Join Our Team asa Senior Software Engineer!

Are you an experienced software engineer who thrives on building the core technology behind high-reliability embedded systems? Do you excel in fast-paced environments where precision and collaboration are key? If so, this role is for you! We're seeking a Senior Software Engineer with strong expertise in low-level driver and kernel development in C to design, integrate, and verify system-level software for embedded platforms, supporting platform bring-up and seamless system integration.

About the Company:

Thomas Global Systems is a leader in the design, manufacture and support of high-integrity aviation and defense electronics, operating out of locations in Sydney, Australia and Irvine, California.

About the Role:

The Senior Software Engineer plays a key role in developing and integrating low-level system software that enables high-reliability embedded platforms for aerospace and defense applications. This position is responsible for designing, implementing, and verifying kernel-level drivers, user-space libraries, and other foundational software components primarily in C. Working closely with hardware, systems, and test engineering teams, the Senior Software Engineer supports platform bring-up, system integration, performance optimization, and troubleshooting of complex embedded environments. This role requires deep technical expertise in low-level programming, strong analytical abilities, and the capacity to independently solve complex system challenges within a fast-paced, mission-critical engineering environment.

What's on Offer:

• A varied, fast paced role with an innovative and respected leader in mission‑critical aerospace and defense products.
• Competitive remuneration and comprehensive benefits package.
• Join a team of skilled and motivated people committed to innovation, collaboration, and national security outcomes.

What You'll Do:

• Design, develop, and maintain kernel-level drivers/user space library and low‑level system software.
• Implement robust, efficient, and portable solutions using the C programming language.
• Collaborate with hardware, systems, and test engineering teams to support driver integration and troubleshooting.
• Analyze system performance, optimize resource utilization, and ensure reliable behavior under real‑time constraints.
• Participate in requirement captures, SW ICD generation, design reviews, code reviews, and system debugging activities.
• Support verification and documentation activities as needed to meet project and certification requirements.

What You'll Bring:

• Bachelor's degree in computer science, Computer Engineering, or a related field; or equivalent combination of education and experience.
• At least 10 years of progressive experience in low-level software engineering, including embedded, driver, and kernel development.
• Expert proficiency in C for embedded and system-level development.
• Solid understanding of low-level OS concepts, memory management, multithreading, hardware interfaces, and real-time constraints.
• Ability to work with hardware teams to debug board-level issues, timing, and interface behaviors.
• Strong problem-solving skills and ability to work independently with minimal guidance.

Preferred/Bonus Qualifications:

• Experience developing drivers for LynxOS / LynxRTOS.
• Experience with Linux PCI Utilities Library.
• Familiarity with TCL and other scripting languages (e.g., Python, Bash, Perl).
• Knowledge of DO-178 development processes, documentation workflows, and certification considerations.
• Experience working in safety-critical or mission-critical embedded environments.
• Understanding of BSPs, RTOS internals, or avionics development practices.
