About the role

Mechanical Design Engineer focused on sustaining engineering for Meta's humanoid robot hardware, acting as the primary contact for failure investigation, corrective design actions, and design-for-manufacture improvements based on real-world feedback from fabrication and assembly teams. Hands-on role at the design office and shop floor boundary, collaborating with cross-functional teams to deliver complete hardware solutions and improve build efficiency.

Responsibilities

  • Lead root-cause analysis (RCA) on mechanical failures — fractured components, worn interfaces, fatigue cracks, fastener loosening, tolerance stack-up issues
  • Own the corrective action process: document failure mode, determine root cause, implement and verify design fix, and update drawings and specifications
  • Maintain a failure tracking database; identify recurring failure patterns and drive systemic design improvements
  • Collaborate with test and reliability engineers to correlate field/lab failures back to design margins and loading assumptions
  • Initiate and manage Engineering Change Orders (ECOs) to implement corrective actions into production documentation
  • Serve as the primary design engineering liaison to the assembly and integration team
  • Collect, triage, and action assembly feedback — difficult-to-reach fasteners, unclear build sequences, interference issues, tooling access constraints, and handling concerns
  • Implement design changes that reduce assembly time, lower operator skill requirements, and improve build repeatability
  • Develop and revise assembly work instructions, torque specifications, and inspection criteria based on build technician input
  • Participate in hands-on build activities to first-hand identify ergonomic and process pain points
  • Design tooling to facilitate complex component assembly
  • Maintain and improve the sustaining engineering change process — from issue identification through design release and verification
  • Support configuration management and BOM accuracy for all active robot builds
  • Track and report sustaining metrics: open issues, mean time to corrective action, repeat failure rate, assembly hours per unit
  • Develop and document standard work instructions and assembly aids for prototype and production builds
  • Work closely with a cross-functional team of engineers (Electrical, Software, Firmware) to deliver complete technical solutions
  • Troubleshoot root-cause of mechanical failures, implement improved designs, and test effectiveness of changes

Qualifications

  • BS degree in Mechanical Engineering
  • 7+ years of experience in Mechanical Design Engineering with a meaningful portion in sustaining, production, or manufacturing engineering
  • Strong CAD proficiency (SolidWorks, NX, or CREO) including full drawing packages with GD&T per ASME Y14.5
  • Working knowledge of CNC machining processes — understanding of fixturing, tool access, setup minimization, and achievable tolerances
  • Experience interpreting assembly feedback and translating it into actionable design improvements
  • Hands-on experience working on a shop floor or in a build area
  • Familiarity with engineering change management processes (ECO/ECN/ECR workflows)
  • Experience with rapid prototyping manufacturing processes and materials
  • Experience managing time-sensitive projects through to completion while balancing evolving priorities and a broad range of stakeholders
  • Experience in tolerance analysis and geometric dimensioning and tolerancing (GD&T per ASME Y14.5)
  • Experience in Finite Element Analysis (FEA)
  • Experience with tolerance analysis tools and methodologies (RSS, Monte Carlo, worst-case)
  • Familiarity with common joining and fastening methods and their trade-offs in robotic assemblies
  • Experience communicating technical recommendations and influencing design decisions across multidisciplinary teams (e.g., failure reports, design reviews, ECO proposals)
  • Experience with lightweighting strategies (topology optimization, lattice structures, composite materials)
  • Background in high-mix/low-volume transitioning to mid-volume production environments
