Embedded Connectivity Engineer
SQUAD
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
The environment of equal opportunities, transparent and value-based corporate culture, and an individual approach to each team member
Competitive salary packages with performance-based annual reviews.
Opportunity to receive a Performance Bonus for your individual achievements and a Loyalty Bonus recognizing your dedication to the company.
Employment via Contract of Employment (UoP) in complete alignment with Polish Labour Law.
Guaranteed paid vacation, public holidays, and medical leaves as per statutory regulations.
Continuous growth and development opportunities through internal knowledge hubs, corporate courses, and free English classes
Comprehensive private medical insurance to supplement your standard NFZ coverage.
