Role Required Description
Embedded Developer Required Understands C++ memory management basics for microcontrollers. Writes simple drivers and peripheral access code. Follows coding standards for embedded safety-critical systems.
IoT Engineer Uses C++ to implement basic firmware logic for IoT sensor nodes. Understands constrained memory environments and interrupt handling. Works with HAL libraries under guidance.
Systems Programmer (C/C++) Applies C++ for low-level systems programming tasks including memory-mapped I/O and register manipulation. Understands toolchain basics: cross-compilation, linker scripts, and debugging via JTAG/SWD.
Role Required Description
Embedded Developer Required Applies C++17 for embedded: constexpr computations, type-safe register wrappers, CRTP for HAL. Avoids dynamic allocation and exceptions.
IoT Engineer Applies C++17 in embedded IoT with constraints: no exceptions, no RTTI, minimal heap. Develops type-safe peripheral APIs using templates and constexpr.
Systems Programmer (C/C++) Independently applies C++ for Embedded in practice. Understands trade-offs of different approaches. Solves typical tasks independently.
Role Required Description
Embedded Developer Required Designs zero-cost abstraction HAL in C++ with templates. Applies compile-time polymorphism, optimizes binary size through LTO and -fno-rtti.
IoT Engineer Required Designs C++ embedded frameworks for IoT platform. Uses CRTP, policy-based design for zero-cost abstractions. Ensures predictable execution time without allocations.
Systems Programmer (C/C++) Required Has deep expertise in C++ for Embedded. Designs solutions for production systems. Optimizes and scales. Mentors the team.
Role Required Description
Embedded Developer Required Defines C++ subset for the embedded team. Establishes guidelines for STL usage, templates, memory management on resource-constrained platforms.
IoT Engineer Required Establishes C++ embedded development standards: MISRA C++, coding guidelines. Defines architectural patterns and libraries for reuse across IoT projects.
Systems Programmer (C/C++) Required Defines C++ for Embedded strategy at team/product level. Establishes standards and best practices. Conducts reviews.
Role Required Description
Embedded Developer Required Shapes C++ adoption strategy for embedded: defines allowed C++ subset per safety level, evaluates compiler support across targets, establishes migration path from C codebases.
IoT Engineer Required Defines C++ embedded strategy at company level. Evaluates Rust vs C++ for new IoT projects. Builds platform architecture for IoT product family.
Systems Programmer (C/C++) Required Defines C++ for Embedded strategy at organizational level. Establishes enterprise approaches. Mentors leads and architects.
