Job Description

Ajax Systems is an international technology company and the largest European developer and manufacturer of Ajax security systems with smart home capabilities. It's a complete ecosystem comprising 180 devices, mobile and desktop applications, and server infrastructure. Every year, we demonstrate exponential growth in both team size and user base worldwide. Currently, the company has over 4,100 employees, and Ajax sensors protect 4 million users in more than 187 countries.

The Device Department focuses on developing devices for security and automation. We tackle significant challenges in areas such as:

  • Low-Power: Devices must operate for the longest possible time on standard batteries.
  • Cost-Effectiveness: Mass-produced products must remain within the mid-price segment.
  • DFM (Design for Manufacturing) and DFH (Design for Human): Circuitry, enclosures, and other elements must be easily replicable in hundreds of thousands of devices during production without compromising quality.

Development primarily utilizes STM32 (though other MCUs and SoCs are also used) with Embedded C. We have already assembled strong expertise and talented individuals, including Hardware and Embedded C engineers, industrial designers, and mechanical engineers.

Responsibilities:

  • Develop circuit solutions and printed circuit boards (PCBs) for new Ajax devices.
  • Work on improving existing Ajax devices.
  • Select component replacements, including documenting the necessary tests.
  • Perform initial verification and debugging of prototypes (bring-up).
  • Bring projects to mass production (10,000+ units per month).

Requirements:

  • Device circuit design: calculating circuit elements, simulating device operation.
  • PCB design using Altium Designer.
  • Device design considering certification requirements (LVD, EMC).
  • Device design considering mass production requirements.
  • Low-power device design.
  • Networked device design (230 VAC).
  • Device cost optimization (component base unification, alternative component sourcing).
  • Prototype debugging, identifying and resolving device issues.
  • Preparing documentation for PCB manufacturing and assembly.
  • Working with version control systems (git).
  • English language proficiency sufficient for reading technical documentation.

Bonus Points:

  • Experience with supply chain management for high-volume production (10,000+ units per month).
  • Experience in embedded software development for modern platforms (STM32, etc.), sufficient for debugging one's own developments.
  • Understanding of signal integrity / power integrity principles in device design, as well as experience in modeling/characterizing topologies (S-parameters, PDN impedance).

What You Will Get:

  • The opportunity to propose and implement your own ideas that impact products and production.
  • Work in a motivated team with a zero-bullshit culture.
  • Competitive salary.
  • Medical insurance.
  • Corporate English language courses.
  • Compensation for professional training.
  • Opportunity to participate in the beta testing project for Ajax security systems – receiving and testing new gadgets before their release.
