Advanced Systems Engineering Director

Systems Design & Architecture • Lead end-to-end mechanical and electrical design of modular data center systems, including structural enclosures, power distribution, cooling infrastructure, and IT hardware integration • Define system architecture trade-offs across density, thermal performance, reliability, and cost • Develop and own detailed design specifications, BOMs, and engineering drawings IT Hardware Integration • Architect rack-level and pod-level IT layouts for high-density GPU and CPU compute deployments • Specify and validate server, networking, storage, and power hardware configurations in collaboration with hyperscale and neocloud customers • Ensure designs meet evolving requirements for AI/ML workloads, including high power density (40–100+ kW per rack) and advanced cooling compatibility (liquid, immersion, rear-door) Thermal & Power Modeling • Build and validate CFD and thermal models to predict and optimize airflow, cooling performance, and PUE across a range of operating conditions • Develop power distribution models covering UPS, PDU, busway, and generator integration • Use simulation tools to iterate designs rapidly before physical prototyping Manufacturing & Productization • Partner with internal and contract manufacturers and suppliers to translate designs into manufacturable, scalable products • Define DFM (Design for Manufacturability) and DFA (Design for Assembly) requirements • Lead design reviews, tolerance analyses, and factory acceptance testing protocols • Manage engineering change processes and maintain design documentation through the product lifecycle Cross-Functional Leadership • Collaborate with energy, controls, and software teams to integrate data center systems with Exowatt's P3 solar and storage platform • Serve as a technical lead and mentor to junior engineers on the team • Engage directly with customers and partners on design requirements, site adaptations, and deployment planning

Required Qualifications • 7+ years of engineering experience, with at least 4 years focused on manufacturing, design, and/or mission-critical infrastructure • Deep expertise in at least two of the following: mechanical/structural systems, power distribution, thermal management, or IT hardware architecture • Hands-on experience with thermal or power modeling tools (e.g., 6SigmaRoom, FloEFD, ANSYS, or equivalent) • Experience taking designs from concept through manufacturing and deployment • Excellent technical communication skills — able to write crisp specs, lead reviews, and explain trade-offs clearly Preferred Qualifications • Experience with modular or prefabricated products at large scale • Familiarity with high-density liquid cooling architectures (direct liquid cooling, rear-door heat exchangers, immersion) • Background working with hyperscale, colocation, or neocloud customers • Exposure to renewable energy integration or microgrid/behind-the-meter power systems • Strong working knowledge of data center standards (TIA-942, ASHRAE, Uptime Institute tier classifications) • Product lifecycle management (PLM) expertise • 2+ years of experience with Nvidia and other compute platforms • Experience in a fast-paced startup or hardware product company
