Senior Hardware Systems Engineer

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 This Role: We are seeking a Hardware Production / Sustaining Engineer to strengthen Crusoe’s Hardware Systems Engineering team and close critical skill gaps in debugging, validation, and production support of high-performance compute systems. In this role, you will take ownership of the full hardware lifecycle—from prototype bring-up to large-scale production—while driving automation, deep issue resolution, and reliability across Crusoe Cloud’s GPU- and CPU-based infrastructure. You will work closely with cross-functional teams to support, debug, and improve hardware platforms at scale, with a particular focus on PCIe, InfiniBand, and NVMe/storage, which have been identified as essential areas for deeper expertise. Your work will directly impact Crusoe’s ability to deploy and operate sustainable, AI-first compute systems with world-class performance and reliability. What You’ll Be Working On: - Drive the full hardware development and sustaining lifecycle, including feasibility, bring-up, validation, deployment, and ongoing production support. - Develop and maintain scripting and automation frameworks for hardware testing, diagnostics, and continuous reliability improvements. - Lead deep troubleshooting and debugging across: - PCIe (link training, topology, performance issues) - InfiniBand (fabric debugging, throughput, connectivity issues) - NVMe/storage (performance bottlenecks, firmware interactions, failure analysis) - Conduct rigorous system validation and characterization for GPU, CPU, and high-performance compute platforms. - Support E2E integration and solution testing to ensure Crusoe Cloud products meet performance, reliability, and scalability expectations. - Collaborate with mechanical, thermal, firmware, software, and manufacturing teams to resolve system-level issues and enable stable production operation. - Drive prototyping, qualification, and readiness for high-volume manufacturing with both internal teams and external vendors. - Identify opportunities for new hardware technologies, testing methods, and sustainability improvements aligned with Crusoe’s long-term objectives. - Provide data-driven insights to influence Crusoe’s hardware roadmap and reliability strategy. What You’ll Bring to the Team: - 8–10+ years of experience in hardware development, validation, sustaining engineering, or production engineering. - Strong hands-on expertise in PCIe, InfiniBand, and NVMe/storage debugging and development. - Deep proficiency in hardware bring-up, board-level debugging, and system-level validation. - Ability to design and implement automation frameworks for hardware testing (Python, Shell, or similar). - Technical background in digital and analog design, server architecture, and high-performance compute hardware. - Experience working across thermal, mechani
