About the Role

Aritech has been a trusted name in the security industry for decades, with a portfolio recognized for reliability, innovation and performance.

We are growing our Firmware Engineering team in Gdańsk and are looking for Firmware Engineers at different stages of their careers — with a primary focus on Mid-Level and Senior Engineers, while also welcoming applications from talented Junior Engineers with a strong interest in embedded systems and firmware development.

You will contribute to the development and evolution of ARITECH security systems and accessories for the EMEA market, working across the full firmware development lifecycle — from requirements and technical specifications, through design and implementation, to testing, troubleshooting and production support.

Depending on your experience level, you may take ownership of individual features and products, contribute to technical and architectural decisions, or work alongside experienced engineers while developing your embedded software expertise.

You will work on products such as security panels, keypads, touchscreens, card readers, sirens and sensors, collaborating closely with Hardware Engineering, Product Management, Quality Assurance, Compliance, Cybersecurity and global R&D teams.

As a Firmware Engineer, you will:

• Develop and maintain firmware for wired and wireless security devices and accessories.

• Implement firmware changes and new functionality across products such as Panels, Keypads, Touchscreens, Card Readers, Sirens and Sensors.

• Participate in the full firmware development lifecycle, from requirements and specification through design, implementation, testing and production support.

• Develop embedded software using C and, where applicable, C++.

• Work with bare-metal and RTOS-based environments, including FreeRTOS.

• Develop and maintain communication functionality using interfaces such as RS485 and wireless technologies.

• Contribute to solutions requiring low-power operation, real-time performance and efficient resource utilization.

• Participate in hardware-software integration and contribute to system and firmware architecture discussions.

• Troubleshoot technical issues and support root-cause analysis, debugging and bug fixing.

• Use development and debugging tools such as SWD/JTAG debuggers, logic analyzers and oscilloscopes.

• Contribute to firmware security mechanisms, including secure boot and secure firmware update solutions.

• Support verification, validation, certification and production activities.

• Prepare and maintain technical documentation, design specifications and development guidelines.

• Collaborate with Product Management, Hardware Engineering, QA, Compliance and Cybersecurity teams.

• Work closely with local and globally distributed engineering teams to ensure effective knowledge sharing and consistent implementation.

• Contribute to continuous improvement of engineering processes, tools and development practices.
