Mechanical Engineer

Neybo is an AI companion device for children aged 4 to 8. Unimatch Lab is an AI-agent-run venture builder with seven products across Future of Work, Longevity, Kids Universe, and Education.

• Own the mechanical design of the plastic enclosure and internal frame, and support placement of PCBAs, cables, speaker, microphones, battery, and antennas
• Design buttons, sensors, and the charging port for children aged 4 to 8, ensuring resistance to jamming and rough use
• Support acoustic integration so the speaker chamber maintains clean sound through the shell while minimally affecting microphone voice capture
• Manage the thermal interface and heat dissipation from PCBAs to keep the outer shell safe for children’s hands
• Design early frames and enclosures for 3D printing and CNC to validate weight, mass distribution, and look and feel
• Support manufacturing early functional prototypes based on the available BOM and constraints
• Select enclosure materials that are safe for children to touch and chew, impact-resistant, and break into smooth, blunt pieces if cracked
• Design to ASTM F963 (US) and applicable UAE/GCC toy safety requirements from the start
• Eliminate pinch points, sharp edges, and choking hazards through upfront design decisions
• Support tolerance and snap-fit requirements and the injection molding development process run by the contract manufacturer (ODM)
• Audit and sign off on injection tooling and trial runs with the contract manufacturer
• Provide material and tooling cost/quality trade-offs for BOM decisions owned by the Hardware Tech Lead
• Evaluate factories and recommend one based on mechanical capacity, tooling quality, and reference projects
• Run the on-site NPI cycle — EVT, DVT, PVT, MP — including line audits, first article inspection, pilot run, and production launch
• Provide corrective feedback for production defects and conduct root cause analysis on the production floor
• Negotiate schedules, minimum order quantities, and technical trade-offs directly with the factory within the budget and timeline set by the Hardware Tech Lead
• Run drop, cyclic, thermal, aging, and structural tests; use FEA for critical mechanical parts before design freeze
• Work with the Hardware Tech Lead to keep the enclosure compatible with antenna, PCBA, and speaker placement
• Develop test requirements and procedures to verify quality acceptance criteria
• Work closely with the Hardware Tech Lead on mechanical-electrical fit and technical sign-off, and with Ops on commercial factory terms
• Make final decisions on mechanical design, material selection, tooling, and technical factory evaluation; make joint decisions with the Hardware Tech Lead on device form factor and the mechanical-electrical interface, and with Ops on commercial factory terms

• 7+ Years in mechanical engineering for consumer hardware, including at least one product taken to mass production with continued factory involvement
• Hands-on factory experience with line audits, first article inspection, and on-site corrective action
• Strong DFM/DFA, GD&T, and material selection skills for injection-molded plastic enclosures
• CAD experience with SolidWorks, Fusion 360, or equivalent, and FEA for structural and thermal validation
• Working knowledge of child product safety standards such as ASTM F963 or an equivalent regional standard, applied from the start of design
• Willingness to travel regularly to the manufacturing site during NPI
• English B2+ for factory, vendor, and certification communication
• Будет плюсом: speaker/microphone acoustic design inside a plastic enclosure, early-stage or startup hardware experience, direct factory negotiation on price, MOQ, and schedule, experience with a children’s or toy product, Mandarin or another language relevant to the target manufacturing region

• B2B contract
• Paid in USDT
• Europe preferred; this is not a strict requirement
• Regular travel to the manufacturing site during NPI
