后端工程师 - GPU性能
Lead Software Systems Engineer - GPU Performance
关于Nebius：
Nebius正在引领全球AI经济的云基础设施新纪元。我们正在构建一个全栈式AI云平台，支持开发者和企业从数据和模型训练到生产部署的全流程，而无需承担构建大型内部AI/ML基础设施的成本和复杂性。
由工程师打造，面向工程师。从大规模GPU编排到推理优化，我们在计算、存储、网络和应用AI领域掌握着最困难的问题。
在纳斯达克上市（NBIS），总部位于阿姆斯特丹，我们在欧洲、英国、北美和以色列设有研发中心，拥有全球化的业务布局。我们的团队超过1500人，包括数百名在硬件、软件和AI研发方面具有深厚专业知识的工程师。
我们正在寻找一位高级软件系统工程师 - GPU性能，将在构建我们的超大规模平台中发挥关键作用，跨核心组件工作，同时分析和优化硬件与软件交集处的大规模GPU集群的性能。
你将涉及整个技术栈——从硬件和系统软件到网络（InfiniBand/RoCE）、虚拟化（KVM/QEMU）以及分布式通信层（如MPI、NCCL）。
在此职位中，你将：
- 聚焦于理解多层系统行为，识别性能瓶颈，并推动改进，从而影响我们的集群是如何构建、运行、调优和验证的。
- 研究并排查GPU集群在真实工作负载（训练和推理）下的性能问题。
- 通过软件堆栈评估和集成新的硬件、系统配置和调优方法。
- 支持来自内部团队和客户的复杂性能相关升级问题。
- 与基础设施、软件工程和硬件供应商团队（如NVIDIA、Mellanox、Intel）紧密合作。
- 参与硬件和集群验收（资格认证），确保系统满足性能预期。
我们期望你具备：
- 5年以上系统级软件开发经验（专注于性能优化和底层编程）。
- 3年以上Linux系统的实际操作经验（管理、故障排除和性能调优）。
- 对服务器架构有深入理解，包括PCIe设备、网卡、Linux操作系统/内核以及高性能计算（HPC）系统。
- 精通一种或多种面向性能的编程语言（C/C++、Go、Python等）。

About Nebius:
Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.
Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.
Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.
We are looking for a Lead Software Systems Engineer - GPU Performance to play a key role in building our hyperscaler platform, working across its core components while analyzing and optimizing the performance of large-scale GPU clusters at the intersection of hardware and software.
You will operate across the full stack—from hardware and system software to networking (InfiniBand/RoCE), virtualization (KVM/QEMU), and distributed communication layers (e.g., MPI, NCCL).
In this role you will
- Focus on understanding system behavior across multiple layers, identifying performance bottlenecks, and driving improvements that shape how our clusters are built, operated, tuned, and validated.
- Investigate and troubleshoot performance issues of GPU cluster under real workloads (training and inference)
- Evaluate and integrate new hardware, system configurations and tuning approaches through software stack
- Support complex performance-related escalations from internal teams and customers
- Work closely with infrastructure, software engineering and hardware vendor teams (e.g. NVIDIA, Mellanox, Intel)
- Contribute to hardware and cluster qualification (acceptance), ensuring systems meet performance expectations
We expect you to have:
- 5+ years of professional experience in system-level software development (focused on performance optimization, low-level programming).
- 3+ years of hands-on experience with Linux systems (administration, troubleshooting, and performance tuning).
- In-depth understanding of server architecture, including PCIe devices, NICs, Linux OS/Kernel, and high-performance computing (HPC) systems.
- Strong proficiency in one or more performance-oriented programming languages (C/C++, Go, Python).
We conduct coding interviews as part of the process.
Key employee benefits:
- Health insurance: 100% company-paid medical, dental and vision coverage for employees and families.
- 401(k) plan: Up to 4% company match with immediate vesting.
- Parental leave: 20 weeks paid for primary caregivers, 12 weeks for secondary caregivers.
- Remote work reimbursement: Up to $85/month for mobile and internet.
- Disability & life insurance: Company-paid short-term, long-term and life insurance coverage.
