Principal Hardware Product Manager - Spark

About this role

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.

We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI.

We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.

If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.

About the role:

Crusoe is a vertically integrated AI Factory company accelerating the abundance of energy and intelligence through modular infrastructure. We are seeking a Principal Hardware Product Manager to own the multi-year Hardware roadmap and Product Requirement Documents (PRDs) for Crusoe Spark™, our modular datacenter.

In this role, “hardware” and “product” refers to the physical infrastructure of the Spark module: structural steel modules, RPPs, DLC cooling loops, CDUs, chillers, piping headers, electrical and mechanical systems, and power distribution gear. Compute hardware (servers, GPUs, storage, networking, and rack specifications) is owned by Cloud Product. Cloud Product defines the compute needs; you define the Hardware that houses and powers it.

What You'll Be Working On:

I. Physical Module Roadmap & Design Requirements

- Hardware Roadmap Ownership: Own and maintain the multi-year Spark hardware roadmap.

- Hardware PRD Authorship: Author precise Spark PRDs for physical modules, translating compute needs into concrete structural, thermal, and electrical specifications.

- Compute-to-Hardware Translation: Receive Cloud Product’s GPU, server, and rack requirements and translate them into modular physical configurations - power envelopes/distribution, rack weights, fluid specs. Partner with Cloud Product leads and own the facility-side interface: power distribution to racks, fluid flow, rack weight and floor loadings etc.

- Physical Version Management: Manage hardware generation transitions. Define cut-in criteria, retrofit rules, module-side accommodation of rack footprint, loading, and cooling interface per Cloud Product’s rack specifications., and documentation required for manufacturing release.

II. Requirements Ownership & Engineering Partnership

- Spark Hardware TPM Alignment: Work in lockstep with Spark Hardware TPMs and engineering discipline leads (Mechanical, Electrical, Structural, Thermal) to guide physical development from concept to build.

- Requirements Discipline: Set clear product hardware requirements (module power distribution capacity, thermal capacity, transportability) and hold hardware engineering teams accountable without prescribing detailed sub-component implementation.

- Design Partner Leadership: Serve as the primary design contact for external architecture, engineering, and modular design firms.

- Requirements intake from Cloud Product: Collaborate with Cloud Product teams to ensure that the physical Spark module hardware supports the GPU & rack-level architecture needs. Translate GPU/rack compute needs directly into physical facility capabilities (fluid flow rates, power specs, structural building and frame requirements).

What You'll Bring to the Team:

- Physical Infrastructure Roadmap Expertise: 10-15 years owning multi-year physical product roadmaps, with a proven track record shipping complex hardware or heavy mechanical/electrical infrastructure.

- Disciplined Hardware PRD Management: Expertise in writing clear hardware product requirements (PRDs) for physical systems and requisite sub-systems separating product requirements from engineering requirements, and designing to requirements supplied by an upstream customer or platform team.

- Cross-Functional Leadership: Track record driving alignment across mechanical, electrical, structural, thermal, and manufacturing teams during first-of-a-kind builds.

- Clear Technical Communication: Exceptional written communication with emphasis on precise engineering trade-off documentation and executive-level clarity.

Education

- Required: Bachelor’s degree in Electrical, Mechanical, Systems, or a related physical engineering discipline.

- Strongly Preferred: Master’s degree in Engineering (Mechanical or Electrical) and/or an active Professional Engineer (PE) license in at least one U.S. jurisdiction.

Bonus Points

- DLC & Advanced Thermal Design: Experience specifying liquid cooling loops, CDUs, or secondary fluid loops for high-density compute environments.

- Data Center Infrastructure: Product experience in physical data center infrastructure, high-voltage distribution, industrial cooling, or heavy modular/prefab hardware.

- Advanced Power Distribution: Experience specifying 800V DC or medium-to-low voltage data center power topologies.

- Modular Construction / Offsite Fabrication: Hands-on experience with modular/prefab construction, containerized enclosures, or advanced offsite manufacturing.

- Tooling Fluency: Familiarity with CAD/BIM platforms (Revit, SolidWorks), electrical single-line diagrams (SLDs), or CFD/thermal simulation workflows.

This Role Is Not a Good Fit If:

- You’ve owned physical infrastructure products end to end: You have defined, built, and shipped…
