Your primary responsibility will be building highly performant backend systems and keeping them reliable at scale. This is a hybrid backend/SRE role: you'll write the services and you'll own how they behave in production.</p> <p>This role requires strong experience in backend software development, particularly API development and scaling existing systems in both Go and Node.js, paired with a genuine interest in reliability engineering. You'll design and implement scalable, high-performance backend systems, maintain their SLOs, and take ownership of features from concept through deployment and steady-state operation.</p> <p>A key aspect of this role involves a deep understanding of scaling and operating distributed systems, allowing us to multiply our capacity safely and efficiently as our user base continues to grow rapidly.</p> <hr> <h3>What you'll do:</h3> <ul> <li>Design, develop, and optimize backend systems for real-time data processing and web services, with reliability, latency, and cost as first
