In this role, strong expertise in PHP, Node.js, and containerized environments (Docker) is essential. Experience with SQL, NoSQL, and specifically MongoDB will help you hit the ground running.

We also value developers who understand infrastructure and architecture, write clear documentation, and feel comfortable working in an Agile setup (Jira, Confluence).

• Build and improve the backend for our core products: EWQ Queue Management, Digital Signage, and Electronic Shelf Labels
• Take ownership of backend architecture and deliver high-quality, scalable solutions

• Join customer workshops to turn real-world needs into robust technical solutions
• Create clear technical documentation and contribute to a smooth Agile workflow
• Help shape our backend technologies and development practices moving forward

Additionally, its a plus if you have practical experience with the ELK stack for monitoring, as well as a background working with message queues, microservice architectures, or event-driven systems. You work independently, solve problems proactively, and enjoy learning new things. You want your work to have a visible impact.
