About the role

Join us in building the future of finance. Our mission is to democratize finance for all. An estimated $124 trillion of assets will be inherited by younger generations in the next two decades. The largest transfer of wealth in human history. If you’re ready to be at the epicenter of this historic cultural and financial shift, keep reading. About the team + role We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards. The Load and Fault team sits within Robinhood's Developer Infrastructure organization, with a mission to give every engineering team the tools they need to test their services under real-world conditions before those conditions test them in production. We build the platforms and frameworks that enable load testing, fault injection, and resilience validation at scale — treating reliability as a developer productivity problem, not just an operations one. Our work directly raises the quality bar for every service Robinhood ships, and we partner closely with engineering teams across the organization to make resilience testing a seamless part of the development workflow. As a Senior Software Engineer on the Load and Fault Environments team, you will design and build the infrastructure that lets Robinhood's engineers simulate load, inject faults, and validate system behavior under stress — at the scale of a fast-growing financial platform. You'll own meaningful components of the load testing and fault injection platform, write production-quality code, and collaborate with engineers across infrastructure and product teams to ensure the tooling you build gets adopted and drives real reliability improvements. This is a high-impact individual contributor role where your work directly shapes how Robinhood builds resilient systems! This role is based in our Menlo Park, CA office, with in-person attendance expected at least 3 days per week. At Robinhood, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams. What you'll do • Design, build, and maintain load testing and fault injection infrastructure that enables engineering teams across Robinhood to validate system resilience as part of their standard development workflow. • Own platform components end-to-end — from architecture and implementation through testing, deployment, and iteration — ensuring the tools you build are reliable, scalable, and developer-friendly. • Collaborate with infrastructure and product engineering teams to understand their resilience testing needs, translate those needs into platform capabilities, and drive adoption of shared tooling. • Contribute to defining steady-state hypotheses, blast radius controls, and fault injection primitives that make chaos experiments safe, repeatable, and actionable at scale. • Write clean, well-tested code and participate in technical design discussions that raise the engineering bar across the team. What you bring • 5+ years of software engineering experience with strong coding skills in Python, Go, or a similar language — this role requires building production systems, not just operating them. • Experience designing or contributing to load testing, fault injection, chaos engineering, or developer productivity infrastructure in a distributed systems environment. • Solid u
