Are you an experienced engineer driven to solve complex technical problems that impact hundreds of developers at scale? Do you aspire to architect and build AI-native platforms that fundamentally transform how engineering teams design, build, and deliver software — where intelligent agents handle the toil so engineers can focus on what matters? The REALM team is looking for a Senior Software Development Engineer to lead high-impact technical initiatives at the intersection of platform engineering and agentic AI. You'll build systems that remove developer friction, streamline workflows, and deliver measurable gains in productivity, efficiency, and operational excellence.
