Responsibilities

Develop and maintain C++20 / Qt 6 applications for ARM-based embedded Linux controllers used in commercial hydronic and water heating products.
Implement new features and resolve defects across the firmware stack, including UI screens, control logic, and I/O handling for analog inputs, RTDs, flow sensors, relays, and touchscreens.
Write clean, deterministic C++ code suitable for real-time control, avoiding dynamic memory allocation in time-critical paths.
Integrate device communication over Modbus, BACnet, RS-485/RS-232, CAN bus, and Ethernet.
Build and cross-compile firmware using CMake and Yocto toolchains; deploy binaries to target hardware via SSH for on-device debugging in Qt Creator.
Write and maintain unit tests (Qt Test / GoogleTest) and Doxygen documentation per team coding standards (. clang-format, license headers, enum constants).
Contribute to Jenkins CI/CD pipelines for automated builds, testing, and packaging.
Use Git/GitHub for version control; triage issues, reproduce reported bugs, and submit changes through pull requests and code reviews.
Utilize AI-assisted development tools (e.g., GitHub Copilot) effectively and responsibly to streamline development, increase efficiency, and strengthen code quality.
Read schematics and PCBs to support hardware/software integration and lab validation against test benches.
Collaborate cross-functionally with Controls, Hardware, QA, and Product teams on NPD projects from concept to acceptance.
Assume responsibility for other projects assigned by the Embedded Software Engineering Manager or Company management.
Responsibility directly tied to Watts Values (Integrity, Accountability, Continuous Improvement, Transparency)
