Backend Engineer – Embedded / Real-Time Systems

Paris (South of Paris / Île-de-France)

Permanent, CDI

Salary based on experience

Do you want to build backend software that runs inside real products, where performance, timing, and system behaviour really matter?

This opportunity is with a European technology company that designs and manufactures high-end professional hardware systems combining real-time processing, networking, and intuitive control interfaces. Their products are used worldwide in demanding environments such as live events, broadcast, corporate presentation, and control rooms, where reliability and responsiveness are critical.

For this role they require you to be on-site 3 days per week and they require European Citizenship,

What you will do:

• Design and develop backend services for embedded products, running on Linux-based systems
• Build and maintain real-time communication and synchronisation layers (WebSockets, event-driven architectures)
• Work closely with embedded, frontend, and system architects to integrate backend logic into complex hardware-driven products
• Ensure software quality through code reviews, automated testing, and CI/CD pipelines
• Contribute to architectural decisions and continuous improvement of development practices

Key skills required:

• Strong experience as a backend developer (Node.js, TypeScript; NestJS a plus)
• Experience working on embedded products or systems with real-time constraints (not pure web/SaaS)
• Good understanding of client/server synchronisation and real-time communication
• Familiarity with Linux-based environments and system-level constraints
