> Senior Hardware Systems Engineer driving full lifecycle of next-gen GPU/CPU compute platforms for AI workloads at Crusoe. Responsibilities include performance characterization, workload optimization, system debugging, and cross-team collaboration to maximize efficiency and reliability of large-scale AI infrastructure.

## Job Description

## What You’ll Be Working On
- Drive the end-to-end lifecycle of next-generation compute platforms, including evaluation, bring-up, validation, deployment, and production readiness.
- Define and execute performance characterization and validation strategies for CPU, GPU, and accelerated computing platforms.
- Conduct in-depth workload characterization studies across training and inference - dense, MoE, long-context, and multimodal models to understand compute, memory, communication, and I/O behavior on target platforms.
- Translate workload and platform insights into cluster-level tuning and configuration recommendations: topology, parallelism strategy, scheduling, power, and software stack settings to maximize delivered performance and efficiency.
- Build and maintain workload performance profiles and reference configurations that guide how clusters are deployed, tuned, and scaled for specific model families and workload classes.
- Analyze system and workload performance, identify bottlenecks, and work across hardware and software layers to drive improvements.
- Lead complex system-level debugging across compute, memory, storage, networking, accelerators, and platform firmware.
- Partner with vendors and internal engineering teams on prototyping, qualification, NPI, and production readiness of new technologies.
- Collaborate across hardware, firmware, networking, software, infrastructure, reliability, and operations teams to resolve complex platform issues.
- Use data and system-level insights to influence platform architecture, technology selection, hardware roadmaps, and long-term infrastructure strategy.

## What You’ll Bring to the Team
- 5-6+ years of experience in hardware systems engineering, platform engineering, performance engineering, ML systems engineering, infrastructure engineering, or related areas.
- Hands-on experience with large-scale GPU or accelerated computing infrastructure for AI/ML or HPC workloads.
- Hands-on experience with distributed training and/or inference workloads at scale, including parallelism strategies and performance tuning across the hardware/software stack.
- Experience with workload benchmarking, performance profiling, and system performance optimization across hardware and software layers.
- Strong understanding of modern server and accelerator architectures, including CPU, GPU, memory, storage, networking, and high-speed interconnects such as PCIe, InfiniBand, or NVLink.
- Hands-on experience with system bring-up, validation, performance characterization, and root-cause analysis of complex hardware/software issues.
- Experience developing automation, testing, diagnostics, or data-analysis frameworks using Python, Shell, or similar languages.
- Ability to analyze system behavior using telemetry, benchmarks, profiling tools, and other quantitative data.
- Experience working across multiple engineering disciplines, including hardware, firmware, software, networking, and infrastructure teams.
- Strong analytical and problem-solving skills with the ability to operate effectively in ambiguous and rapidly evolving environments.
- Excellent technical communication skills and experience collaborating with internal engineering teams, customers, and external technology partners.
- Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.

## Bonus Points
- Experience influencing hardware or system configuration decisions based on workload performance data (e.g: HW/SW co-design, platform tuning studies).
- Deep experience with RDMA, RoCE, CXL, NVLink or fabric-level performance analysis.
- Experience with inference serving frameworks, training frameworks, or ML compiler/runtime stacks.
- Familiarity with both x86 and ARM-based server platforms.
- Experience building observability, diagnostics, or fleet-level performance and reliability systems.
- Experience introducing new compute technologies into production cloud or large-scale datacenter environments.
- Understanding of infrastructure efficiency, power, cooling, performance-per-dollar, or total cost of ownership considerations.
- Background in sustainable or energy-efficient hardware design practices.
- Advanced certifications or coursework in AI/HPC hardware systems.
