## Job description

Ajax Systems is expending and is looking for a Hardware Engineer to strengthen our team in Vietnam.

Ajax Systems is an international tech company and the largest manufacturer of security systems in Europe, with over 4.5 million end users and 330K PRO users in more than 180 countries worldwide. The company offers end-to-end solutions for protecting homes and businesses of any scale. To date, the Ajax product portfolio includes 280 devices for intrusion protection, video surveillance, fire and life safety, and comfort and automation.

As a Hardware Engineer, you will not only design circuits but also serve as a technical cornerstone for our R&D in Taiwan. 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

Architecture & Design: Develop sophisticated schematic solutions and PCB layouts for new Ajax devices, ensuring high reliability and scalability. Strategic Optimization: Proactively identify opportunities for cost reduction and performance enhancement through component unification and innovative architectural shifts. Project Oversight: Lead complex hardware projects from initial concept through to mass production (10,000+ units/month), ensuring all technical risks are mitigated. Cross-Functional Consultation: Act as a subject matter expert for the firmware and supply chain teams to optimize the hardware-software interface and manufacturing yield. Prototype Lifecycle: Lead the “bring-up” process, debugging complex issues and defining rigorous testing protocols for design validation.

## Requirements

Advanced Circuit Design: Expert-level calculation of circuit elements and high-fidelity simulations of device behavior. EDA Mastery: Professional proficiency in Altium Designer (experience with managed libraries and 3D modeling is preferred). Design for Excellence (DfX): Proven track record of designing for LVD/EMC compliance and mass manufacturing (DFM/DFT). Power Management: Deep expertise in designing both battery-powered and mains-powered (85–265 VAC) devices. Full Lifecycle Ownership: Experience preparing comprehensive production documentation (BOM management, Gerber files, assembly drawings) using Git for version control. Communication: Fluent English is required for technical documentation and international collaboration.

## Preferred Qualifications

Supply Chain Leadership: Direct experience working with vendors and manufacturers for high-volume production. High-Speed Design: Advanced understanding of Signal Integrity (SI) and Power Integrity (PI). Experience with S-parameters, PDN impedance modeling, and TDR measurements. System-Level Thinking: Ability to write or review embedded software (C/C++, STM32) to facilitate deep-level debugging and hardware-software co-design. Regulatory Mentorship: Experience guiding products through global certifications (UL, CE, RED), beyond basic compliance.
