Job Description

We are seeking a Senior Embedded Product Engineer to design and develop OQ’s 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 hardware–firmware 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 hardware–firmware 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.
