Technologist Mechanical Engineering

WD is building the infrastructure behind the AI-driven data economy.

As AI scales, so does data. Every interaction, every model, every system generates data that must be stored, managed, and made accessible over time. That’s where we come in.

We combine deep engineering expertise with global-scale manufacturing to deliver the storage systems that make AI possible, powering hyperscale data centers, cloud platforms, and enterprise infrastructure worldwide.

This isn’t theoretical work. It’s real systems, at real scale, people solving some of the hardest challenges in technology today.

We’re looking for people who want to build, solve, and operate at that level.

Join us and let’s shape the future of data.

Job Description
Western Digital is seeking a Mechanical Engineer with a minimum of 5 years of experience to design, develop, and validate mechanical components and assemblies for our Hard Disk Drive (HDD) product portfolio and data storage solutions. The engineer in this position will drive precision mechanical design for head-disk assemblies (HDA), actuators, base castings, and enclosures while meeting stringent performance and reliability requirements.

ESSENTIAL DUTIES AND RESPONSIBILITIES

• HDD-Specific Design & Development
  • Design precision mechanical components for HDD systems:
  • Head Stack Assembly (HSA) including actuators, flex circuits, voice coil motors
  • Base casting and top cover assemblies
  • Spindle motor integration and mounting systems
  • Shock dampening and vibration isolation structures
  • Breather filters and contamination control features
  • Develop parts using advanced CAD (Solid Works/NX) with tight tolerances
• Use geometric dimensioning and tolerancing (GD&T) for drawings and 3D models to communicate ideal part with allowable variation to meet functional requirements.
• Design for ultra-clean operation environments (Class 10/100 cleanroom)
• Use 3D printing and other rapid prototyping processes to conduct design validation testing.

Analysis & Simulation:

• Perform FEA on structural components (shock resistance, stiffness optimization)
• Conduct modal analysis for resonance avoidance in actuator systems
• Execute tolerance stack-up analysis for critical assemblies

Testing & Validation:

• Design test fixtures and develop test protocols for design validation.
• Execute environmental testing for shock, vibration, and thermal cycling
• Drive failure mode analysis and implement corrective actions (FMEA, root cause analysis)

Cross-Functional Collaboration:

• Partner with recording heads, media, firmware, and servo teams for system integration.
• Interface with suppliers on specifications and quality.
