3P Architect
Defines rack- and cluster-level reference architectures for AI infrastructure, translates workload requirements into designs, collaborates with partners and modeling teams to evaluate tradeoffs, and drives vendor roadmaps to address technology gaps.
Key Responsibilities
- Define rack- and cluster-level reference architectures for AI infrastructure deployments.
- Translate workload requirements into clear system design specifications and partner deliverables.
- Collaborate with performance modeling teams to evaluate architectural tradeoffs and system behaviors.
- Align internal stakeholders and external partners on critical system attributes (performance, cost, power, reliability, scalability).
- Identify gaps in current technology offerings and drive vendors (ODM/JDM, silicon, networking) to close those gaps.
- Influence and shape vendor roadmaps to meet future infrastructure needs.
- Track emerging technologies and evaluate their applicability to AI systems.
- Define and lead proof-of-concept (PoC) efforts to validate new architectures and technologies.
- Act as a key interface between OpenAI and external partners, ensuring execution against design intent.
Qualifications
- Strong experience in system architecture for large-scale infrastructure or data center environments.
- Understand AI workload characteristics and how they map to system-level design decisions.
- Comfortable working with performance modeling outputs to inform architectural direction.
- Experience working with or managing hardware vendors (ODM/JDM, silicon, networking).
- Can drive alignment across multiple stakeholders with competing constraints.
- Track record of turning ambiguous requirements into clear, executable system designs.
- Proactive in identifying gaps and driving solutions across organizational boundaries.
Preferred Skills
- Experience defining rack- or cluster-level systems for hyperscale or AI workloads.
- Familiarity with accelerators (GPUs/ASICs), interconnects, and data center networking architectures.
- Experience influencing vendor roadmaps and reference designs.
- Background in infrastructure deployment, hardware engineering, or systems integration.
- Experience leading PoCs or early-stage hardware validation efforts.
Staff Software Engineer, Infrastructure Asset Systems
As a Staff Software Engineer, you will build and extend systems for tracking, governing, and reporting on infrastructure assets. This involves designing data models, workflow engines, and integrations with financial and procurement systems, ensuring compliance and auditability.
Performance Engineer, Inference Systems
Performance engineer focused on cross-layer investigations of Anthropic's inference fleet for Claude, optimizing throughput, latency, reliability, and correctness while building observability and partnering with kernel and serving teams.
Tech Lead, Deployment & Operations — Custom Infrastructure
Lead deployment and operations for OpenAI’s custom silicon and systems into data center environments. Drive hardware bring-up, validation, production deployment, and fleet reliability at scale while leading a technical team.
Staff Fiber Network Engineer
Owns end-to-end physical layer of private global dark-fiber backbone network, including route design, fiber acquisition, vendor management, acceptance testing, and lifecycle management. Requires deep OSP/fiber expertise, optical transport knowledge, and 8+ years experience building fiber programs.
Software Engineer, Systems - Claude Code
Optimizes performance and reliability of Claude Code and Bun JavaScript runtime through low-level systems programming. Requires deep expertise in C/C++/Rust, syscalls, memory management, and runtime internals with 5+ years experience.
