Senior Backend Engineer (Golang)

Join BlueThrone as a Senior Backend Engineer to build scalable systems in Golang for a music analytics platform. Enjoy remote work, flexible hours, and the chance to impact millions of users. At BlueThrone, we don’t just build apps. We take indie mobile products and turn them into global powerhouses. 80M+ downloads, 20M+ MAU, $14M+ ARR - we're rewriting the rules of mobile scaling, and we do it lean. We move fast, we own our work, and we build things people actually care about. If you want autonomy and real impact, welcome aboard 💙

• •Architect and evolve backend systems in Golang 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.
• •Maintain and extend our existing Node.js services as part of the ongoing migration to Golang.
• •Catch performance bottlenecks before users ever notice them.
• •Work closely with product, frontend, and data teams - ship fast, iterate faster.
• •Bring fresh ideas, constantly push limits, challenge assumptions, and raise the bar for backend engineering.

• •Prefer freedom over fixed schedules - remote, flexible, unlimited time off.
• •Are naturally curious and love driving real impact for users and the business.
• •Can wear multiple hats - we love experts, but we also value jacks of all trades.
• •Keep things cool, calm, and collected - *save the drama for your llama.*
• •Like challenges and aren’t afraid to roll up your sleeves to win.
• •Believe in working smarter, not harder - focus on productivity and results, not punching the clock.
• •Follow your passion and have fun while doing work that actually matters.

• •5+ years building backend systems at real scale - you’ve seen what works and what breaks when millions of people use a product.
• •Strong Golang on the backend. This is your primary stack, and it shows - concurrency, performance, and backend architecture decisions are second nature to you.
• •Experience designing scalable architectures and REST APIs other engineers actually want to use.
• •Deep knowledge of PostgreSQL, ClickHouse, and Elasticsearch - comfortable with large datasets, unbothered by a bad query plan.
• •Hands-on with Redis and RabbitMQ - you know how to make systems both fast and resilient.
• •Confidence around infrastructure: Nginx, Kubernetes, deployment pipelines.
• •Node.js experience is a HUGE plus. If you've built and shipped with it, great - you'll be right at home working in our legacy codebase.
• •Mobile app experience (iOS or Android) is also a plus.
