This role involves low-level embedded Linux development as well as application-level VoIP software development. The successful candidate should be comfortable working across the embedded software stack, including bootloaders, the Linux kernel, device drivers, system software, and applications.

A strong understanding of resource-constrained embedded systems, debugging, and performance optimization is important for this role.

• Develop and maintain software for embedded Linux-based platforms.

• Work with bootloaders, the Linux kernel, and device drivers, including modifying and debugging existing code when required.

• Configure, build, and troubleshoot the Linux kernel and bootloader for target hardware.

• Use embedded toolchains and cross-compilation environments to build system and application software for target platforms.

• Work with real-time and performance-sensitive Linux environments.

• Debug issues across the software stack, from bootloader and kernel-level problems to user-space applications.

• Work with IPC (Inter-Process Communication), multithreading, synchronization, and related system-level concepts.

• Analyze and optimize CPU usage, memory usage, startup time, and overall system performance.

• Develop and maintain embedded software for VoIP telephone products.

• Work with SIP and related VoIP/telephony technologies.

• Investigate and resolve signaling, media, networking, and system integration issues.

• Develop efficient software suitable for embedded systems with limited CPU and memory resources.

• Design, implement, test, and maintain software primarily in C and C++.

• Apply object-oriented design principles where appropriate.

• Diagnose complex software problems using effective debugging techniques and tools.

• Work with static and dynamic libraries, including library linking and dependency management.

• Use development environments and tools such as Eclipse, Visual Studio, GDB, and related embedded development/debugging tools.

• Participate in code reviews and contribute to software design and architecture discussions.

• Strong experience in embedded software development using C/C++.

• Hands-on experience developing software in a Linux embedded environment.

• Working knowledge of Linux kernel architecture and kernel-level development.

• Experience working with and debugging Linux device drivers.

• Experience working with bootloaders and the embedded Linux boot process.

• Hands-on experience with cross-compilation, embedded toolchains, and target platform builds.

• Good understanding of IPC, multithreading, synchronization, and process management.

• Strong debugging and problem-solving skills, including the ability to troubleshoot issues across multiple layers of an embedded system.

• Understanding of memory and performance constraints common to embedded systems.

Experience with any of the following would be an asset but is not required:

• Telephony systems and technologies.

• VoIP protocols, particularly SIP.

• Real-time Linux and performance-sensitive applications.

• Networking protocols and network programming.

• Strong analytical and problem-solving skills.

• Clear and effective communication skills.

• Responsible, self-motivated, and proactive.

• Comfortable working independently as well as collaboratively within a team.

• Able to prioritize and deliver high-quality work under schedule constraints.
