About the role
Staff HPC Systems Architect information for Lambda’s AI cloud infrastructure, focusing on scalable compute platforms for AI/ML, simulations, and high-throughput workloads.
Responsibilities
- Architect and define scalable compute platforms optimized for AI/ML, simulation, and high-throughput workloads.
- Develop compute system standards and design patterns to ensure consistency, performance, and maintainability across infrastructure.
- Evaluate emerging CPU, GPU, and accelerator technologies, owning architectural tradeoff decisions that impact compute density, power, cooling, and total cost.
- Collaborate with product and engineering teams to map workload requirements to compute platform capabilities across bare metal and cloud deployments.
- Convert ambiguous business or customer needs into measurable platform requirements, technical specifications, acceptance criteria, and architecture decisions.
- Define compute platform roadmaps and architectural reference designs that guide hardware selection, firmware baselines, rack-level, and cluster design.
- Act as a technical lead during new platform introductions, guiding validation and performance characterization efforts.
- Mentor systems engineers and cross-functional stakeholders on compute performance tuning, sizing, and architectural decisions.
Qualifications
- Proven experience (7+ years) architecting large-scale 10k-100k+ GPU HPC or cloud compute platforms.
- Deep knowledge of CPU/GPU architectures, memory hierarchies, and accelerator topologies.
- Experience designing systems around high-bandwidth, low-latency fabrics (NVLink, InfiniBand, and RoCE).
- Strong understanding of system performance tuning, resource scheduling, thermal and power optimization, and compute lifecycle management.
- Comfortable working across hardware and software boundaries, especially at the intersection of compute architecture, OS behavior, and orchestration layers.
- Skilled at balancing architectural tradeoffs for density, power efficiency, cooling, and performance.
- Strong analytical and communication skills, with a track record of influencing technical strategy across teams.
- Strong ownership and can-do attitude, self-starter who feels comfortable working in ambiguity.
