• Submit developed patches to upstream open-source projects and participate in community reviews.
• Maintain production toolchains, including backporting fixes, managing releases, and compatibility class="bg-amber-100">testing.
• Investigate and resolve compiler, linker, debugger, and runtime issues reported by users.
• Develop and improve automated class="bg-amber-100">testing and validation frameworks for toolchain components.
• Analyze generated code for correctness, performance, code size, and power efficiency.
• Collaborate with SDK, framework, silicon, and class="bg-amber-100">applications teams to improve developer experience across the Espressif ecosystem.
• Provide class="bg-amber-100">technical support and guidance to toolchain users.
• Evaluate and adopt modern development tools and workflows to improve engineering productivity and software quality.

Preferred Qualifications:

• Familiarity with at least one RISC architecture such as RISC-V, Xtensa, or ARM.
• Understanding of ELF, DWARF, ABI concepts, calling conventions, and linker scripts.
• Experience with compiler internals, debuggers, profilers, or development tools.
• Experience contributing to open-source projects and participating in upstream communities.
• Experience with class="bg-amber-100">Python scripting for class="bg-amber-100">automation, class="bg-amber-100">testing, or tooling development.
• Familiarity with static analysis, automated class="bg-amber-100">testing, and code quality tools.
• Understanding of embedded class="bg-amber-100">security concepts and memory safety.
• Experience with GitHub Actions, GitLab CI, Jenkins, or similar CI/CD platforms.
• Exposure to LLVM/Clang architecture and internals.
