Ajax Systems is looking for an experienced Mechanical Engineer to join our team. Ajax Systems is a developer and manufacturer of advanced security systems with smart home capabilities. We are a full-cycle product company from idea and engineering to mass production. Our portfolio includes 70+ devices that protect properties from intrusion, fire, and flooding, while also enabling smart control of electrical appliances. Today, Ajax Systems protects over 2 million users in 169 countries worldwide and has received Europe’s highest security awards. We are proud to be a Ukrainian success story, a company driven by innovation, resilience, and strong engineering culture.
Key Tasks:
- Complete lifecycle design of plastic enclosures and mechanical assemblies for consumer electronics.
- Development of DFM- and DFH-oriented solutions considering mass production processes (plastic injection molding, assembly, sealing, serviceability).
- Collaboration with hardware and embedded engineers, industrial designers, technologists, quality control, and manufacturing departments.
- Design of ergonomic, intuitive solutions adaptable to different operating environments.
- Preparation of production transfer documentation (2D drawings, specifications, technical requirements, 3D models for molds).
- Support of mold development and approval of modifications after initial mold trials (T0–T2), including defect analysis.
- Participation in testing and feedback from prototypes and production, incorporating design improvements.
- Verification of engineering compliance of the finished product with expected technical parameters (stiffness, assembly, weight, IP protection).
- Oversight of the product lifecycle from concept to mass production, including cost analysis and assessment of the impact of design decisions on production costs.
- Communication with Chinese factories: technical specifications, drawing reviews, change control, feedback on prototypes and production samples.
- Assessment of manufacturing risks in China: equipment limitations, mold quality, shrinkage, production tolerances, and the influence of packaging and logistics on design.
- Inspection of samples from China: defect analysis (shrinkage, warping, poor casting), initial product assembly, and reporting with recommendations.
- Consideration of potential scaling difficulties in China: timeline tracking, mold duplication, and price optimization.
- Continuous communication via email, video calls, document comments (in English), and participation in editing specifications based on feedback from the Chinese side.
