Mechanical Engineer III

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:

The Tooling & Fixture Engineer is a motivated, hands-on engineer responsible for designing and supporting production tooling and fixtures across Crusoe's modular data center and power distribution product lines. Reporting through the Manufacturing Engineering organization with a dotted-line connection to Design Engineering, this role bridges day-to-day production needs with upstream product design.

In this role, you will ensure that every assembly operation is backed by tooling that is safe, repeatable, and efficient. You will execute tooling projects with increasing independence, own fixture designs through their full lifecycle, and actively participate in DFM/DFMA reviews to enable Crusoe's rapid infrastructure scaling.

What You'll Be Working On:

• Fixture Design & Documentation: Design and detail jigs, fixtures, assembly aids, and test tooling for modular buildings and switch gear using Solid Works. Produce complete fabrication drawings, BOMs, and technical packages.
• DFM/DFMA Participation: Actively participate in Design for Manufacturability and Assembly reviews, providing practical engineering input on tooling complexity, accessibility, and cost.
• Tooling Qualification: Coordinate first-article inspections (FAI) of new and revised tooling with fabrication vendors. Document results and manage the disposition of any non-conformances.
• Work Instructions: Author and maintain clear, illustrated work instructions and tooling setup sheets for production technicians, ensuring documentation is synchronized with ECO-driven changes.
• Manufacturing Support: Provide hands-on support on the production floor to troubleshoot tooling fit and function issues. Implement quick-fix solutions and escalate systemic problems through root-cause analysis.
• Lifecycle Management: Maintain tooling revision history within Solid Works PDM. Execute engineering change orders affecting tooling and coordinate updates with Production Planning.
• Continuous Improvement: Identify opportunities to simplify or improve existing fixtures based on assembly feedback, yield metrics, or ergonomics concerns.
• Cross-Functional Collaboration: Partner directly with Design Engineers during development cycles to ensure tooling concepts are developed in parallel with product designs.

What You'll Bring to the Team:

• Education: Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or an equivalent discipline.
• Experience: 3-6 years of experience in fixture design, tooling engineering, or mechanical design within a manufacturing environment.
• Technical Proficiency: Proficient in Solid Works 3D modeling (including sheet metal and weldments) and drawing creation. Experience with Solid Works PDM is preferred.
• GD&T: Working knowledge of ASME Y14.5 sufficient to define fixture locating schemes and interpret part inspection reports.
• Fabrication Fundamentals: Practical understanding of machining, welding, and sheet metal fabrication; able to design buildable, cost-appropriate tooling.
• Detail Orientation: Meticulous commitment to drawing accuracy and documentation completeness to mitigate production risk.
• Physical Requirements: Ability to lift/move up to 50 lbs and stand/walk for extended periods on the production floor.
• Safety and Compliance: This position is designated a safety-sensitive position and/or is located in a safety-sensitive facility. Drug and alcohol program participation is required.

Bonus Points:

• Master's degree in Mechanical or Manufacturing Engineering.
• Experience designing tooling for sheet metal enclosures, structural weldments, or electrical switch gear.
• Exposure to Lean Manufacturing or error-proofing (poka-yoke) principles.
• Experience with ERP/MRP systems in a manufacturing context.
• Engineer in Training (EIT) credential or progress toward PE licensure.

Benefits:

• Competitive compensation and equity…
