Clockwork builds high-precision clock-synchronization and latency-observability software—FleetIQ GPU fabric and Latency Sensei—providing sub-microsecond sync, microsecond cluster visibility, hardware-agnostic GPU support, and congestion detection.
<div class="content-intro"><h4><strong>About Clockwork Systems</strong></h4> <p><strong>Clockwork.io – Software Driven Fabrics to increase GPU cluster utilization</strong></p> <p>Clockwork Systems was founded by Stanford researchers and veteran systems engineers who share a vision for redefining the foundations of distributed computing. As AI workloads grow increasingly complex, traditional infrastructure struggles to meet the demands of performance, reliability, and precise coordination. Clockwork is pioneering a software-driven approach to AI fabrics by delivering <strong>cross-stack observability</strong> to catch and quickly resolve problems, <strong>workload fault tolerance</strong> to keep jobs running through failures, and <strong>performance acceleration</strong> that dynamically routes and paces traffic to avoid congestion.</p> <h4>To learn more, visit<a href="https://www.clockwork.io"> www.clockwork.io</a>.</h4></div><p><strong>About the Role</strong></p> <p>We are seeking an experienced <strong>Senior Software Engineer</strong> to contribute to the architecture, development, and scaling of a high-performance network monitoring and observability platform.
