What we’re looking for 🎧

You’ll be working on one of our flagship products : an analytics-driven music platform that changes how millions discover, interpret, and connect through music. Already loved by users worldwide, the product is entering a new stage of rapid growth.

As Senior Backend Engineer , you’ll own the systems that power this growth.

This isn’t a maintenance role.

We’re not looking for someone to “keep APIs alive.”

We’re looking for someone who :

▸ takes initiative,

▸ thrives in fast-changing environments,

▸ isn’t afraid to zoom out to design complex systems or zoom in to perfect a single query.

You'll design and scale the backend, make bold architectural calls, and build APIs that frontend engineers love to use. You’ll dive deep into data flows, caching, and performance - always thinking about how backend decisions shape the user experience.

You value clarity over complexity, impact over showmanship, and you care about how your work affects millions of real users.

What you'll do

• Architect and evolve backend systems that support millions of active users - from designing architecture to making sure everything runs smooth at scale.
• Build APIs engineers love - clean, reliable, and intuitive, so the frontend team can move fast without friction.
• Work with complex data flows, caching, and messaging, always balancing performance with simplicity.
• Detect and resolve performance bottlenecks before users notice.
• Collaborate closely with product, frontend, and data teams to ship fast and iterate faster.
• Bring fresh ideas, constantly push limits, challenge assumptions, and raise the bar for backend engineering.
