Why this role matters

At OVO, our mission is simple but huge: solve the climate crisis through Plan Zero.

As a Senior Software Engineer, you’ll own the end-to-end development of complex, core systems that push our technology forward. In this role, you’ll lead technical initiatives, make critical design decisions, and collaborate across multidisciplinary teams to bring AI-driven products directly to market via mobile applications.

What you’ll be doing

Reporting directly to the Delivery & Growth Lead, you’ll drive engineering excellence and power our green mission:

Technical Leadership & Architecture: Drive the architectural vision for key features, design robust and scalable systems, and shape our technical roadmap.

Engineering Excellence: Champion software best practices by writing clean, performant code, conducting rigorous code reviews, and implementing robust automated testing.

Product Execution & Delivery: Translate complex technical projects into clear, executable tasks within an Agile framework, resolving blockers to keep delivery moving.

Mentorship & Community: Lead, mentor, and elevate fellow engineers while actively contributing to OVO’s wider engineering community through workshops and knowledge sharing.

What you’ll bring

You don’t need to tick every single box to apply - if you have the core toolkit and a passion for problem-solving, we want to hear from you!

The Essentials

Frontend Frameworks: Proficiency in modern frontend technologies such as React.js and/or React Native.

Leadership & Communication: A proven track record of mentoring engineers, driving technical initiatives, and collaborating in high-ownership team settings.
