Platform Technical Project Manager, Rack-Scale AI Sysytems

What MatX Is Building

MatX is on a mission to be the compute platform for AGI. We are developing vertically integrated full-stack solutions from silicon to systems including hardware and software to train and run the largest ML workloads for AGI. MatX is seeking silicon micro-architects and design engineers to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management.

High-speed connectivity and other key technologies.

About the Role

MatX is building next-generation AI infrastructure systems for high-performance datacenter workloads. We are looking for a Senior Platform TPM, Rack-Scale AI Systems to drive design-phase execution for our rack-scale platform. This role will coordinate cross-functional execution across rack architecture, accelerator board design, power delivery, thermal and liquid cooling, high-speed interconnect, firmware, diagnostics, test vehicles, system validation, and external CM/JDM partner engagement.

You will work closely with Systems Engineering, hardware engineering, firmware, validation, supply chain, and external CM/JDM partners.

What You'll Do Here

* Drive the integrated execution plan for rack and board design from architecture through design release.

* Own and maintain the design-phase master schedule across rack, board, power, thermal, interconnect, mechanical, firmware, diagnostics, validation, and supply-chain dependencies.

* Coordinate execution across key platform work streams, including board electrical/SI/PI readiness, rack power, liquid cooling, cable/optical interconnect, BMC/telemetry, diagnostics, test vehicles, PLM/BOM/ECO readiness, and external CM/JDM design reviews.

* Partner with Systems Engineering to define design gates, risks, dependencies, decision points, and exit criteria.

* Track critical path items, schedule risks, owners, closure dates, and escalation paths.

* Coordinate design-readiness reviews, DFX reviews, and implementation-readiness reviews with internal teams and external CM/JDM partners.

* Drive readiness for system validation using test vehicles, including power, thermal, connectivity, diagnostics, instrumentation, telemetry, and validation planning.

* Maintain a live risk register covering design readiness, system validation readiness, power/thermal risks, interconnect risks, long-lead dependencies, and supply-chain risks.

* Ensure long-lead design dependencies are visible to supply chain, materials, and sourcing teams.

* Prepare executive-level updates covering milestone health, top risks, decisions needed, critical path, and resource gaps.

* Ensure validation learnings are captured, tracked, and incorporated into the platform execution plan.

Who you are

* 8+ years of technical program management, hardware engineering program management, systems engineering, or hardware platform development experience.

* Experience managing complex hardware platforms through architecture, design, validation, and design release.

* Experience working across electrical, mechanical, thermal, firmware, validation, manufacturing, supply-chain, and external partner teams.

* Ability to drive schedules, dependency management, issue tracking, risk management, milestone governance, and executive-level communication.

* Experience coordinating design reviews and driving closure across cross-functional engineering teams.

* Working familiarity with several of the following areas: board design, power delivery, SI/PI, thermal design, liquid cooling, high-speed interconnect, firmware, diagnostics, rack integration, or system validation.

* Experience working with ODMs, JDMs, contract manufacturers, or external engineering/manufacturing partners.

* Strong written and verbal communication skills, including the ability to summarize technical risks, tradeoffs, decisions, and schedule impact.

* Proficiency with program-management and engineering collaboration tools such as Jira, Confluence, Smartsheet, MS Project, Google Workspace, or equivalent.
