- Build a phased migration and modernization roadmap, including cost and effort estimation.

- Define build and compilation toolchains, CI/CD approach, and testing strategies for the modernized C codebase.

- Collaborate with TuxCare consulting team to leverage expertise on legacy OS support and compatibility layers.

- Document all findings, prepare proposal decks, and support presales/solutioning discussions.

Required Skills & Experience :

years of experience in Linux systems engineering and solution architecture.

- Strong expertise in C development, compilation toolchains (GCC), and porting legacy code to modern Linux.

- Deep knowledge of Red Hat Enterprise Linux and AlmaLinux operating systems and their libraries.

- Hands-on experience designing and deploying workloads on Amazon Web Services (AWS).

- Familiarity with low-level Linux concepts: IPC, shared memory, semaphores, signals, and system daemons.

- Experience with refactoring/modernizing legacy codebases for compatibility with modern OS and libraries.

- Strong documentation, estimation, and solution proposal skills.

- Experience migrating monolithic C systems to modular or containerized architectures.
