You'll focus on architecting and building new systems as well as improving existing ones for a platform that supports millions of users globally. You'll have the autonomy to shape technical solutions, influence architectural decisions, and own services throughout their lifecycle.\nWhat You'll Do\nDesign, build, and maintain backend infrastructure, APIs, and services at scale.\n\nOwn the architecture and implementation of distributed systems behind high-volume, low-latency APIs.\n\nSolve hard scalability, latency, and performance problems in live production systems.\n\nLead system design discussions and shape the direction of our backend architecture.\n\nSet the best practices for backend development-throughput, reliability, and latency.\n\nValidate performance through automated testing, benchmarking, and production-driven improvements.\n\nTrace production issues across services and the full stack, and ship fixes that durably improve reliability.\n\nWhat We're Looking For\n5+ years of relevant industry experience.\n\nBS/BA degree in Computer Science or equivalent practical experience.\n\nExperience designing, building, scaling, and maintaining core backend components\n\nAbility to solve complex design, scalability, latency, or performance problems in high-throughput, low-latency production systems.\n\nProduction experience with Java, Rust\n\nExperience in cloud-native environments, particularly AWS.\n\nExperience with managed Kubernetes platforms such as Amazon EKS is a plus.\n\nComfortable working across the stack, with a willingness to dive into infrastructure and platform challenges when the problem calls for it.\n\nExperience building highly available and scalable distributed systems.\n\nYou're a self-starter who takes ownership, moves fast, and knows when to obsess over the details-and when it's time to ship.\n\nCuriosity about emerging technologies and a desire to continuously learn and explore new ideas.\n\nWeb3 experience, a plus\n\nFounded a company or built side projects, a plus\n\nExperience in startups, a plus\n\nBenefits & Perks\n Private
