- Diagnose and optimize compilation and linking bottlenecks through caching, parallelization, and distributed build strategies.
- Ensure seamless cross-compilation across multiple architectures, including x86 and ARM.
- Support testing in containerized and emulated environments using technologies such as Docker and QEMU.
- Write robust tooling and automation scripts in Python and Bash for environment provisioning, static analysis, and artifact generation.
- Partner closely with C++ software engineers to improve modular architecture, dependency management, and overall build reliability.
- Ensure reproducible build and release environments across local development, CI, and hardware-integrated systems.
Required Qualifications ===========================
- 3+ years of experience inw Build & Release Engineering, Developer Infrastructure, or DevOps supporting complex C++ codebases.

- Experience managing complex dependency graphs and modular build targets.
- Hands-on experience with containerization platforms such as Docker or Podman for build environment provisioning, dependency isolation, and reproducible CI/CD workflows.
Desired Qualifications
- Experience developing or supporting Embedded Linux systems using Yocto, Buildroot, or similar tools.
- Experience with hardware emulation tools such as QEMU.
- Familiarity with GitLab CI workflows.
- Experience working on embedded, aerospace, robotics, or other hardware-integrated software systems.
- Experience optimizing large-scale build systems using Bazel, remote execution, or similar distribu=-ed build technologies.
- Knowledge of linker internals, symbol visibility, and binary analysis tools such as ldd, nm, objdump, and readelf.
- Familiarity with static and dynamic analysis tools such as Clang-Tidy, AddressSanitizer (ASan), and SonarQube.
