We need to make heterogeneous workloads easier to execute, observe, reproduce, and move across different systems without hiding the capabilities or semantics of the infrastructure underneath them.</p> <p><strong>About the role:</strong></p> <p>We’re seeking a <strong>Staff Software Engineer, Runtime Systems</strong> to help design and build this layer.</p> <p>This is a hands-on systems engineering role at the intersection of <strong>distributed systems, runtimes, workflow execution, programming language concepts, and large-scale compute infrastructure</strong>.</p> <p>You’ll work on the foundations that allow complex workloads to move from an abstract description into reliable execution across systems such as Kubernetes, Argo, OSMO, and future execution environments.</p> <p>A major part of the role is deciding where abstraction is useful — and where it creates more complexity. Rather than building another universal workflow engine, you’ll help establish clear contracts between our platform and the systems that execute work, while preserving native capabilities.</p> <p>You’ll operate across architecture and implementation: defining contracts, writing production software, validating assumptions against real workloads, and working closely with platform and infrastructure teams.</p> <p><strong>In this role, you will:</str
