Architecture / architect

OpenAI's Hardware organization develops system and infrastructure solutions tailored to the demands of advanced AI workloads. We work across the full stack—from silicon to system integration—partnering closely with internal teams and external vendors to define and deliver next‑generation AI infrastructure.

Our team focuses on defining scalable, high-performance system architectures and reference designs that balance performance, cost, and operational efficiency across rapidly evolving technologies.

We are seeking a 3P Architect to define and drive rack‑ and cluster‑level reference designs in collaboration with external partners. This role is responsible for translating workload requirements and system‑level goals into concrete architectures, aligning partners on critical design attributes, and ensuring vendor roadmaps meet our infrastructure needs.

You will work closely with performance modeling and internal architecture teams to evaluate tradeoffs, while owning the end‑to‑end definition and execution of third‑party system designs. We use a hybrid work model of 3 days in the office per week and offer relocation assistance.

Define rack‑ and cluster‑level reference architectures for AI infrastructure deployments.

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.

Define and lead proof‑of‑concept (PoC) efforts to validate new architectures and technologies.

Have strong experience in system architecture for large‑scale infrastructure or data center environments.

Are comfortable working with performance modeling outputs to inform architectural direction.

Have experience working with or managing hardware vendors (ODM/JDM, silicon, networking).

Familiarity with accelerators (GPUs/ASICs), interconnects, and data center networking architectures.

Background in infrastructure deployment, hardware engineering, or systems integration.
