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
