Software engineer jobs in Austin, TX

About the role

We're looking for a Principal Engineer to join our CSP Engagements team as the technical focal point for end-to-end performance, working directly with engineering teams of key CSP/hyperscale customers to ensure they achieve various performance targets on NVIDIA platforms. In this role, you will augment NVIDIA's performance and benchmark teams with a dedicated CSP-facing focus. You will drive work streams with CSP engineering teams to build shared understanding of platform performance characteristics, gather and incorporate their workload-specific feedback into NVIDIA's optimization priorities, and validate that performance targets are met in customer-representative configurations.

What you'll bring

• 15+ years of experience in systems performance engineering
• BS or MS in Computer Science, Computer Engineering, or related field (or equivalent experience)
• Proficiency in GPU workload profiling: nsight systems, nsight compute, DCGM metrics, or equivalent instrumentation
• Understanding of distributed training performance dynamics: computation/communication overlap, pipeline bubbles, memory bandwidth utilization, collective efficiency
• Statistical methods for performance analysis: regression detection, confidence intervals, A/B comparison at scale
• Understanding of how the full software stack impacts performance: driver overhead, collective algorithm selection, memory allocation, scheduling, firmware power management
• Strong data analysis and visualization skills (Python, pandas, dashboards).
• Customer obsession — genuine passion for understanding why customers aren't achieving expected performance and driving solutions
• Ability to communicate performance findings to both deep technical audiences and executive leadership
• Demonstrated success influencing multiple engineering teams to prioritize performance improvements
• ideally in GPU/HPC/ML infrastructure.
