Senior Software Engineer, Capacity & Efficiency

Join us in building the future of finance. Our mission is to democratize finance for all. The Capacity & Efficiency Engineering team focuses on building software to manage, govern, and reduce Robinhood’s AWS cloud spend. The team operates at the intersection of cloud infrastructure, data engineering, and FinOps, owning systems that attribute cloud costs to real consumers, detect spend anomalies, and surface actionable insights. This is a high-visibility team whose work directly impacts company-level cost efficiency and long-term scalability! As a Senior Software Engineer on the Capacity & Efficiency Engineering team, you will design and build systems that make cloud costs transparent, predictable, and controllable. You’ll work closely with engineers, Data Science, and Infrastructure partners to develop tooling that detects inefficiencies, tracks over-provisioning, and enables teams to take concrete action to reduce waste across AWS and Kubernetes environments. You will work across the full infrastructure stack, from AWS cloud platform, networking to application-level performance to bring efficiency up on the large micro service architecture powering Robinhood. You will help with building the telemetry, cost attribution, and optimization frameworks that ensure every dollar of our infrastructure investment delivers maximum value. This is a high-impact, cross-functional role at the intersection of systems engineering, financial optimization, and Distributed systems.
