Description

• CIQ is seeking a highly experienced Senior or Principal Performance Engineer to own and drive system-level and application-level performance across our product portfolio. • Be the standard-bearer for performance at CIQ and ensure our performance-focused solutions are the fastest in the industry. • Involve closely with Fuzzball, integrating workloads through it. • Design, develop, and maintain comprehensive benchmarking frameworks spanning OS, kernel, and application layers. • Profile workloads across CPU, memory, I/O, network, and accelerator (GPU/NPU) subsystems to identify bottlenecks and optimization opportunities. • Establish and own performance baselines across CIQ's product and solutions portfolio. • Build and maintain automated performance regression-detection pipelines integrated into CI/CD workflows using Fuzzball. • Collaborate across engineering teams to root-cause regressions introduced by upstream kernel changes, compiler updates, or library modifications. • Drive proactive performance improvements across every layer of the stack. • Optimize for AI inference and training workloads, HPC workloads, and general computing and service workloads.

🎯 Exigences

• A deep, principled understanding of operating system internals - Linux kernel scheduler, memory subsystem, I/O stack, and networking. • Proven experience identifying and resolving performance regressions across kernel and user space in production environments. • Hands-on expertise with profiling and tracing tools: perf, eBPF/bpftrace, Flamegraphs, VTune, Nsight, strace, ftrace, and similar. • Strong background in AI/ML workload performance - including inference optimization (TensorRT, ONNX, vLLM, or similar), training efficiency, and GPU/accelerator utilization. • Experience with HPC workloads: MPI, OpenMP, parallel filesystems, RDMA/InfiniBand, and job schedulers (Slurm, PBS, etc.). • Familiarity with modern AI-first development workflows and comfort using LLM-based tools to accelerate engineering work. • Experience building automated performance testing and regression detection pipelines in CI/CD environments. • Excellent analytical skills - able to form hypotheses, design experiments, and draw actionable conclusions from complex data. • Strong written and verbal communication skills; able to present findings to both deeply technical audiences and business stakeholders. • A collaborative, humble, and always-learning mindset - combined with the confidence to champion performance as a first-class engineering concern.

🏖️ Avantages

• Medical, dental, and vision insurance. • Flexible paid time off. • Employee stock options. • Remote work; no travel required for most positions.
