Our team </span><span style="font-size: 12pt;">measures and evaluates large-scale Linux systems—from a single rack to data-centre scale. We </span><span style="font-size: 12pt;">don’t just run benchmarks; we determine whether a system behaves correctly, and whether it is </span><span style="font-size: 12pt;">reliable enough to be trusted.</span></p> <p class="p1"><span style="font-size: 12pt;">The work spans designing workloads, building execution systems, and interpreting results. A </span><span style="font-size: 12pt;">measurement is only useful if it leads to a decision.</span></p> <p class="p1"><span style="font-size: 12pt;">You won’t be confined to a narrow role. Some engineers here focus on infrastructure, others on </span><span style="font-size: 12pt;">workloads or analysis—but everyone contributes to understanding system behaviour at scale.
