Description
Ajax Systems is expanding and is looking for a Senior/Lead Hardware Engineer to strengthen our team in China.
As a Senior Hardware Engineer, you will not only design circuits but also serve as a technical cornerstone for our R&D in China. We are looking for an expert who brings strategic value: someone who can oversee complex system architectures, consult on cross-departmental optimizations, and mentor the team on high-performance design methodologies. You will be the bridge between innovative concepts and mass-scale manufacturing.
Key Responsibilities
- Develop sophisticated schematic solutions and PCB layouts for new Ajax devices, ensuring high reliability and scalability.
- Proactively identify opportunities for cost reduction and performance enhancement through component unification and innovative architectural shifts.
- Lead complex hardware projects from initial concept through to mass production (10,000+ units/month), ensuring all technical risks are mitigated.
- Act as a subject matter expert for the firmware and supply chain teams to optimize the hardware-software interface and manufacturing yield.
- Lead the “bring-up” process, debugging complex issues and defining rigorous testing protocols for design validation.
Requirements
- Expert-level calculation of circuit elements and high-fidelity simulations of device behavior.
- Professional proficiency in Altium Designer (experience with managed libraries and 3D modeling is preferred).
- Proven track record of designing for LVD/EMC compliance and mass manufacturing (DFM/DFT).
- Deep expertise in designing both battery-powered and mains-powered (85–265 VAC) devices.
- Experience preparing comprehensive production documentation (BOM management, Gerber files, assembly drawings) using Git for version control.
- Fluent English is required for technical documentation and international collaboration.
Preferred Qualifications
- Direct experience working with vendors and manufacturers for high-volume production.
- Advanced understanding of Signal Integrity (SI) and Power Integrity (PI). Experience with S-parameters, PDN impedance modeling, and TDR measurements.
- Ability to write or review embedded software (C/C++, STM32) to facilitate deep-level debugging and hardware-software co-design.
- Experience guiding products through global certifications (UL, CE, RED), beyond basic compliance.
