Job description

We are seeking a Mechanical Engineer with strong expertise in product casing and mold design to join our R&D team.

Key Responsibilities

• Design and model product casings, enclosures, and mechanical components using 3D CAD software (SolidWorks, Fusion, or equivalent).
• Generate detailed 2D drawings and technical documentation for manufacturing.
• Develop injection mold designs, collaborate with external toolmakers, and review tooling drawings.
• Optimize designs for injection molding, die‑casting, CNC machining, and 3D printing using DFM/DFA principles.
• Select materials for strength, durability, environmental resistance (IP65+), and cost efficiency.
• Rapidly prototype designs via 3D printing and validate fit, form, and function.
• Conduct tolerance analysis and stress simulations.
• Support testing for environmental robustness (vibration, temperature, sealing).

Cross‑Functional Collaboration

• Work closely with electronics, firmware, and industrial design teams to integrate PCBs, batteries, antennas, and connectors into enclosures.
• Coordinate with suppliers and manufacturing partners (local and international) on mold fabrication, production, and quality checks.
• Research new materials, manufacturing methods, and processes.
• Drive improvements in mechanical reliability, weight, and production cost.

Requirements

• Bachelor's degree in Mechanical Engineering or related field.
• Proficiency in 3D CAD (SolidWorks, Creo, Fusion, or similar).
• Strong knowledge of plastics, polymers, and metals used in electronic product housings.
• Understanding of DFM (Design for Manufacturability) and DFA (Design for Assembly).
• Experience producing manufacturing drawings and GD&T (Geometric Dimensioning & Tolerancing).

Preferred / Nice to Have

• Familiarity with PCB and electronics integration into housings.
• Familiarity with electronics circuit design and firmware development.
• Experience with sealing designs for ruggedized or waterproof devices (IP ratings).
• Basic knowledge of thermal management for electronic enclosures.
• Exposure to compliance / certification requirements (CE, ICASA, FCC, RoHS).

Soft Skills

• Strong problem‑solving and analytical thinking.
• Attention to detail and ability to balance design with cost/manufacturing constraints.
• Team player who can collaborate with cross‑disciplinary teams (electronics, firmware, QA, manufacturing).
• Clear communicator, able to work with external vendors and internal stakeholders.
