Senior Backend Engineer (Golang)

What you'll do

• 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.

What you bring

• 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.
