Team Summary
Our Firmware RTOS team develops the mission-critical communications stack, operating on a dual-processor architecture. The team's objectives center on maintaining hard real-time determinism for the P25 LMR radio stack while integrating a massive suite of broadband connectivity modules without mutual interference.
Job Summary
We're seeking a Senior Embedded C/C++ Engineer with 7+ years of experience in RTOS. This is a unique opportunity to build a brand-new product from scratch and take complete ownership of the cellular integration and cross-processor connectivity logic for a next-generation device. As part of our team, you will be responsible for hardware bringup, architecture design, and business requirements implementation, ensuring the device achieves seamless 5G/LTE connectivity with reliable fallback to P25 LMR networks.
Responsibilities and Duties
-
Contribute to architectural decisions, component selection, and hardware-software co-design for the new platform.
-
Design and develop high-quality code in C/C++ for RTOS-based and simple scheduler-based MCUs.
-
Break down complex tasks, lead feature development, and drive prototypes to production-ready status.
-
Provide accurate estimates and development commitments based on the feature PRD.
-
Integrate and configure pre-certified 5G/LTE modem modules from the early bringup phase.
-
Develop the connectivity manager logic on the Communications Processor to handle seamless fallback transitions between 5G, LTE, and P25 LMR.
-
Design and document the Inter-Processor Communication (IPC) API contract between the Application Processor and communications controller.
-
Optimise firmware to support rigorous carrier and public safety certifications.
-
Collaborate closely with software, hardware, and RF teams to create high-quality prototypes and innovative products.
-
Regularly report project status and technical risks during meetings with management.
Qualifications And Skills
-
At least 7 years of commercial experience in embedded development, with expertise in C/C++ and deep knowledge of RTOS and microcontroller architectures (ARM, RISC-V).
-
Proven track record of bringing up new hardware and working with reference design boards or evaluation kits.
-
Extensive experience designing high-bandwidth, low-latency Inter-Processor Communication (IPC).
-
Solid experience integrating cellular modems (AT commands, modem control layers) at the firmware level.
-
Knowledge of communication protocols (I2C, SPI, UART) and low-level device driver integration.
-
Proficiency in the full SDLC, including professional engineering practices like Git, CMake, code reviews, and continuous integration.
-
Ability to work with high autonomy and take ownership of complex modules started from the ground up.
-
Excellent communication skills for technical discussions and documentation, with a collaborative mindset for cross-functional team environments.
-
At least an Upper-Intermediate level in both written and spoken English (B2).
Nice to have
-
Familiarity with 3GPP Release 16/17 standards, MCPTT frameworks, Wi-Fi 7, Bluetooth 6.0, UWB, or GNSS integration.
-
Experience in basic HW diagnostics (using oscilloscopes, logic analyzers) and basic soldering.
-
Experience with cellular logging and diagnostic tools
-
Familiarity with RF signal processing or physical coexistence challenges.
-
Experience in embedded Linux development.
-
Experience using AI-powered tools to enhance productivity and code quality.
We offer multiple benefits that include
