[OpenNash Jobs](https://jobs.opennash.com/) / [Meta Platforms](https://jobs.opennash.com/companies/meta-platforms/) / Manufacturing Design Engineer - Mechanical

## Job description

The Manufacturing Design Engineering (MDE) Team evaluates advanced manufacturing technologies and identifies scalable supply chain and process solutions that allow Technical Operations to bring next-generation consumer hardware products to market. We are seeking a Mechanical Manufacturing Design Engineer (MDE) with deep technical expertise in Tier-II mechanical secondary operations, surface finishing, and assembly processes.

In this role, you will bridge the gap between engineering design (PD/ID) and volume operations, defining scalable process flows, qualifying fixtures and automation, and driving supplier technical execution from early NPI prototyping through mass production. The ideal candidate possesses demonstrated hands-on process engineering capability, understands the physics of materials and secondary operations, and can independently influence cross-functional decisions to balance design intent, cosmetic quality, high yields, and cost-effectiveness.

## Responsibilities

### XFN Collaboration with Hardware Engineering (PD / ID)
- Serve as the primary manufacturing operations DRI for Tier-II secondary processes (post-forming/post-molding), guiding equipment selection, material compatibility, process parameters, and qualification frameworks to ensure cost-effective, high-volume manufacturability
- Evaluate critical part geometries, review vendor DFM, and recommend specification/tolerance adjustments to improve process capability ($C\_p / C\_{pk}$) and yield
- Lead exploration and benchmarking of novel secondary manufacturing and surface-finishing technologies during early NPI phases Secondary
- Process and Operational Ownership: Define and drive end-to-end secondary process flows, including precision CNC machining, bonding/dispensing, welding, heat staking, lamination, and cosmetic surface finishing (PVD, anodizing, painting, coating, polishing)
- Review, qualify, and optimize assembly and machining fixtures, inspection nests, and semi-automated/automated secondary equipment at supplier sites
- Establish and maintain the Manufacturing & In-Process Plan (MIP) with Tier-II suppliers across all build milestones (Proto/EVT/DVT/PVT/MP)
- Partner with SQE, Tooling, and ID to align on cosmetic and dimensional boundary samples, inspection protocols, and visual/functional yield ramp standards Commercial & Operational Strategy: Partner with Global Supply Management (GSM) to evaluate and select Tier-II manufacturing partners across APAC, assessing supplier technical competence, equipment capability, and line readiness
- Build technical proposals during conceptual NPI stages, providing process flow architecture, cycle-time modeling, throughput calculations, and cost-of-manufacturing analyses
- Present technical feasibility, operational trade-offs, and readiness roadmaps at core team reviews to secure cross-functional and executive alignment Supplier Capability & Lean Manufacturing: Drive suppliers to implement Lean manufacturing principles, optimize their tact and cycle time, reduce line touchpoints, and implement robust in-line process controls
- Design and execute structured
- Design of Experiments (DOEs) to systematically address root causes, resolve yield bottlenecks, and elevate supplier process maturity prior to ramp

## Qualifications

### Education

Bachelor’s or Master’s degree in Mechanical Engineering, Manufacturing Engineering, Materials Science, or a related discipline Experience: 5+ years of hands-on experience in mechanical manufacturing process engineering, NPI bring-up, and technical problem-solving within the consumer electronics or precision hardware industry Secondary Process Mastery: Deep technical and hands-on experience across multiple mechanical secondary operations: Machining & Fabrication: Precision CNC machining (fixtures, cutter pathing/tooling) selection, multi-axis machining); Joining & Assembly: Ultrasonic welding, laser welding, structural adhesives, glue dispensing, and heat staking; Surface

Finishing & Treatment: Anodization, PVD, painting/spray coating, pad printing, sandblasting, and precision polishing; Converting & Softgoods/Films: Die-cutting, PSA lamination, fabric wrapping, and thermoforming Fixture & Automation Understanding: Hands-on experience developing and qualifying precision fixtures, vacuum nests, and automated/semi-automated stations for small mechanical parts and sub-assemblies Statistical & Quality Engineering: Experience applying statistical process control methods; proficient in using JMP, Minitab, or

Python/Excel to analyze DOE data, FAI, and SPC/Cpk metrics Vendor Management: Proven track record of managing and technical-coaching Tier II hardware suppliers in APAC regions Communication & Location: Fluent in written and verbal English and Mandarin, as the role requires direct technical coaching and daily communication with Tier-II suppliers in

Mainland China; with the ability to travel frequently to supplier sites Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)

### Advanced Material & Structural Joining

Experience with specialized structural bonding, micro-screwing, thermal staking, ultrasonic/laser welding, and automated glue dispensing across mixed materials (metals, engineered plastics, and softgoods) Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)

### DFX / DFA Mastery

Experience conducting
- Design for Assembly (DFA) and Design for Manufacturing (DFM) reviews with Product Design (PD) early in NPI—identifying assembly interferences, optimizing datum schemes, simplifying part stacking, and minimizing manual assembly steps
- Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies Precision Small-Part Automation & Fixturing: Proven track record in designing, qualifying, and scaling high-precision automated assembly stations, robotic pick-and-place, vision-guided alignment, and custom assembly nests for micro/miniature components Assembly
- Process Development: Extensive experience in assembly line bring-up, line balancing, and mass production ramp for high-volume consumer electronics or wearable devices Critical Module Integration: Hands-on experience developing assembly and calibration processes for sensitive modules such as camera, audio, display, optical-mechanical, and sensor sub-assemblies Lean Assembly Line Design: Practical background in takt time optimization, operator ergonomics, poka-yoke (error-proofing) mechanism design, and Six Sigma/Lean manufacturing methodologies to eliminate bottlenecks and minimize scrap
