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.

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.

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!
