Lead Hardware Engineer

Ajax Systems is expanding and is looking for a Lead Hardware Engineer to strengthen their team.

The role involves overseeing complex system architectures, consulting on cross-departmental optimizations, and mentoring the team on high-performance design methodologies.

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.

Benefits

• The opportunity to suggest and implement your own ideas that directly influence the product and its mass production;
• A place in a fast-growing company with a motivated and professional team;
• Competitive salary;
• Medical insurance;
• Corporate English classes;
• The opportunity to participate in Ajax’s internal beta-testing program for security systems;
• Discounts from partner companies;
• Discounts on Ajax products.
