Senior Embedded Product Engineer Greece

We are seeking a Senior Embedded Product Engineer to design and develop OQs satellite-enabled devices and reference platforms supporting both IoT and emerging 5G NTN Direct-to-Device (D2D) capabilities.

This is a hands-on engineering role focused on hardwarefirmware co-design embedded software development and system integration. The position covers the full development lifecycle from concept and prototyping through bring-up validation and product readiness ensuring robust operation across satellite and terrestrial networks.

The role will also support the evolution toward integration with third-party devices and network-based services through development kits and reference designs.

Tasks

• Develop embedded systems for satellite IoT devices and reference platforms supporting both product and integration use cases.
• Lead hardwarefirmware co-design ensuring tight coupling between PCB design peripherals and embedded software architecture.
• Design review and bring up complex PCBs including component selection interface definition and board-level debugging.
• Implement and maintain embedded software stacks including drivers middleware and application layers in C and C.
• Architect and optimize real-time behavior using FreeRTOS including task scheduling concurrency and resource management.
• Design and implement power management strategies aligned with duty-cycled network-driven transmission and long-life operation.
• Integrate and validate key subsystems including modems GNSS sensors and multi-interface connectivity (wired and wireless).
• Support device compatibility with NTN and cellular networks including handling of modem interfaces and connectivity behavior.
• Contribute to system-level integration and troubleshooting across device network and backend interfaces.
• Establish robust debugging test and validation approaches at both board and firmware levels to ensure reliable field operation.
• Ensure designs are production-ready meeting requirements for manufacturability reliability and long-term maintainability.

Requirements

• 7 years in embedded systems with ownership of full product development cycles (prototype production).
• Strong expertise in C/C embedded development with real-time and resource-constrained systems.
• Proven ability to co-design hardware and firmware bridging PCB-level decisions with software architecture.
• Hands-on experience with PCB design and bring-up (Altium or equivalent) including system-level debugging.
• Deep understanding of RTOS-based architectures (FreeRTOS or similar) and deterministic system design.
• Strong track record in low-level driver development and hardware interfacing.
• Experience building low-power embedded systems optimized for long-life or duty-cycled operation.
• Comfortable working across hardware interfaces and communication protocols in complex devices.
• Strong engineering rigor in debugging validation and production readiness.
• Proven ability to write clean structured technical documentation and drive engineering clarity.

Nice to Have:

• Experience with modem integration RF front-end systems or 5G communication protocols including practical implementation and system-level troubleshooting.
• Background in designing rugged outdoor or mission-critical hardware systems for harsh environmental and long-life deployment conditions.

Benefits

• Hybrid working environment.
• Opportunity to work on flagship EU space mission projects.
• A dynamic high-growth environment with career development opportunities.
• Regular company events and team activities.
