Mechanical Design Engineer, Robotics Sustaining Engineering

At Meta, we're building the future of human connection and the technology that enables it. This means continuously inventing and developing technologies for the next generation of experiences.
To continue our efforts in the path to AGI, and as we move closer to a future with intelligent robots and advanced AI models, we're hiring talent across a broad range of disciplines from robotics hardware to system software, machine perception, and artificial intelligence. These crucial projects and initiatives taken on by this team have never been done before, so you have a rare opportunity to help us create new ways people connect around the world.
The Meta Robotics Hardware team is seeking a Mechanical Design Engineer focused on sustaining engineering to own the design health and continuous improvement of our humanoid robot hardware after initial release. You will be the primary engineering contact for failure investigation, corrective design action, and design-for-manufacture improvements driven by real-world feedback from our fabrication shops and assembly teams. This is a hands-on role that lives at the boundary between the design office and the shop floor — you'll spend as much time reviewing failed parts and assembly pain points as you do in CAD. This role will be part of a ME team responsible for concept development, analytical modeling, prototype design, first article build, fabrication, vendor management, and testing. Candidates should be comfortable working in a high ambiguity, fast paced environment where full system requirements are seldom known. This team is dedicated to building hardware that enables learning through data collection and system testing.
Mechanical Design Engineer, Robotics Sustaining Engineering 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

Minimum 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 (Solid Works, 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

Preferred Qualifications:

Exposure to Lean manufacturing principles or structured problem-solving methodologies (8D, A3, Ishikawa)
Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
Experience with additional manufacturing processes: sheet metal, additive manufacturing, anodizing, and plating
Ability to read and interpret FEA results to inform failure investigations and design margin assessments
Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
Direct experience with robotic systems — BLDC motors, actuators, gearboxes, linkage mechanisms
Experience writing clear failure reports that cross-functional teams can act on
Experience with PLM/PDM systems (Teamcenter, Solid Works PDM, Windchill, or similar)
Familiarity with statistical tolerance analysis and process capability (Cp/Cpk)
