About this role

Tenstorrent is hiring a Datacenter Liquid Cooling Architect to define and build advanced liquid cooling infrastructure for large-scale AI training and inference clusters. This on-site position is located in Toronto, Ontario, Canada, and is ideal for an experienced thermal design professional looking to shape mission-critical datacenter operations.

Role Overview

As a Datacenter Liquid Cooling Architect, the professional takes charge of defining, designing, and architecting next-generation liquid cooling systems for Tenstorrent's AI training and inference clusters. The role involves partnering closely with systems engineering, mechanical engineering, software, and cross-functional design teams. Responsibilities include building chassis-, rack-, and cluster-scale cooling solutions that incorporate coolant distribution unit (CDU) integration, telemetry, control mechanisms, leak detection, and resilient operating strategies to support internal and external customers.

Key Responsibilities

Design and architect next-generation liquid cooling infrastructure for chassis, rack, and cluster scales.
Partner with cross-functional groups including mechanical, systems, and software engineering.
Integrate commercial CDUs with telemetry, monitoring, and control systems.
Develop operational rules, failure-response procedures, and leak-detection and mitigation strategies.
Shape reliable AI datacenter architectures and deployments for internal and external customers.

Requirements

Ten or more years of experience as a datacenter and system thermal design professional architecting cooling infrastructure for complex computing environments.
Proven experience designing and operating single-phase liquid cooling systems, including fluid selection, glycol-water mixtures, dielectric fluids, corrosion inhibitors, material compatibility, and dry-break couplings.
Strong expertise in pressure-testing protocols, fluid dynamics, filtration, redundancy, and resilient cooling architectures.
Practical experience integrating flow, temperature, and pressure sensors with monitoring and control systems.
Strong knowledge of ASHRAE thermal guidelines, liquid-cooled IT environments, and facility HVAC integration.
