Senior Backend Engineer

Overview

Senior Backend Engineer - Node.js, TypeScript

At BlueThrone, we don’t just build apps. We scale indie mobile products into global powerhouses. With 80M+ downloads, 20M+ MAU, and $14M+ ARR - we’re rewriting the rules of mobile scaling. We’re a lean, high-performing team that thrives on speed, ownership, and building products people actually care about. If you’re excited by autonomy, global impact, and solving complex problems at scale, welcome aboard. But if you’re looking for structure, predictability, a 9-5 job, or hand-holding - this won’t be your vibe.

Note : fully remote role with flexible hours, unlimited time off.

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.”

• Architect and evolve backend systems that support millions of active users—from designing architecture to ensuring smooth operation 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, 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, push limits, challenge assumptions, and raise the bar for backend engineering.
