimization
• Experience with Android debugging tools and crash reporting systems
• Google Play Store deployment and app lifecycle management

Any of the following would be a strong plus:

• Experience with Python/Django or willingness to collaborate closely with backend systems
• Experience with Bluetooth Low Energy devices
• Experience with mobile payment integrations or fintech applications
• Background in building apps that work well on lower-end devices and limited connectivity

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 we offer to all of our employees if they are interested.
