Lead Backend Developer

Cyprus or Remote UG Core

We're looking for a Backend Developer Lead to take technical ownership of the core platform at Ultimate Guitar — the world's largest destination for musicians, with over 14 million monthly active users.

What is in it for you?

• Ownership from day one. You'll shape the technical direction of the platform, not just execute tickets. We trust our leads to drive decisions.
• A team that values craft. We allocate dedicated capacity to technical debt, run regular architecture discussions, and take engineering quality seriously — not just velocity.
• Room to grow. Direct path to broader engineering leadership as the company scales, with full support for learning new tools and practices.
