About the Position

Senior Embedded Software Developer (Connectivity&Protocols)

Join Klika-Tech, Inc as a Senior Embedded Software Developer to architect a next-gen multi-core System-on-Chip (SoC), focusing on secure, low-power IoT applications.

About the Project

Join a strategic partnership with a global leader in long-range wireless technology to architect the software ecosystem for a next-generation multi-core System-on-Chip (SoC). This engagement goes beyond standard firmware development; you will co-develop a comprehensive developer platform that transforms complex multi-core hardware into an accessible, world-class microcontroller product. By leveraging open-source real-time operating systems like Zephyr and FreeRTOS, and implementing cutting-edge hardware-enforced security frameworks (PSA Level 3, TrustZone, TEE), you will empower the global embedded community to deploy secure, ultra-low-power IoT applications. You will work within a specialized team structure to deliver a modern toolchain centered around Visual Studio Code, ensuring a seamless “edit-build-debug” experience for the next wave of wireless innovation!

Your Role

• Dive into complex, proprietary wireless SDKs to understand, navigate, and safely modify their internal hardware scheduling mechanics.
• Develop and integrate an access control layer to manage concurrent, multi-protocol operations over shared hardware interfaces (e.g., SPI bus to RF front-ends).
• Solve practical, real-time concurrency challenges, including managing priority overrides and conflict-free hardware access.
• Adapt and optimize system code for both bare-metal and standard RTOS environments.
• Collaborate closely with Solution Architects to map APIs across various MCU families.

Requirements

• Solid C programming experience targeting resource-constrained embedded systems.
• Strong understanding of bare-metal and real-time operating systems (RTOS) execution environments.
• Proven ability to handle time-critical operations, strict real-time constraints, and interrupt latency (typical in MAC layer scheduling or high-speed communication buses).
• Practical experience dealing with hardware-level concurrency, shared bus arbitration (e.g., SPI/UART contention), and low-level scheduling.
• Demonstrated ability to learn quickly and effectively troubleshoot large, complex, or third-party codebases without requiring perfect documentation.
• Comfortable working alongside hardware abstraction layers (HAL) and direct register manipulation.
• A pragmatic, problem-solving mindset with a strong engineering foundation.

Nice to Have

• Previous exposure to the internals of wireless protocol stacks (e.g., long-range RF, mesh networks, or personal area networks).
• Experience developing resource scheduling logic or arbitration layers for shared hardware resources.
• A basic understanding of RF fundamentals, physical layer interactions, and regional radio compliance parameters.
